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 jarnok on How to know if output if function block is used ^{CODESYS Forge talk (Post)}
Hi, Is it possible to know of an output of a function block is used? I've found there is a way to find unused inputs of a fb, through the attribute: is_connected. But I'm wondering if the same can be done for an output. Thanks in advance!
