CI840 4.2.2 Version DO Flickering Issue( redundant slave does not exist)
We are using xa 5.0 sp2 RevD Software version.
In one of the CI840 Cluster we observed message " redundant slave does not exist"
Changed CI840 modules- Problem persists.
So, again changed baseplate also of CI840 cluster - still problem persists.
This is last cluster of 800M node.
Checked Profibus connectors healthiness. (terminations and wiring).
Profibus connectors used are of Phoenix make.
Now random Digital Output channel of that particular CI840 cluster are flickering.
DO Flickering is not frequent.
Ci840 version - 4.2.2.
Anybody have faced issues with 4.2.2 ?
Is this an issue of firmware or BUS ?
