A.2 Parameters of the Digital Input Modules
Parameters
The table below contains all the parameters you can set for digital input modules.
Note
For details of the parameters of parameterized digital input/output modules, see
the respective chapter of the module concerned.
You will see which parameters you can modify from the list:
• In STEP 7
• With SFC 55 “WR_PARM”
• With SFB 53 “WRREC” (e. g. for GSD).
The parameters set with STEP 7 can also be transferred with SFCs 56 and 57 and
the SFB 53 to the module (refer to the STEP 7 manuals).
