Failsafe mode [ on/off ]
Default: off
Failsafe mode = off:
The IO-Channel is deactivated if no connection to the Ethernet/
IP scanner is established .
Failsafe mode = on:
The IO-Channels remain activated and the outputs keep the
last received state if no connection to the Ethernet/IP scanner
is established .
