1)
Ifthe interface module is withoutpower, the digital output module does not output substitute values. Output
value = 0.
2)
Wire break is only detected when the output is switched off.
Process alarm
This parameter enables the process interrupts for the module.
Input delay
Signal interference can be suppressed with this parameter . Changes in the signal
are only detected after the specified time.
Trigger for process interrupt, rising edge
This parameter can be used in channels to enable a process interrupt with a rising
edge (a signal status change).
