ControlNet Error

[aprilchu]

Dear All,

I have a porblem related with ControlNet Error. I used a redundancy
connection in 1756-CNBR/E, that is Channel A and Channel B. When one of
the Channel is disconnected, there is a flashing red LED in that
Channel in the module. But there is no system fault indicated in the
RSLogix 5000. Can you suggest how can I get this information in RSLogix
5000?

If both of channels are disconnected, this information can shown in
RSLogix 5000. (Properties>Module Fault)

I also found that if there is only one channel is disconnected, RSLinx
Classic Shows flashing RED in that LED in ControlNet Module. Is there
any method to get this information to RSLogix 5000?


Thanks

I haven't tried this myself, but here is a Rockwell Tech Note describing a MSG instruction to do what you are asking.
