Hello,
I have an old S7 200 with a 214 CPU. The program it is running is written in LAD form. Only Digital I/O is used, and now expansion modules are attached. I want to simulate this program, and thought of using Siemens' PLCSIM or WINPLC.
All I am looking for, is to find any problems in the program if an unexpected Input is encountered: So I want to monitor I/O and memory locations when simulating different Inputs.
I do not care about the scan time (it is a slow process anyway).
I do not think I need a 214 compatible Emulator to do the simulation work, or what? I mean, the CPU 214 program is written in Ladder form and I guess I can recreate the same Ladder logic on a S7 300.
Comments are highly appreciated !
