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. 
 
Outputs are not switched off (continue) 
The relevant substitute value is activated 
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. 
Examples 
Table 11- 9  Bit 0 defines digital output 0 (DQ.0) 
Value of DQ.0 following fault 
 
Table 11- 10  Bit 1 defines digital output 1 (DQ.1) 
Value of DQ.1 following fault
