Hello
I am trying to learn IEC 1131-3 and I am completely new to PLC programming. I have some trouble understanding how to write function and block function.
Can somebody show me a code example of how to program the following in Structured Text
1) Define a function.
2) Define a block function.
3) Call a function.
4) Create an instance of a block function.
5) Call a block function.
