Understanding the COMM
Status Indicator

The COMM status indicator provides status information on the DeviceNet
option.

Important: When power is first applied to the DeviceNet option, the

COMM status indicator flashes green for 1/4 second, red for
1/4 second, and then goes blank while the communication
module finishes its initialization.
