@Marcjan:
I think what enrique.juarez wants to tell us, is that he is designing a control system that controls x20 motors. He would like to know what is better to use. ------------------------------------------------------------- @enrique.juarez: Welcome. It will help my friends here if you explain which PLC you are going to use for the task. In my opinion the FB is the better choice.. you create one code block and re-use this block. BUT each use of the FB has its own DB. In your case x1 FB but x20 DB. The problem however comes in when you want to monitor the block online to the PLC. The S7-1200 before firmware 4.0 is difficult to do this. But even on other PLCs there are a trick to it. I will leave you with this in the hope that others will fill in the gaps. Greetings. w |
