Ladder logic sample programs


Thread Starter

Marko Matic

Hi everyone! I have some knowledge in PLC programming but I am lacking the practical experience. Is there anyone who will help me with Analog I/O and PID programming samples in ladder logic (AB SLC500 or STEP7 PLC). I need simple examples which will help me with understanding. Thank you in advance Marko Matic

In SLC 500 is easy with Rslogix 500 Software, there is a function called PID with diferent parameters to configure. If you have RSLogix, I can send examples to learn about instruction.

In Step 7/Micro-Win, there is a wizard for PID instruction. It creates the code for you. You can download sample programs for S7-200 from Hakan Ozevin
