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?
