condition statement 28 00:02:14,144 --> 00:02:20,288 Comment controlling compilation with preprocessor 29 00:02:20,544 --> 00:02:23,360 Testing program 30 00:02:23,616 --> 00:02:28,480 operationg mode change for program testing in debug mode 31 00:02:29,760 --> 00:02:35,648 monitoring variables symbol browser and watch table 32 00:02:36,160 --> 00:02:42,304 New functions in St editor as of version 4.2 33 00:02:43,328 --> 00:02:45,376 Setting the breakpoint 34 00:02:45,632 --> 00:02:51,776 Specify the debug test group of useful other things and so on 35 00:02:54,848 --> 00:03:00,992 Let's talk or first page of this chapter 36 00:03:01,248 --> 00:03:04,576 Integration of St in Scout 37 00:03:07,392 --> 00:03:13,536 You see here in symbol browser compile menu program status 38 00:03:13,792 --> 00:03:19,936 st editor is opened under ST1 unit that are several different 39 00:03:20,192 --> 00:03:22,752 1 + 2 +3 + 4 40 00:03:23,008 --> 00:03:29,152 Three and four Programs located description in interface section 41 00:03:29,920 --> 00:03:33,248 there is an implementation section 42 00:03:35,296 --> 00:03:41,440 So also an external editor can be used in integrated in 43 00:03:41,696 --> 00:03:44,512 simotion workbench if you want 44 00:03:49,376 --> 00:03:55,520 To generate an st source for just double click to insert St source for 45 00:03:55,776 --> 00:03:57,568 write The name of your source 46 00:04:00,128 --> 00:04:02,688 Names are not case sensitive 47 00:04:03,712 --> 00:04:07,040 You may use letters numbers or _ 48 00:04:10,880 --> 00:04:12,928 and name 49 00:04:13,184 --> 00:04:19,327 Contains up to 128 characters 50 00:04:21,631 --> 00:04:27,775 you will see here how do specified St Source file compile settings we have already done 51 00:04:29,567 --> 00:04:34,431 If you want you can ask someone or read the detail 52 00:04:38,015 --> 00:04:41,599 settings for working with St editor 53 00:04:42,367 --> 00:04:47,999 You'll see here font-time font size format settings for display 54 00:04:52,351 --> 00:04:57,215 I'll see you see here the ccommand library on the left side and project window 55 00:04:59,263 --> 00:05:05,407 Identifiers and syntax coloring in the ST editor 56 00:05:06,687 --> 00:05:11,039 User-defined name is colored as black 57 00:05:11,295 --> 00:05:16,159 Favorite color is blue and contant color as pink 58 00:05:16,671 --> 00:05:21,535 comments as color as green color 59 00:05:26,655 --> 00:05:29,471 There are some restrictions 60 00:05:31,263 --> 00:05:33,311 There is no umlaut 61 00:05:35,359 --> 00:05:38,431 That means a double quotation 62 00:05:40,479 --> 00:05:42,271 not case sensetive 63 00:05:43,551 --> 00:05:46,367 must not start with a digit 64 00:05:47,647 --> 00:05:49,183 Names identifiers 65 00:05:49,439 --> 00:05:55,583 Should not start with an underscore because it's reserved for siemens 66 00:05:55,839 --> 00:06:01,471 And identifiers must not be same as key words 67 00:06:03,519 --> 00:06:06,079 Yep 68 00:06:07,359 --> 00:06:13,503 So reserved keywords if as program and so on 69 00:06:15,551 --> 00:06:16,831 Next page 70 00:06:18,111 --> 00:06:23,743 And you see here the structure of an ST source 71 00:06:23,999 --> 00:06:25,535 for connection 72 00:06:26,559 --> 00:06:32,703 Two other units and execution system unit to describe your 73 00:06:32,959 --> 00:06:36,287 Functional interface section of unit 74 00:06:36,543 --> 00:06:41,407 and implementation section later on 75 00:06:41,919 --> 00:06:46,015 Define and write your own program for function 76 00:06:46,783 --> 00:06:50,367 returns a value as 77 00:06:50,623 --> 00:06:51,903 You describe 78 00:06:52,159 --> 00:06:55,487 at this acse long-real type 64-bits 79 00:06:57,791 --> 00:07:01,375 Function block and program 80 00:07:05,471 --> 00:07:09,823 So components of interface section 81 00:07:13,151 --> 00:07:14,943 Is use package 82 00:07:15,711 --> 00:07:18,527 This is the technology package Cam 83 00:07:19,039 --> 00:07:19,807 path 84 00:07:20,319 --> 00:07:22,623 TCONTROL 85 00:07:23,135 --> 00:07:25,183 Possibilities 86 00:07:25,439 --> 00:07:26,975 Use Library 87 00:07:27,743 --> 00:07:30,559 created Library name 88 00:07:31,071 --> 00:07:34,399 uses keywords for 89 00:07:34,655 --> 00:07:38,239 Make a connection to other unit 90 00:07:40,287 --> 00:07:45,407 Public variables and other types described with type 91 00:07:47,711 --> 00:07:52,319 here are the color red yellow blue 92 00:07:52,831 --> 00:07:55,135 it is an enumeration 93 00:07:55,391 --> 00:08:00,511 Red means zero yellow means one blue means 2 94 00:08:01,791 --> 00:08:03,071 This is a type 95 00:08:07,935 --> 00:08:13,311 volatile Global variables set an actual as long real the time and 96 00:08:14,079 --> 00:08:16,895 It's not initialized this case 97 00:08:17,151 --> 00:08:20,223 For specification of public blocks 98 00:08:21,503 --> 00:08:25,599 here interface section program name 99 00:08:25,855 --> 00:08:27,903 And function name 100 00:08:29,695 --> 00:08:30,975 So 101 00:08:31,487 --> 00:08:36,607 implementation section 102 00:08:37,119 --> 00:08:39,167 The program code for display 103 00:08:46,079 --> 00:08:52,223 next thing is components of the implementation section here 104 00:08:54,527 --> 00:09:00,671 on this page an Unit example implementation private and unit global 105 00:09:00,927 --> 00:09:06,303 variables and datatypes is the similar description type 106 00:09:08,607 --> 00:09:10,143 Global variables 107 00:09:10,655 --> 00:09:11,679 Not retain 108 00:09:12,191 --> 00:09:16,799 Implementation of public and private blocks 109 00:09:17,055 --> 00:09:19,871 Program function and function blocks 110 00:09:22,175 --> 00:09:23,455 Also 111 00:09:24,223 --> 00:09:30,367 We will see in detail later on in next pages that are some decleration party 112 00:09:30,623 --> 00:09:34,719 parts inside the function 113 00:09:34,975 --> 00:09:37,023 And program and function block 114 00:09:40,351 --> 00:09:43,423 so... 115 00:09:44,447 --> 00:09:45,727 next page 116 00:09:46,495 --> 00:09:51,359 Declerations in the interface and implementation parts 117 00:09:51,615 --> 00:09:54,943 global constant decleration 118 00:09:55,199 --> 00:09:56,223 Example 119 00:09:56,479 --> 00:09:58,527 Real 120 00:09:59,295 --> 