The status of the MS and WS indicators depends on the communications sta-
tus, as follows:
The MS (Module Status) indicator shows the status of the local node.
The WS (Wireless Status) indicator shows the status of the wireless system.
During normal operation these two indicators are lit green on both the Serial
Master Station and the I/O Slave Stations.
