Assigning parameters to the SM 422; DO 16 x DC 20-125 V/1.5 A

Parameter assignment
You will find a description of the general procedure for assigning parameters to digital modules
in the respective sections.
Parameters of the SM 421; DO 16 x DC 20-125 V/1.5 A
You will find an overview of the parameters you can set and their default settings for the SM
422; DO 16 x DC 20-125 V/1.5 A in the following table.
Table 4-12 Parameters of the SM 421; DO 16 x DC 20-125 V/1.5 A
Parameters
Enable
● Diagnostic interrupt
1
● Destination CPU for interrupt
Reaction to CPU STOP
Diagnostics
● Load voltage L+ missing
● Short-circuit to M
Set substitution value "1"
If you use the module in ER-1/ER-2, you must set this parameter to "No" because the interrupt lines are not available in
1
ER-1/ER-2.
Only in the CR (central rack) is it possible to start up the digital modules with the default settings.
2
Assigning the "No load voltage L+" diagnostics to channel groups
You can only set the "No load voltage L+" diagnostics separately for each channel group. In
other words, the setting for channel 0 applies to inputs 0 to 7, and the setting for channel 8
applies to inputs 8 to 15.