00:10:02,367 constant as pink color 121 00:10:06,207 --> 00:10:07,231 type 122 00:10:07,487 --> 00:10:09,279 Real motor 123 00:10:09,791 --> 00:10:12,351 Structure 124 00:10:12,863 --> 00:10:18,239 There are several different kind of variables inside this motor structure 125 00:10:20,031 --> 00:10:23,359 we just Define here are types 126 00:10:23,615 --> 00:10:29,759 And later on we will create a new user defined variables 127 00:10:30,015 --> 00:10:31,039 of This ttype 128 00:10:32,575 --> 00:10:34,367 so one type 129 00:10:35,391 --> 00:10:37,183 Maybe consist of 130 00:10:37,439 --> 00:10:42,303 One structured one variable or several different type of variables 131 00:10:46,143 --> 00:10:52,287 If you already use a different data types in classical Works in simatic 132 00:10:52,543 --> 00:10:54,591 you are familiar Description 133 00:10:54,847 --> 00:10:57,151 There are some Elementary data types 134 00:10:57,919 --> 00:11:01,503 Like Real or long and so on 135 00:11:02,271 --> 00:11:04,063 There are other Drive 136 00:11:04,319 --> 00:11:08,671 types structures in enumerators 137 00:11:09,951 --> 00:11:11,487 Just like this 138 00:11:12,511 --> 00:11:15,327 And structure like that 139 00:11:16,351 --> 00:11:22,495 and technology object or system data types already described in our 140 00:11:23,519 --> 00:11:24,543 CPUs 141 00:11:26,079 --> 00:11:27,359 So 142 00:11:28,127 --> 00:11:34,271 Global variables for global global constant and var global retain 143 00:11:39,903 --> 00:11:44,511 Decleration part of a program you see here 144 00:11:45,535 --> 00:11:50,399 In implementation and the program declaration type 145 00:11:52,191 --> 00:11:54,239 Local variables 146 00:11:55,519 --> 00:11:58,335 And temporary variables 147 00:11:58,591 --> 00:12:02,687 As local or local constants 148 00:12:03,199 --> 00:12:05,759 here is the Declaration section 149 00:12:07,551 --> 00:12:11,647 here Is the program section really 150 00:12:18,559 --> 00:12:24,703 so validity of variables unit left and unit right 151 00:12:24,959 --> 00:12:27,775 Two examples here 152 00:12:30,079 --> 00:12:33,407 you see here with different colors 153 00:12:36,479 --> 00:12:40,063 Global device variables here 154 00:12:41,343 --> 00:12:45,439 Is accessible from all of the other units 155 00:12:45,695 --> 00:12:47,743 Readable and writable 156 00:12:48,255 --> 00:12:54,399 You'll see here and the background some simotion device available 157 00:12:56,447 --> 00:13:02,079 on the unit left There's interface section and Global variables 158 00:13:03,103 --> 00:13:07,199 It's accessible by other units right 159 00:13:07,967 --> 00:13:10,783 The same way or vice versa 160 00:13:18,463 --> 00:13:21,791 If you are describing 161 00:13:22,047 --> 00:13:28,191 local variable Your program test and is has and what it is of usage of this variable 162 00:13:36,127 --> 00:13:42,271 If you're using a global variable in your implementation section 163 00:13:42,783 --> 00:13:44,319 And validity 164 00:13:44,575 --> 00:13:46,623 Is accessible from 165 00:13:47,135 --> 00:13:50,975 Program test 1 and program to test 2 166 00:13:51,743 --> 00:13:54,815 From inside out 167 00:13:59,935 --> 00:14:06,079 Global variables can we declerate in the interface or implementation part of the units 168 00:14:07,615 --> 00:14:13,759 local variables can only be used in exercise program in which they wrote declerated 169 00:14:14,783 --> 00:14:15,807 Like this 170 00:14:17,087 --> 00:14:23,231 These variables can either be monitored in symbol browser 171 00:14:23,487 --> 00:14:25,535 nor Accessed from 172 00:14:25,791 --> 00:14:28,863 Operator control and monitor devices 173 00:14:29,375 --> 00:14:35,519 Like HMI devices or OPC XML server 174 00:14:35,775 --> 00:14:39,359 locals Are the private property of the corresponding 175 00:14:39,615 --> 00:14:42,431 POU as it were 176 00:14:42,687 --> 00:14:43,711 So... 177 00:14:43,967 --> 00:14:50,111 If I want to use privates betable I have to do it here as locally 178 00:14:52,927 --> 00:14:59,071 next page initializing variables interface and 179 00:14:59,327 --> 00:15:01,375 Implementation section 180 00:15:02,399 --> 00:15:08,031 initialization on overrall resed or downloads 181 00:15:08,287 --> 00:15:12,383 Is possible with retain variables 182 00:15:13,663 --> 00:15:19,807 for Non retain or volatile variables initialization on 183 00:15:23,135 --> 00:15:26,463 power on and overall reset 184 00:15:26,975 --> 00:15:28,511 from stop mode to run mode as version 185 00:15:29,279 --> 00:15:33,119 from 4.2 is always done 186 00:15:35,679 --> 00:15:39,263 For retain it depends on your choice 187 00:15:39,775 --> 00:15:41,823 It's possible to do 188 00:15:42,591 --> 00:15:43,871 in download 189 00:15:44,127 --> 00:15:47,455 Or with overall reset 190 00:15:48,735 --> 00:15:49,759 Next thing 191 00:15:50,783 --> 00:15:53,599 For implementation section 192 00:15:53,855 --> 00:15:59,999 Initialization on overall reset and download possible for retained Global variables 193 00:16:03,583 --> 00:16:06,399 What is the same way for 194 00:16:07,167 --> 00:16:13,055 Other Global variables in implementation section what about the program insight? 195 00:16:15,103 --> 00:16:15,871 So 196 00:16:16,127 --> 00:16:20,991 For static program or function block 197 00:16:21,503 --> 00:16:23,295 local variables 198 00:16:23,551 --> 00:16:26,111 Initialization 199 00:16:26,367 --> 00:16:29,439 Will be done on start of tasks 200 00:16:29,951 --> 00:16:33,279 For example switch to stop to run 201 00:16:37,375 --> 00:16:43,519 and Temporary variables initialization on program called or function block call 202 00:16:43,775 --> 00:16:47,615 That's why the the variables are temporary 203 00:16:55,295 --> 00:16:57,343 Normally 204 00:16:57,599 --> 00:17:00,159 Inside the program section 205 00:17:00,671 --> 00:17:02,975 These are static variables 206 00:17:05,535 --> 00:17:11,679 they only reset to initial value is Task is running 207 00:17:12,447 --> 00:17:13,983 restarted 208 00:17:16,543 --> 00:17:17,311 Yeah 209 00:17:18,335 --> 00:17:23,455 in FB this variables are part of instance data 210 00:17:24,735 --> 00:17:30,367 Initialization depends upon variable type 211 00:17:31,135 --> 00:17:33,951 global retain or