We have a machine with Siemens PLC and Siemens HMI but the drives are not Siemens. When we are running the lubrication sequence it stops before the end is reached and there are 2 alarms in the alarm list. Overspeed and overcurrent on the lubrication drive. I am not certain that it is these alarms that are stopping the sequence but I would like to know for sure by tracing the signals in the logic and see where and when the alarms are generated. How do I track backwards in WinCC where the overspeed and overcurrent alarms are generated? Attachment WCC A.zip (150 Downloads)

I can see that I did not make screenshots of those places (and I did make many screenshots). I have now made screenshots of only those areas. Am I looking in the wrong place or how do I find the telegrams mentioning the speed and/or current? bg2492 Hello xmnj, the messages are not be seen in your screnshots.

I THINK I looked everywhere - but I am not sure what you mean by "top of theAlarm loggingtree" Can you explain a little more - perhaps even with a screenshot?
