11.10.4 Response of digital outputs to faults or SIMATIC STOP
This parameter allows you to define the response of the digital outputs following a fault of the
SIWAREX module or SIMATIC STOP.
Value
Response
0
Outputs are switched off
1
Outputs are not switched off (continue)
2
The relevant substitute value is activated
3
Outputs are switched on
11.10.5 Substitute value for DQ 0, 1, 2, 3 following fault or SIMATIC STOP
The outputs are usually reset following a module fault (operating error) or SIMATIC CPU
STOP. This response is the default setting.
If an output is to be set following a fault, this response is defined using this parameter. The
"Response of digital outputs to fault or SIMATIC STOP" parameter must also be set to
"Output substitute value".
The substitute value definition is then valid.
