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).
