CI854A Primary to Redundancy Switching Problem.
I am having CI854A in Redundancy Mode.Whenever i am switching from Primary to Redundant CI854A switching is not Bumpless.
Means Redundant CI854A Module going in Error Mode for 5-10 Seconds and then Become Normal.
So Communication is lost during this 5-10 Seconds.
In order to ensure proper redundacy you should pre-check below points:
1.Should have common firmware in both ci854.
2.redundancy to be configured in CBM as right click the module & add redudant unit position generally for segment with BC810 used then 1(7),2(8) means 1 belongs to upper segement(1 to 6)ci854 & 7 means ci854 in lower segment (7 to12).
3.profibus cables should be connected with each other such that removal of any ci854 doesn't affect the line redundancy.
