Hello. 1
In this video we are going to learn ST operators this is really important. 2
While we are writing ST or structure text programming in the Delta plc you can see precedence 3
is highest one. 4
It is a parenthesis the parenthetical part of an expression is calculated first. 5
This is important. 6
It is coming from the Math and you can see the expression example in here. 7
So what will happen. 8
Six multiplied by three. 9
No this is not going to happen first. 10
D0 +6 will be edit and then it is multiplying by 3. 11
For example Exponentian 12
This is the second highest precedence so for this what will we do with exponentiation 13
2.0 exponent 5.0. 14
So it will be equal to 32. 15
So it is also . 16
This is similar to you maybe 3.2E+1 equals 3.2x10 17
3.2 x10 = 32 18
This is ten. 19
This is 3.2 20
It equals to 32 21
And also this is not logical. 22
The logical negation. 23
So it is similar with the inverted contact in the Delta plc and also plus and minus. 24
Addition and subtraction you can see it expressions in here for example AND contact. 25
This is our contact normally open and this is and contact or contact that we used in the Delta plcs 26
is like this for example and OR contact is in the ST language will be OR logical inclusion OR 27
operations M0 or M1 we will use it like this M0 or M1..and comparisons or the AND operations or 28
equal or negative signs or reminders divisions and are etc. complete as the operators examples expressions 29
examples and the function and symbols is in this page. 30
You can just copy or take a photo of this page while we are writing ST language programming or we are 31
doing and examples about the ST programming done we will need these operators for ST programming 32
then I I'm going to finish this video. 33
wE need to know these are all while we are working with a st programming so that's all. 34
See you in the next video.
