Hi
I wonder what methodology you expierenced Siemens users have to troubleshoot complex programs.
* Reproduceable fault, slow process: this is easy, using VAT tables
* Reproduceable fault, fast process: this makes me wonder already. In my previous job, I used a scope monitor in my Beckhoff PLC's to monitor which state variable or which boolean went wrong for some 10 ms, or to monitor that state_variable_1 went to '5' one cycle too early, compared to state_variable_2.
* Non reproduceable fault, once a week: I don't have a clue here.
