9.2 Network Status Screen
The Network Status screen provides a visual reference of the overall health of the MOV field network. See section 5 for
instructions for viewing the MOV and communication channel status. MOV faults can be examined by clicking on the
desired unit. Communication channel faults can be examined by reviewing log files. Communication channel faults can
be corrected by verifying correct configuration parameters (see section 7) and verifying wiring connections and proper
cabling.
