AF100 Fieldbus Module warning on system 800xA 6.0.1
I have raised a Support Case #20190925-1537780 to Local Support Line (Singapore) but take too long to receive the information/solution for that. So I post it here to get your support or other experts can help.
I brief Support case as below
In my system 800xA ver 6.0.1, I have received these messages from System message (attached screenshot),
I used ONB to check AF100 item:
- WARN = 1
- ERR = 0
- DIAG = SE (both modules)
There is no any system message from ONB for this node.
The operation is still working.
*** No any modification on the hardware/software of CI522.
Thank you for your support.
When redundant CI522s and CI820s are used on the bus, then one of the following rules must be followed:
– The redundant CI522 pair must be assigned a station number lower than five (5). – Two master defined communication interfaces must be assigned station numbers lower than five (5).
One side effect when using station number 5 or higher is a not properly working system status for the CI522 boards.
It is very easy to change the CI522 board station number from 79 to 1 but, then if station 1 exists on the bus, you must
change that station number and all I/O boards to a higher not used station number.
Econfig mode is required.