volatile which instance 212 00:17:40,351 --> 00:17:46,495 If I want to preserve my parameter or online data 213 00:17:46,751 --> 00:17:50,079 During CPU runtime 214 00:17:50,591 --> 00:17:53,151 Then I have to choose 215 00:17:53,919 --> 00:17:57,247 This global global retainer area 216 00:17:58,015 --> 00:18:00,063 when i 217 00:18:00,575 --> 00:18:06,719 want to choose to use static variable inside my programs or function blocks 218 00:18:06,975 --> 00:18:11,071 After task restart or CPU stopped run 219 00:18:11,327 --> 00:18:12,607 Even the data 220 00:18:13,119 --> 00:18:19,263 is static will be initialized that's an important 221 00:18:20,543 --> 00:18:26,687 Overview of the simotion data types are Elementary and 222 00:18:26,943 --> 00:18:29,759 Compounds or derived types 223 00:18:31,551 --> 00:18:33,087 As you can see 224 00:18:35,647 --> 00:18:40,767 So what kind of Elementary data types do we have 225 00:18:41,279 --> 00:18:43,071 keywords... 226 00:18:43,839 --> 00:18:49,983 bool byte word Integer and double integer types you will see here on the right 227 00:18:50,239 --> 00:18:51,775 Column... 228 00:18:52,031 --> 00:18:57,919 Real a long real as possible special we use 229 00:18:58,175 --> 00:19:04,319 For Action position value or parameters Long real 230 00:19:04,575 --> 00:19:07,647 Are memory is quite good enough 231 00:19:09,439 --> 00:19:10,719 Yep 232 00:19:11,999 --> 00:19:15,839 So array data type 233 00:19:16,095 --> 00:19:19,679 here type description 234 00:19:19,935 --> 00:19:22,239 A Is all right 235 00:19:23,007 --> 00:19:24,543 one dimentional 236 00:19:24,799 --> 00:19:27,359 1 to 6 of real time 237 00:19:28,895 --> 00:19:29,919 6 columns 238 00:19:30,175 --> 00:19:34,015 Matrix is an example type 239 00:19:34,271 --> 00:19:35,807 Consist of A 240 00:19:38,111 --> 00:19:44,255 That means array inside array and so we will describe two dimensional array 241 00:19:44,511 --> 00:19:47,839 and six columns here 242 00:19:49,119 --> 00:19:51,679 This is just for tpye description 243 00:19:52,191 --> 00:19:57,055 That's it I'm going to create a user variable 244 00:19:57,823 --> 00:19:59,871 Static variable here 245 00:20:00,639 --> 00:20:04,735 A on the score one B on the score 1 and on the score one 246 00:20:06,271 --> 00:20:09,087 Type of A that means 247 00:20:11,391 --> 00:20:14,975 A1 is variable of 1 dimentional array data type 248 00:20:17,535 --> 00:20:21,375 so We are using 249 00:20:21,887 --> 00:20:28,031 elementary data types or combine data types to create new data types 250 00:20:28,543 --> 00:20:29,311 And 251 00:20:29,567 --> 00:20:31,615 Define deliverables 252 00:20:32,383 --> 00:20:33,663 So that way 253 00:20:36,479 --> 00:20:40,831 character strings in structure text 254 00:20:41,343 --> 00:20:44,159 data type with a maximum length of 255 00:20:44,415 --> 00:20:47,231 254 characters 256 00:20:48,255 --> 00:20:52,095 Variable declaration is here 257 00:20:52,351 --> 00:20:54,143 If you don't use 258 00:20:54,399 --> 00:20:59,775 This option the maximum length with be 80 characters as default 259 00:21:00,031 --> 00:21:04,127 You can set a maximum length under 260 00:21:04,383 --> 00:21:07,455 For example 120 characters is possible 261 00:21:08,223 --> 00:21:14,111 An example assignments you see here as his name equals 262 00:21:14,623 --> 00:21:15,647 Transporter 263 00:21:17,184 --> 00:21:19,232 So with string 264 00:21:19,744 --> 00:21:21,536 Characters and variables 265 00:21:21,792 --> 00:21:27,936 It's possible to use compression operations like greater or 266 00:21:28,192 --> 00:21:33,056 Let's equal and so on string functions 267 00:21:33,312 --> 00:21:37,152 located in Library as character streams 268 00:21:37,408 --> 00:21:38,432 Concat 269 00:21:38,944 --> 00:21:41,504 delete find replace len 270 00:21:41,760 --> 00:21:44,064 These are the universal keyboards 271 00:21:44,576 --> 00:21:47,904 I guess your familiar already 272 00:21:48,928 --> 00:21:52,256 An assignment to byte 273 00:21:52,512 --> 00:21:56,352 Bit variables is possible by 274 00:21:56,864 --> 00:21:59,424 Of course 20 275 00:21:59,680 --> 00:22:01,472 Which connected here 276 00:22:02,752 --> 00:22:06,336 You can get the ASCII codes of the character as bytes 277 00:22:07,104 --> 00:22:08,640 Or vice versa 278 00:22:09,408 --> 00:22:13,248 Conversion from or to 279 00:22:13,760 --> 00:22:17,856 So integer real long real is possible 280 00:22:19,392 --> 00:22:20,672 Yep 281 00:22:23,744 --> 00:22:25,536 there are some notes 282 00:22:25,792 --> 00:22:28,864 You should read later on 283 00:22:32,192 --> 00:22:35,776 Another data type is structure 284 00:22:36,544 --> 00:22:41,152 For example in there is an electrical motor 285 00:22:43,456 --> 00:22:49,600 Grouping of components of different data types in the structure is possible 286 00:22:51,648 --> 00:22:54,464 here see an example 287 00:22:55,232 --> 00:22:58,816 UDT definition as type 288 00:23:00,864 --> 00:23:02,656 we will 289 00:23:03,168 --> 00:23:05,472 Describe our structure 290 00:23:06,240 --> 00:23:09,312 isside type definition motor 291 00:23:10,336 --> 00:23:16,480 Consists of set point speed actual speed enable and fault if this case 292 00:23:16,736 --> 00:23:22,880 After that is second step we will use this user-defined data type 293 00:23:23,136 --> 00:23:26,464 Motor 1 is a motor 294 00:23:26,976 --> 00:23:31,840 and we can access subtitles like this 295 00:23:32,352 --> 00:23:35,168 Moto R1. 