Post by lamine97 on Issue with Timer-Based Increment Function in CoDeSys Ladder Logic (LD) ^{CODESYS Forge talk (Post)}
I am trying to implement a Ladder Logic (LD) function block in CoDeSys that increments a value A by B every T time interval. My Structured Text (ST) version works perfectly in simulation, but when I implement it in LD, it does not work. The ST code: PROGRAM ADDITION VAR_INPUT A : LREAL ; B : LREAL ; T : TIME ; END_VAR VAR Timer : TON ; END_VAR Timer (IN:=TRUE, PT := T); IF Timer.Q THEN A := A + B ; Timer(IN := FALSE ) ; END_IF;

Post by george32 on Learning ST in an object-oriented way. ^{CODESYS Forge talk (Post)}
Dear all, I am currently creating a program in the ST language. Because the program is starting to grow nicely I would like to switch to a more object-oriented way of programming. (Like for example in Python). By surfing the internet I found out that Function Blocks is the best method for this. Now I would like to delve further into this, with all the possibilities that Function Blocks have only I cannot find a clear course, explanation of what everything is around the function block thing and how to approach everything. I find the standard documentation around Function Blocks rather abstract and the examples are minimal. Therefore I am looking for a page/course/document explaining object oriented programming in Codesys (or other PLC programming environment). Do you have any recommendations on this?

Post by sturmghost on Visualization using methods and cyclic ST-calls ^{CODESYS Forge talk (Post)}
I found a way to do it: You can use, for example, the text variable property of any visualization element and call a function in it. Example: Write a test POU as a function (FUN), like MyTestFun which need a boolean Variable as an input value. Now write into the text variable property: MyTestFun(bBooleanValue) Thats it. The function is called at each visu_task cycle.

Have you found the way how to call any function in case the visu is opened? Like on event when the screen is opened to initialize some variables etc.? I can´t... :/
