Hello engineeer; I have never come upon such a problem with a Siemens PLC, where a profibus fault is b=not reflected on the PLC's diagnostic LEDs, or logged in the diagnostic buffer with a known error code. Looking at the entries in your diagnostic buffer, the error ID E0CD appears on most or all of the entries. There is a list of Siemens diagnostic buffer error codes, but this E0CD error code does not appear in it: https://support.industry.siemens.com/cs/ca/en/view/770453 I cannot find a similar document for Vipa PLCs, but a web search for "E0CD" in Vipa CPUs does not return any hit. At this point I can only suggest you question Vipa support directly and inquire what they think of your Profibus problem. Hope this helps, Daniel Chartier |
