A.3 Parameters of digital output modules
Parameters
The table below contains all parameters you can set for digital output modules. The
comparison shows:
● Which parameters you can change with STEP 7 and
● Which parameters you can change using SFC 55 "WR_PARM".
The parameters set with STEP 7 can also be transferred with SFCs 56 and 57 to the module
(refer to the STEP 7 manuals).
Table A- 5 Parameters of the digital output modules
Parameters Data record
no.
Parameter assignment
with SFC 55
Parameter assignment
with STEP 7
Destination CPU for interrupt No Yes
Diagnostics
0
No Yes
Diagnostics interrupt enable Yes Yes
Reaction to CPU STOP Yes Yes
Enable substitute value "1"*
1
Yes Yes
Note
If you want to enable the diagnostic interrupt in the user program in data record 1, you must
enable the diagnostics in data record 0 beforehand using STEP 7.
Structure of data record 1
The figure below shows the structure of data record 1 (bytes 0, 1 and 2) for the parameters
of digital output modules.
You enable a parameter by setting a logical "1" at the corresponding bit.
