Communication BRC410 to IMMFP01
I faced some problem from last 6 mix months that after 6-7 days some time after month all communication signals loss which are communicating from BRC410 to IMMFP01. and after some seconds all normal. And on event list i got the error.. Details are attached. Only error moderror on IMMFP01(MFP LOW 1).
Regarding the NMODERR
Snipped from the 800xA for Harmony Operation manual
• Noffline - Indicates that the node has been taken offline
• Nmoderr - One or more module errors.
• NcommErr - Module communication errors.
• NsysErr - One or more node system errors.
So in summary
NMODERR is hardware faults, Local and Remote IO problems and signal quality issue.
NCOMERR is to do with system communications. I.e. Cnet, Controlway, Module bus.
NSYSERR is Power, Fans, Temperature or Node Environment Status, as it's now called.
Have a look at using the MODST (FC95) to monitor the status bytes of the controller and maybe the associated NPM. The TSTQ (FC31) may also be useful in determining where the signals are being lost.
