Extract thread info with CBM->Remote System->Controller Diagnosis -or- AC800MFingerPrint.exe tool.
Compare with healthy controller.
Module bus problem?
Hello,
There are many reasons causing system load 100%
Check for the network loops if any(use rnrp fault tracer).
Check for the controller diagnostics with no of alarms flooding compare with good one.
Check for the network settings.
Check for the system alarms/events for clue.
Which firmware version does your PM866 have?
You can also check:
-Controller logfile
-Task analysis
-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).

System Total Load becomes normal after restarting the Primary CS