296 00:23:36,448 --> 00:23:39,520 setpoint speed 100.0 297 00:23:39,776 --> 00:23:40,800 for write 298 00:23:41,312 --> 00:23:44,896 data of structure and so on... 299 00:23:51,552 --> 00:23:52,832 Yep 300 00:23:53,344 --> 00:23:59,488 data type enumerator is limited number of identifier 301 00:23:59,744 --> 00:24:02,048 Declaration of axis 302 00:24:06,656 --> 00:24:12,288 For instance. Describe a situation or state graph of a guards 303 00:24:13,056 --> 00:24:19,200 1 means opening 2 mins open 3 Means closing + 0 means it is closed 304 00:24:19,456 --> 00:24:22,016 At this case 305 00:24:24,832 --> 00:24:28,928 Type definition is like this grass States 306 00:24:29,184 --> 00:24:32,000 Coolest - 1 opening 307 00:24:32,256 --> 00:24:33,536 Is 2 308 00:24:35,840 --> 00:24:37,376 Open is 0 309 00:24:38,912 --> 00:24:41,216 Closing is 310 00:24:44,032 --> 00:24:45,312 1 perhaps 311 00:24:45,568 --> 00:24:47,360 lets try 312 00:24:48,384 --> 00:24:51,200 you can read.... 313 00:24:55,040 --> 00:25:01,184 Technology object data types structure and function provided by simotion 314 00:25:01,440 --> 00:25:03,744 cam type drive axis... 315 00:25:04,768 --> 00:25:08,608 It's like a class structure 316 00:25:11,424 --> 00:25:15,264 You can use your own variable 317 00:25:16,032 --> 00:25:17,056 Here 318 00:25:18,080 --> 00:25:20,640 Define as pos axis 319 00:25:20,896 --> 00:25:23,200 Make an 320 00:25:23,456 --> 00:25:26,016 You know Arrangements 321 00:25:26,272 --> 00:25:31,904 Long as you're my axis variable equals axis one 322 00:25:32,672 --> 00:25:37,792 You can use later on in your program available 323 00:25:40,864 --> 00:25:41,888 So... 324 00:25:42,144 --> 00:25:48,288 TOs structure and functions provided by individual technology 325 00:25:48,544 --> 00:25:49,312 packages 326 00:25:50,080 --> 00:25:56,224 Yep simotion provides as the following TOs Drive access 327 00:25:56,480 --> 00:26:00,832 pos axes following axes 328 00:26:01,088 --> 00:26:06,720 measuring input-output system encoder temperature controller 329 00:26:06,976 --> 00:26:09,792 And an object. 330 00:26:12,864 --> 00:26:17,728 This convert for example 331 00:26:17,984 --> 00:26:20,544 Position axis 332 00:26:20,800 --> 00:26:23,872 To following axis in our program 333 00:26:24,640 --> 00:26:26,688 As an input 334 00:26:28,224 --> 00:26:32,576 Statement part of a program see here 335 00:26:32,832 --> 00:26:35,392 The statement that program code 336 00:26:36,160 --> 00:26:41,280 Equal length * width blah blah blah 337 00:26:42,560 --> 00:26:48,704 This isn't right axis here the east branch controls 338 00:26:48,960 --> 00:26:51,264 and so on... 339 00:26:54,336 --> 00:27:00,480 Types of a statement is value assigment control statement and subroutine execution 340 00:27:00,736 --> 00:27:05,600 Or system function calls looks like this 341 00:27:06,368 --> 00:27:08,672 ST 342 00:27:09,952 --> 00:27:16,096 You'll see here the expressions and operators and Operands in structure text 343 00:27:17,120 --> 00:27:20,704 mathemathical or relational operators 344 00:27:21,984 --> 00:27:25,056 variables 345 00:27:25,568 --> 00:27:28,896 ... 346 00:27:31,456 --> 00:27:36,832 assigment will be looks like in structure text 347 00:27:39,392 --> 00:27:41,696 structure Assignment 348 00:27:43,744 --> 00:27:48,352 It's right to assignment entire structure assignment is possible 349 00:27:49,120 --> 00:27:55,264 Or component assignment is possible entire array assignment is possible 350 00:27:55,776 --> 00:28:01,152 There's no need to use another function like block move 351 00:28:01,920 --> 00:28:04,992 or array copy in simatic world 352 00:28:06,272 --> 00:28:12,416 So that's why it's sometimes harder to convert your program from simotion 353 00:28:12,672 --> 00:28:13,952 to simatic 354 00:28:17,280 --> 00:28:23,424 Access IOs and process images you see here that's an identifier 355 00:28:23,680 --> 00:28:25,728 it is possible in program 356 00:28:25,984 --> 00:28:30,336 but Normally view of Define are symbols in table 357 00:28:35,456 --> 00:28:41,600 There's some input image table and there is an output image table 358 00:28:44,416 --> 00:28:48,000 And there's another small table 359 00:28:48,512 --> 00:28:51,072 named Process image input 360 00:28:51,840 --> 00:28:57,984 Process image Inputs or user defined process images 361 00:29:00,544 --> 00:29:06,176 Normally this small tables refreshed by System 362 00:29:06,432 --> 00:29:08,992 At the beginning of the cycle 363 00:29:09,248 --> 00:29:13,600 for inputs at the end of the cycle for outputs 364 00:29:13,856 --> 00:29:20,000 So if you want to get the news 365 00:29:20,256 --> 00:29:24,096 Level or logic step of an input 366 00:29:24,864 --> 00:29:27,168 You should use 367 00:29:27,680 --> 00:29:31,520 Process image byte instead of 368 00:29:32,032 --> 00:29:33,056 This 369 00:29:33,312 --> 00:29:34,848 Deceleration 370 00:29:39,456 --> 00:29:40,480 So 371 00:29:40,736 --> 00:29:46,880 Logical address space for simotion Drive based system 372 00:29:47,392 --> 00:29:49,440 That's quite good enough 373 00:29:51,744 --> 00:29:55,840 For other Hardware platforms it's limited weeks 374 00:29:56,096 --> 00:29:57,376 4 kilobytes 375 00:30:02,752 --> 00:30:08,896 Access to individual bits with the permit language extension compile option 376 00:30:11,712 --> 00:30:16,320 But now we see how do we use this function in our program 377 00:30:17,344 --> 00:30:21,696 we will described here my results my anybit 378 00:30:21,952 --> 00:30:23,744 And make it definition 379 00:30:24,512 --> 00:30:29,888 After that if I want to get a bit from 380 00:30:30,656 --> 00:30:33,216 a byte 381 00:30:33,472 --> 00:30:39,360 Any bits but I will answer here the bit no as 5 382 00:30:39,872 --> 00:30:41,664 This is one way to do that 383 00:30:42,432 --> 00:30:47,808 without language Extinction you will see here 384 00:30:50,112 --> 00:30:52,416 easily byte variable dot 5 385 00:30:52,928 --> 00:30:56,768 Results a bit status with language Extension 386 00:30:57,792 --> 00:30:59,072 Is possible 387 00:31:00,864 --> 00:31:07,008 and for setting bit use this function or language extension here 388 00:31:07,264 --> 00:31:09,824 That is also toggle bit functions 389 00:31:10,080 --> 00:31:14,432 Is possible to do with xor gate 390 00:31:15,456 --> 00:31:19,808 as scout 4.1 391 00:31:20,320 --> 00:31:25,184 It is possible to use user-friendly 392 00:31:25,696 --> 00:31:26,464 Axis 393 00:31:26,720 --> 00:31:32,864 of Individual bits of advice or words of double word is possible 394 00:31:34,144 --> 00:31:37,728 next page 395 00:31:37,984 --> 00:31:41,824 See the control statement if else case 396 00:31:42,080 --> 00:31:45,920 it Looks like this in our user program 397 00:31:46,176 --> 00:31:52,320 else fi and this and Case commission is similar to Pascal 398 00:31:52,576 --> 00:31:56,672 Programming language so it's look like in MCC 399 00:31:57,440 --> 00:32:03,584 This is the same thing in structure text 400 00:32:04,608 --> 00:32:10,752 Control statements for vwhile repeats here example 401 00:32:11,008 --> 00:32:12,032 usage 402 00:32:23,296 --> 00:32:26,880 What's the difference between while and repeat? 