A.2 Parameters of digital IO modules
Parameter
The table below lists the parameters you can set for digital input modules.
Note
For details on parameters of programmable digital IO modules, see the chapter dealing with
the relevant module.
The comparison illustrates the parameters you can edit:
● in
STEP 7
● using SFC55 "WR_PARM"
● using SFB53 "WRREC" (for GSD, for example).
Parameters set in
STEP 7 may also be transferred to the module using SFCs 56 and 57, and
SFB53 (refer to the
STEP 7 ) Online Help).
