Hallo Guys, I am completely new to PLC ladder programming. I have a question regarding the Main OB1 cyclic execution. I am using TIA portal v15 and PLC 1511T_PN . My understanding is Main OB execution should be sequential that means Network2 will be executed after network1 is completed and so on. But, my code in mainOB is always toggling and seems not stable sequential execution. It seems command executed for some time and after some same command executed further. Is there anything I am missing. Any lead will be helpful. ------------------------------------------------------------------------------------------ |

I'm not entirely sure what you mean. Maybe you can give us some screen shots and a detailed explanation? |