403 00:32:27,904 --> 00:32:33,536 In while loop program interpolator is running from up to down 404 00:32:33,792 --> 00:32:39,936 If the condition is not met that you skip the statements here then your 405 00:32:40,192 --> 00:32:40,960 commands 406 00:32:41,216 --> 00:32:45,568 For example set the alarm bit is not executed 407 00:32:46,592 --> 00:32:48,384 It's a repeat Loop 408 00:32:48,640 --> 00:32:51,200 It was see here some statements 409 00:32:52,224 --> 00:32:58,368 commands will be Executives here after that the condition will be checked 410 00:32:59,904 --> 00:33:02,464 If the condition is not met 411 00:33:03,488 --> 00:33:06,048 The program to continue to Next Step 412 00:33:07,584 --> 00:33:12,448 At least once your output is set here 413 00:33:12,960 --> 00:33:17,312 Because you check the condition after your statement 414 00:33:20,384 --> 00:33:23,968 control statements exit and return 415 00:33:24,224 --> 00:33:30,368 we will used this statement in or Loops for example 416 00:33:31,136 --> 00:33:35,232 If input 1.1 is through the exit Loop 417 00:33:35,488 --> 00:33:37,024 This is the endless loop 418 00:33:38,304 --> 00:33:40,864 User return in functions 419 00:33:41,376 --> 00:33:47,520 is true then return from function to 420 00:33:48,288 --> 00:33:52,640 Points or line were it called 421 00:33:55,200 --> 00:33:59,808 we will not execute next steps in this function 422 00:34:03,136 --> 00:34:04,672 Next page 423 00:34:05,952 --> 00:34:09,536 Go to and wait for conditional statement 424 00:34:12,864 --> 00:34:14,400 with go to 425 00:34:14,912 --> 00:34:21,056 we Create several labels in different places in our program 426 00:34:21,312 --> 00:34:23,360 After that 427 00:34:24,128 --> 00:34:27,968 It's possible to use go to keyword for jump 428 00:34:28,736 --> 00:34:31,808 wait for condition 429 00:34:33,088 --> 00:34:35,648 we will call with an expression 430 00:34:36,160 --> 00:34:39,232 if Expression is true 431 00:34:39,744 --> 00:34:43,072 We will execute some statement 432 00:34:52,288 --> 00:34:54,080 So comments 433 00:34:55,104 --> 00:35:00,480 Breaking news line come with double / or we may use block commands 434 00:35:01,248 --> 00:35:02,528 With that way 435 00:35:06,880 --> 00:35:11,232 contorl the compilation with preprocessor 436 00:35:11,488 --> 00:35:14,560 Replace the names in ST source 437 00:35:15,072 --> 00:35:20,192 Yeah we change is defined and undefined identifiers 438 00:35:21,728 --> 00:35:23,520 for compilation 439 00:35:24,800 --> 00:35:27,872 It's another useful feature 440 00:35:30,688 --> 00:35:32,224 you see 441 00:35:33,504 --> 00:35:38,880 And example of use preprocessor 442 00:35:40,160 --> 00:35:46,304 An example program code you see here function block definition interface Global variable 443 00:35:46,560 --> 00:35:50,400 After that your Define my Define 444 00:35:50,656 --> 00:35:54,240 global var 445 00:35:55,008 --> 00:36:00,640 At the implementation section there's a function function block 446 00:36:01,664 --> 00:36:02,688 So 447 00:36:02,944 --> 00:36:07,296 Define assignment var 448 00:36:07,808 --> 00:36:11,136 And it's called the 449 00:36:11,648 --> 00:36:13,952 my define 450 00:36:14,720 --> 00:36:19,328 afterf the preposition 451 00:36:20,096 --> 00:36:26,240 Or assignment to f g 1 + 1 452 00:36:26,496 --> 00:36:29,312 Not replaced here 453 00:36:32,128 --> 00:36:36,224 So I special cases it reduces time 454 00:36:36,992 --> 00:36:40,064 but as 455 00:36:40,320 --> 00:36:43,392 an Disadvantage your program will be 456 00:36:43,648 --> 00:36:46,464 little bit complicated for read 457 00:36:48,768 --> 00:36:54,912 soTesting testing programs program status symbol browser for monitoring and 458 00:36:55,168 --> 00:36:57,472 Controlling monitor watch table 459 00:36:57,984 --> 00:37:00,544 trace tool 460 00:37:01,568 --> 00:37:03,616 How do you do that? 461 00:37:04,640 --> 00:37:10,784 So I'm Target system or right-click to CPU operating mode 462 00:37:11,040 --> 00:37:12,832 It's just switch between modes 463 00:37:15,648 --> 00:37:21,792 For test program and switch on the program status on St sides it looks like this 464 00:37:23,840 --> 00:37:25,632 There's a program status 465 00:37:25,888 --> 00:37:27,936 looks like some 466 00:37:28,704 --> 00:37:31,008 Glasses 467 00:37:32,800 --> 00:37:35,104 And there isn't stop monitoring 468 00:37:36,640 --> 00:37:37,664 Button 469 00:37:37,920 --> 00:37:40,992 Is possible to force an update variables 470 00:37:42,272 --> 00:37:48,416 This is the monitoring screen divided as vertically on the right 471 00:37:48,672 --> 00:37:54,304 side see status of wearables 472 00:37:55,328 --> 00:37:57,120 If else ase 473 00:37:58,656 --> 00:38:01,216 You'll see your counter variable is 474 00:38:02,496 --> 00:38:05,312 Less of 500 that's why 475 00:38:05,568 --> 00:38:10,176 You see this site and as condition is not met 476 00:38:10,688 --> 00:38:12,224 You'll see here 477 00:38:12,736 --> 00:38:14,016 The question marks 478 00:38:14,272 --> 00:38:15,552 That's the reason 479 00:38:21,184 --> 00:38:27,328 Normal structure text we will use symbol browser to monitor variables 480 00:38:28,352 --> 00:38:29,632 Together 481 00:38:32,704 --> 00:38:36,800 It's also possible to add to watch table at monitor 482 00:38:37,568 --> 00:38:40,896 The group up or user variables 483 00:38:42,944 --> 00:38:49,088 There are some new functions in ST editor as of firmware version 484 00:38:49,344 --> 00:38:50,624 4.2 485 00:38:51,648 --> 00:38:56,512 Context menu with comments for copy and paste lights 486 00:38:56,768 --> 00:38:58,304 Changing the view 487 00:38:59,328 --> 00:39:01,888 Go to bookmarks startup block 488 00:39:02,144 --> 00:39:03,424 and so on... 489 00:39:03,936 --> 00:39:06,752 Support for Split windows 490 00:39:07,008 --> 00:39:08,800 possible to open 491 00:39:09,056 --> 00:39:12,384 Two different page St units 492 00:39:12,640 --> 00:39:15,200 Sequence generator 493 00:39:15,456 --> 00:39:20,064 Autocomplete with control + space 494 00:39:23,648 --> 00:39:27,744 Yeah you're a useful function you said it 495 00:39:28,000 --> 00:39:30,048 