Parameters 
The table below contains all parameters you can set for digital output modules.  
 
 
Note 
For details on the parameters of programmable digital IO modules, see the chapter dealing 
with the relevant module. 
 
The comparison illustrates the editable parameters: 
●  in 
STEP 7
 
●  using SFC 55 "WR_PARM" 
●  using SFB 53 "WRREC" (for GSD, for example). 
Parameters set in 
STEP 7
 may also be transferred to the module using SFCs 56 and 57, and 
SFB 53 (refer to the 
STEP 7
) Online Help).
