With the GW PL DIO4-BUS, the status of digital input signals can be monitored. A value of
1
indicates the input is on, and a value of
0
indicates the input is off (see
).
With the GW PL DIO4-BUS, the digital output signals can control external devices by writing
a
1
to turn on the output channel and writing a
0
to turn off the output channel (see