Index of an array 496 00:39:31,328 --> 00:39:33,120 click 497 00:39:33,888 --> 00:39:38,752 Or you just enter 498 00:39:39,520 --> 00:39:42,080 You 499 00:39:42,336 --> 00:39:48,480 alt key Press Ctrl shift on S7 buttons than you see it's automatically arranged 500 00:39:53,344 --> 00:39:55,904 You can do it on the other side 501 00:39:56,672 --> 00:39:58,464 For instance 502 00:39:59,744 --> 00:40:04,096 Set column by column width of alt key and mouse 503 00:40:05,376 --> 00:40:10,752 After you press Ctrl + shift key and 504 00:40:11,520 --> 00:40:16,640 Function 7 together you see on the right side 505 00:40:18,176 --> 00:40:19,968 value are arranged 506 00:40:25,600 --> 00:40:31,744 Setting breakpoints structure text is can only be used in program 507 00:40:32,000 --> 00:40:34,560 Function block and function 508 00:40:35,328 --> 00:40:38,656 And for procedure 509 00:40:40,960 --> 00:40:42,752 You have to set up debug mode 510 00:40:43,008 --> 00:40:48,896 And specify debug set breakpoints specified equipment 511 00:40:49,152 --> 00:40:51,456 Activate breakpoints 512 00:40:51,968 --> 00:40:57,344 At last it use variable status to monitor contents of local variables 513 00:40:59,648 --> 00:41:04,256 So you can set breakpoints within a program source 514 00:41:04,512 --> 00:41:07,072 It's this ST source whatever 515 00:41:07,840 --> 00:41:10,656 The preconditions are here 516 00:41:12,704 --> 00:41:14,240 already read 517 00:41:20,384 --> 00:41:23,200 so see debug task group 518 00:41:26,784 --> 00:41:28,832 Yeah 519 00:41:30,112 --> 00:41:36,000 First unit to right click and change operating mode to debug mode 520 00:41:36,256 --> 00:41:38,304 accept safety notes 521 00:41:40,096 --> 00:41:43,936 Okay program source is inconsistent has been changed 522 00:41:46,240 --> 00:41:48,032 Okay 523 00:41:49,056 --> 00:41:52,384 we changed something yes 524 00:41:52,895 --> 00:41:54,687 Let's save and compile 525 00:41:57,247 --> 00:42:01,599 You're offline and online program must be 526 00:42:04,927 --> 00:42:11,071 Same for debug your program and use the brakepoints 527 00:42:13,887 --> 00:42:17,215 When I click right 528 00:42:17,471 --> 00:42:21,055 It's now activated about test group and debug table 529 00:42:21,311 --> 00:42:27,455 For debug test group assign some of my tasks 530 00:42:28,223 --> 00:42:30,527 Which task of CPU should be stopped? 531 00:42:30,783 --> 00:42:32,063 When did break point? 532 00:42:32,319 --> 00:42:33,343 Is reached 533 00:42:33,599 --> 00:42:38,975 I'm going to use motion task one for instance. 534 00:42:42,047 --> 00:42:46,399 You can Define your debug table 535 00:42:47,167 --> 00:42:49,471 It's manage your break points 536 00:42:50,495 --> 00:42:55,103 I will group open my motion test motion program one 537 00:43:02,783 --> 00:43:07,135 You'll see here some basic programs 538 00:43:07,391 --> 00:43:09,439 And if the toolbar 539 00:43:12,255 --> 00:43:14,047 there are some ready to use buttons 540 00:43:15,583 --> 00:43:19,935 set Remove brake lines at this case I want at the breakpoint 541 00:43:21,215 --> 00:43:22,495 just 1 click 542 00:43:24,031 --> 00:43:30,175 If I click again it would be removed and next thing activate deactivate is breakpoint 543 00:43:31,199 --> 00:43:37,343 Maybe there are a lot of break points but you don't want to activate 544 00:43:37,855 --> 00:43:40,159 Next cycle or next try 545 00:43:41,183 --> 00:43:43,231 when I click this 546 00:43:44,255 --> 00:43:47,583 It's activated with filled with red 547 00:43:53,215 --> 00:43:55,007 When I go 548 00:43:55,263 --> 00:43:59,359 Yeah program statistics and monitor the variables 549 00:43:59,615 --> 00:44:01,151 And I double Click 550 00:44:02,175 --> 00:44:03,199 Here 551 00:44:04,223 --> 00:44:10,367 It's activated by the debug mode is working and break point reached 552 00:44:14,463 --> 00:44:17,279 at the mean time maybe you want to 553 00:44:17,791 --> 00:44:22,655 go device diagnostics at See on task manager 554 00:44:22,911 --> 00:44:27,775 You'll see here task is running but there's and Brake active 555 00:44:32,383 --> 00:44:34,687 If I could it again 556 00:44:35,455 --> 00:44:37,759 Breakpoint will be deactivated 557 00:44:41,599 --> 00:44:45,183 It's possible to edit the call path 558 00:44:46,719 --> 00:44:50,559 Which property is used for that preference 559 00:44:51,583 --> 00:44:57,727 I called this program from more than one but for function blocks you 560 00:44:57,983 --> 00:45:02,335 You have to describe it here to monitor 561 00:45:02,847 --> 00:45:06,175 Current points is important 562 00:45:08,735 --> 00:45:11,551 Activate all breakpoints 563 00:45:11,807 --> 00:45:17,951 Of the active POU you if there are five or six breakpoints and when you do 564 00:45:18,207 --> 00:45:22,815 Don't want to waste your time and activate all it's possible 565 00:45:23,327 --> 00:45:24,607 And that activates 566 00:45:25,375 --> 00:45:27,935 delete all breakpoints 567 00:45:29,215 --> 00:45:30,495 debug table 568 00:45:31,263 --> 00:45:32,543 here 569 00:45:33,055 --> 00:45:39,199 You'll see all of the breakpoints in your table you can just like activate deactivate or delete 570 00:45:40,991 --> 00:45:44,831 Display the call stack 571 00:45:45,599 --> 00:45:51,487 You can debug your call stack here breakpoint is activated everyone 572 00:45:53,023 --> 00:45:58,399 you can select 573 00:45:58,655 --> 00:46:02,239 Maybe every time or maybe ever 574 00:46:02,751 --> 00:46:04,543 20 run 575 00:46:05,311 --> 00:46:06,847 is possible 576 00:46:11,711 --> 00:46:13,759 then Our program is broken 577 00:46:15,295 --> 00:46:17,087 If you want to continue 578 00:46:17,343 --> 00:46:19,647 You have to keep the continiue button 579 00:46:20,415 --> 00:46:21,439 So 580 00:46:21,695 --> 00:46:24,255 In that case 581 00:46:24,767 --> 00:46:27,839 Its now running 582 00:46:28,607 --> 00:46:30,911 Executing our comments 583 00:46:31,167 --> 00:46:32,447 Basically 584 00:46:33,471 --> 00:46:36,799 So let's continue with notes 585 00:46:42,687 --> 00:46:43,967 Yep 586 00:46:55,231 --> 00:47:01,375 If you said it's your old tasks note that all outputs will be deactivated 587 00:47:02,399 --> 00:47:04,447 when break point is reached 588 00:47:05,215 --> 00:47:11,359 Be careful