1.6.3 Confirming the communication state to each station (station monitoring
function)

register (GS).
(1) No. of faulty stations
(a) For the Ethernet connection (except for the Ethernet multiple connection)
The total No. of the faulty CPUs is stored.
(b) For the Ethernet multiple connection
The total No. of the faulty devices is stored.
