Hello. 1
In this video we are going to learn serial communication pin definitions. 2
Why these definitions are important when you communicating with the plc or hmı or external device. 3
We are going to use rs232. 4
rs422-485 5
Communication with the serial communication. 6
So we need to know how to create our cable with the true connection. 7
So for com1 you need to know Rxd R means receiver receiving t means transmitting 8
five is ground, so ground connection and 7-8 RTC and CTC. 9
So in here you can see a complete definitions of the mode 1 and mode 2 and Mode 3 according to 9 pins 10
female connector in here for download and upload cable for RS 232. 11
If you want to go online to your plc and upload or your download your plc projects. 12
So you need to adapt your cable like this. 13
So in the one side Rxd should connect to two and the other side. 14
Txd 15
So it's cross cabling and Txd. 16
Pin number is three. 17
But the other side it needs to connect to Rxd 18
And second connection or second pin. 19
We can say it like this and ground needs to connect to ground and you can see in here cross section is 20
for the CTC and RTS also. 21
But when you connect your cable like this or create your cables 2 and 3 ,3 and 2 and 5 and 5. 22
If you create your cable like it is just 2 3 and 5 these pins are used. 23
So that cable is going to work also. 24
And for Dop-b and the plc cable so dop-b means hmı and plc communication for RS485 25
--. 26
So dop 9 pin male side. 27
So hmı side. 28
The connection of first pin needs to connect to +, + for are RS485 communication 29
and the for the hmı side. 30
Sixth pin needs to connect to - , and dop plc cable for the RS232 31
communication. 32
HMI side or second pin needs to go. 33
Fifth pin of eight pin of male connector, you see like this and third pin of the HMI needs to go. 34
Fourth pin of plc side and the fifth pin of dop hmı side needs to go eight pin of this cable 35
This is hmı side nine pin male connector. 36
And this is for the plc side and dop-as and Plc cable for that RS485 37
communication. 38
This is also another hmı type of Delta plcs. 39
If you look to scheme , so you can see are X minus and takes minus or receiving and transmitting minuses 40
are connect to two minus cable are x plus and takes plus is connected to plus pin or plus cable and 41
this is r converter from RSA for under into five to use B converter I have the six thousand five hundred. 42
This is a device so if you want to connect your I fifty six hundred and six thousand five hundred device 43
to your P.C. and if you want to convert your address from that I need five communication to use B so 44
you need to adapt your cable like this from top to lower side so that means from 1 it's starting from 45
1 to 8 pain for must connect to minus four IRS for underline eight five communication we need one minus 46
one plus cable C G minus needs to connect to fourteen C G plus needs to connect to fifteen so also if 47
we want to connect or convert your cable from r r g eleven to R S for under eighty five you need to 48
adopt your r g allow on cable like this green cable needs to connect your fourth pin so green is minus 49
S G minus the green cable or it can be the color can be anything else so maybe you are adapting your 50
cables and you have another color so you should notice one cable or minus cable needs to connect to 51
four then + cable needs to connect to three for RS485 communication. 52
So for this video I am finished. 53
See you in the next video.