if you are energizing some contractors or 589 00:47:11,615 --> 00:47:14,687 Your outputs connected to 590 00:47:15,711 --> 00:47:18,783 Some valves you need to be careful 591 00:47:19,039 --> 00:47:21,855 during debug 592 00:47:23,135 --> 00:47:28,255 Next page setting breakpoints in St source file 593 00:47:29,279 --> 00:47:34,655 Actually is the same way you just said it to your online and use the 594 00:47:34,911 --> 00:47:38,751 Same buttons located in your toolbar 595 00:47:40,799 --> 00:47:44,639 then you specify the call path 596 00:47:48,991 --> 00:47:54,111 Then you can activate deactivate or delete your breakpoints 597 00:47:56,159 --> 00:47:58,207 You can use keyboard shortcuts 598 00:48:02,815 --> 00:48:06,143 So it's available status 599 00:48:07,167 --> 00:48:08,447 Below the screen 600 00:48:14,335 --> 00:48:16,639 You can status your variable 601 00:48:17,919 --> 00:48:20,991 After program stops 602 00:48:25,087 --> 00:48:29,183 You can use breakpoint and program status together 603 00:48:31,231 --> 00:48:33,023 to see current 604 00:48:34,303 --> 00:48:35,327 values 605 00:48:39,935 --> 00:48:46,079 You can record with Device trace or your firmware 606 00:48:46,335 --> 00:48:49,151 if is higher than 607 00:48:49,407 --> 00:48:54,271 4.2 record variables with system trace 608 00:49:05,023 --> 00:49:09,375 here you see device trace and system Trace 609 00:49:13,983 --> 00:49:19,615 Unlimited isochron endless trace Servo Factor 2 610 00:49:21,151 --> 00:49:23,455 Then you should 611 00:49:24,223 --> 00:49:27,295 Use maybe the ring buffer okay 612 00:49:30,111 --> 00:49:32,415 Let's add some variable here 613 00:49:38,303 --> 00:49:43,679 Some technology objects variable 614 00:49:52,895 --> 00:49:54,175 or... 615 00:49:56,991 --> 00:49:59,807 Or positioning States 616 00:50:09,279 --> 00:50:13,119 yes... 617 00:50:16,703 --> 00:50:21,567 It's possible to add until 128 618 00:50:21,823 --> 00:50:24,127 i need downloads 619 00:50:24,383 --> 00:50:26,943 Parameterization available 620 00:50:27,199 --> 00:50:33,343 System trace cannot be used as only device simultaneously okay alright 621 00:50:33,599 --> 00:50:34,879 Yes 622 00:50:39,743 --> 00:50:43,071 System Trace parameterization 623 00:50:43,327 --> 00:50:45,119 Is that start 624 00:51:00,223 --> 00:51:01,503 Stop 625 00:51:04,831 --> 00:51:09,183 You can change your the active curve standtstill monitoring 626 00:51:12,511 --> 00:51:14,815 For the face of position monitoring 627 00:51:25,823 --> 00:51:31,711 It's possible to select the other values 628 00:51:34,015 --> 00:51:36,063 here with 629 00:51:36,319 --> 00:51:38,111 This way 630 00:51:39,135 --> 00:51:40,671 Okay 631 00:51:46,303 --> 00:51:52,447 a system trace is support data used to report up 128 632 00:51:52,703 --> 00:51:56,031 From multiple simotion controllers 633 00:51:56,287 --> 00:51:59,103 Together with profinet IRT 634 00:51:59,871 --> 00:52:05,247 At the same trigger criteria as for 635 00:52:05,759 --> 00:52:11,903 Individual device Trace are available or shooting of a specific volume 636 00:52:12,159 --> 00:52:13,695 and so on... 637 00:52:14,463 --> 00:52:20,607 Corporate system such as printing process with multiple motor controllers and 638 00:52:20,863 --> 00:52:27,007 sync Operation across all devices this is signefficiently reduces 639 00:52:27,263 --> 00:52:31,359 Commission also service requirements 640 00:52:31,615 --> 00:52:35,711 So the systems trace is in advance 641 00:52:37,503 --> 00:52:38,783 Next page 642 00:52:39,295 --> 00:52:43,391 Diagnostics with the to trace 643 00:52:43,903 --> 00:52:50,047 you will see here technology object trace we're already used to set up 644 00:52:51,071 --> 00:52:57,215 Debug our technology objects comments or configuration data change 645 00:52:57,471 --> 00:53:02,847 Or system readable change it is also possible 646 00:53:03,103 --> 00:53:09,247 Actually the firmware version 4.2 it's was 647 00:53:10,015 --> 00:53:11,295 Radical game changer 648 00:53:12,063 --> 00:53:18,207 Version and there are a lot of usable features 649 00:53:18,463 --> 00:53:20,255 Just like this 650 00:53:26,399 --> 00:53:28,191 That's why 651 00:53:28,703 --> 00:53:33,823 a lot of Details about this version added 652 00:53:34,847 --> 00:53:38,175 later on so... 653 00:53:40,479 --> 00:53:46,623 now we have completed our lecture notes for programming with structure 654 00:53:51,743 --> 00:53:54,559 I will switch back to 655 00:53:54,815 --> 00:53:57,375 simotion projects 656 00:53:58,655 --> 00:54:01,471 you will see here or 657 00:54:01,727 --> 00:54:07,871 Empty almost empty ST you can Define here some types 658 00:54:08,127 --> 00:54:13,503 Structures you can Define your programs here 659 00:54:16,319 --> 00:54:22,463 For instance i say empty program 1 that means I will call this program 660 00:54:22,719 --> 00:54:28,863 From motion task i will Define here in interface 661 00:54:30,399 --> 00:54:32,447 Exportable 662 00:54:34,239 --> 00:54:38,847 back program on me so I recorded for background 663 00:54:41,663 --> 00:54:44,991 IPO programming means 664 00:54:45,247 --> 00:54:48,575 i will call this program from IPO task 665 00:54:49,343 --> 00:54:55,487 And I have to Define my program and write some code 666 00:54:55,743 --> 00:54:58,815 Implementation section 667 00:54:59,071 --> 00:55:01,119 Here it should be 668 00:55:01,375 --> 00:55:02,655 Like this 669 00:55:02,911 --> 00:55:04,447 end program 670 00:55:07,263 --> 00:55:09,311 Yep. 671 00:55:16,223 --> 00:55:19,551 This is our empty program 672 00:55:19,807 --> 00:55:22,111 This is an empty program 673 00:55:22,367 --> 00:55:26,719 This is an empty program let's use preprocessor 674 00:55:29,279 --> 00:55:31,071 no error no warning 675 00:55:32,095 --> 00:55:38,239 Let's add some variables and 676 00:55:38,495 --> 00:55:39,519 variable 677 00:55:40,543 --> 00:55:43,103 variable temp 678 00:55:43,359 --> 00:55:45,407 Available 679 00:55:47,967 --> 00:55:52,063 static so... 680 00:55:55,391 --> 00:56:00,255 function block definition is similar 681 00:56:01,535 --> 00:56:02,815 Let's see 682 00:56:03,071 --> 00:56:05,631 If the test 1 683 00:56:12,799 --> 00:56:13,823 Yo 684 00:56:16,127 --> 00:56:18,431 FB test 1 685 00:56:21,759 --> 00:56:23,039 