Thanks in advance!
Which firmware version does your PM866 have?
You can also check:
-Time sync status
Were there recent downloads to the controller?
-Code loops (for/while loops)
-Alarm or event bursts
If the plant/process allows some possible disturbance, try some exclusion of possible causes.
1. If you have a redundant network, you can try to unplug the primary network.
2. If you have a redundant controller, switch over to the backup controller.
3. Unplug the profibus for a short while if possible.
4. Try a controller reset and fresh download, if possible.
DISCLAIMER: Please use caution when trying the tests (1-4) above. Process can/will be disturbed and values/parameters can be lost depending on the programming (retain/cold retain).
