Failsafe function
The firmware of the modules provides a fail-safe function for the outputs.
During the configuration of the modules, you have the option to define the
status of the outputs after an interruption or a loss of communication.
The following options are available:
Set low
: Deactivates the output channel (value = 0)
Set high
: Activates the output channel (value = 1)
Hold last
: Holds the last output status (value = 2)