were 686 00:56:23,807 --> 00:56:25,599 input 687 00:56:25,855 --> 00:56:31,487 varible 688 00:56:31,743 --> 00:56:33,535 outputs 689 00:56:33,791 --> 00:56:35,327 varible in out 690 00:56:35,583 --> 00:56:37,375 Is possible 691 00:56:38,655 --> 00:56:44,287 Another thing is available temp is possible 692 00:56:50,943 --> 00:56:51,967 Okay 693 00:56:55,039 --> 00:57:01,183 Accept and compile my program as you can see here 694 00:57:01,439 --> 00:57:06,559 That are three different programs and 1 function block 695 00:57:06,815 --> 00:57:08,351 if i click here 696 00:57:09,119 --> 00:57:12,447 the inputs and outputs 697 00:57:18,591 --> 00:57:24,735 object browser that are some items it looks like the classical CODESYS 698 00:57:26,015 --> 00:57:28,063 based editor 699 00:57:28,575 --> 00:57:32,671 You'll see standart Functionality 700 00:57:33,183 --> 00:57:35,743 Which device package 701 00:57:35,999 --> 00:57:42,143 What is the units POUs Global variables 702 00:57:42,911 --> 00:57:47,007 If you're familiar with CODESYS is based 703 00:57:47,519 --> 00:57:50,591 Devices or you're using codesys 704 00:57:51,615 --> 00:57:54,431 It's really similar to you 705 00:57:57,503 --> 00:58:03,647 I told you I think it's a good idea to make some exercises 706 00:58:03,903 --> 00:58:10,047 Create a new St unit and write your own programs 707 00:58:10,303 --> 00:58:15,423 Execution system with different tasks and see 708 00:58:16,447 --> 00:58:18,495 with traces 709 00:58:18,751 --> 00:58:20,287 What's going on? 710 00:58:20,543 --> 00:58:23,615 Set some breakpoints 711 00:58:23,871 --> 00:58:26,687 in your program in structure text 712 00:58:27,967 --> 00:58:29,759 Let's try in run mode 713 00:58:35,135 --> 00:58:41,279 We are created in units when you are working with structure text 714 00:58:42,047 --> 00:58:44,351 It's 715 00:58:44,607 --> 00:58:47,167 More 716 00:58:47,423 --> 00:58:50,751 Possible to make a download in run 717 00:58:51,007 --> 00:58:56,127 when you compare program in MCC 718 00:58:56,383 --> 00:59:00,735 That's why it still has an advantage at this point 719 00:59:02,527 --> 00:59:08,671 This is another reason why we choose the program which structure text it's basic 720 00:59:08,927 --> 00:59:15,071 Easy to copy and paste and it has some advantages 721 00:59:15,327 --> 00:59:16,351 So ... 722 00:59:16,863 --> 00:59:23,007 We have our program and to program 1 let's set a breakpoint here 723 00:59:23,519 --> 00:59:25,567 for program 1 724 00:59:27,103 --> 00:59:33,247 There's no code I have to add some code here or make an assignment variable 725 00:59:37,343 --> 00:59:40,671 A variable as integer 726 00:59:41,695 --> 00:59:43,487 Let's say 727 00:59:48,095 --> 00:59:52,447 make and assignment is Equals 728 00:59:52,703 --> 00:59:55,007 15 729 01:00:07,039 --> 01:00:13,183 So we didn't called our program and MT program 1 730 01:00:18,047 --> 01:00:21,375 Maybe we should call First 731 01:00:31,615 --> 01:00:32,639 Okay 732 01:00:49,279 --> 01:00:53,119 Let's say remove breakpoints 733 01:01:06,175 --> 01:01:10,527 No that's a breakpoint here 734 01:01:11,807 --> 01:01:14,623 Let's take our glasses to look 735 01:01:15,391 --> 01:01:21,535 Program did not want to here your right is not assigned to any task 736 01:01:22,303 --> 01:01:25,631 Let's assigned to a task 737 01:01:29,471 --> 01:01:31,007 Backgrounds 738 01:01:33,823 --> 01:01:39,711 back program accept close 739 01:01:40,735 --> 01:01:43,039 Downloading in run 740 01:01:43,295 --> 01:01:44,319 Let's try 741 01:01:49,951 --> 01:01:53,279 How to change the execution system so 742 01:01:53,535 --> 01:01:57,631 I have to stop first then download again 743 01:02:00,447 --> 01:02:03,263 Set an alarm 744 01:02:03,519 --> 01:02:07,103 I want to work with my back program 745 01:02:09,919 --> 01:02:11,199 So 746 01:02:11,967 --> 01:02:15,807 Let's add here some variable 747 01:02:30,911 --> 01:02:32,959 Okay 748 01:02:47,295 --> 01:02:53,183 You went online and offline partner 749 01:02:53,951 --> 01:02:56,511 is Persistent after that 750 01:02:56,767 --> 01:02:59,839 The old breakpoints is activated to use 751 01:03:00,351 --> 01:03:03,935 So let's see here there is a break point 752 01:03:04,447 --> 01:03:10,591 Let's monitor available is 150 753 01:03:14,175 --> 01:03:19,807 But be careful assigned my program in background so 754 01:03:20,319 --> 01:03:22,623 if i Activate 755 01:03:22,879 --> 01:03:24,159 The breakpoints 756 01:03:26,463 --> 01:03:32,607 Note that brakepoints could be activated do you want to take the 757 01:03:32,863 --> 01:03:36,703 The first thing to develop test now and I say yes 758 01:03:51,551 --> 01:03:53,599 call positions 759 01:03:53,855 --> 01:03:55,903 okay 760 01:03:57,439 --> 01:04:02,559 CPU is in run and 761 01:04:03,839 --> 01:04:08,703 Debug mode background task to be stopped at this case 762 01:04:15,359 --> 01:04:17,919 Let's check the operating States 763 01:04:30,719 --> 01:04:33,791 You'll see a background task is running 764 01:04:43,007 --> 01:04:48,127 set in simotion 765 01:04:49,151 --> 01:04:52,479 in back program I hit to activate 766 01:04:59,647 --> 01:05:01,183 Okay 767 01:05:02,207 --> 01:05:07,071 Now it's broken and background task is 768 01:05:07,583 --> 01:05:10,143 Stop right here as you can see 769 01:05:12,191 --> 01:05:18,335 It's not logical to do this operation in background task but it's 770 01:05:18,591 --> 01:05:24,735 On the other hand looks like this now or program interpreter located 771 01:05:24,991 --> 01:05:27,295 line 49 772 01:05:28,063 --> 01:05:30,623 At this point at this breakpoint 773 01:05:30,879 --> 01:05:36,767 Then I can continue the same way as the MCC charts just continue 774 01:05:46,751 --> 01:05:50,847 at next cycle same breakpoint the program Brooks again 775 01:05:51,103 --> 01:05:53,407 I have to deactivate the breakpoints 776 01:05:53,663 --> 01:05:57,247 After that I hit the continiue 777 01:05:58,015 --> 01:06:00,063 And program continues 778 01:06:01,087 --> 01:06:05,183 So I can see it is running so 779 01:06:05,695 --> 01:06:10,815 Homework for you create structure program 780 01:06:11,327 --> 01:06:16,191 structure text and test your program in simulation 781 01:06:16,447 --> 01:06:17,727 See you next time
