Communication Error
The following are common causes for communication error ( C ) to be
displayed on the 7-segment LED:
• The MBCN couldn’t open one or more connections. Look at the
status for each connection in RSNetWorx or on the MBCN
• The MBCN has refused a connection or has returned an error to an
unscheduled message. Look at the status for each connection using
RSNetWorx or the status registers on the MBCN or look at the status
of the connections on other nodes that have connections to the
MBCN.
• The MBCN is sending unscheduled messages that are failing.
