A-2 Manual, 08/2006, A5E00105505-04
Description of the parameters
The next chapters describe all modifiable parameters of the various module classes. For
information on signal module parameters, refer to:
● the
STEP 7
Online Help
● to this Reference Manual
The chapters dealing with the various signal modules also show you the corresponding
configurable parameters.
Further references
For detailed information on programming signal modules in the user program and on
corresponding SFCs, refer to the
STEP 7
manuals.
A.2 A.2 Parameters of digital input modules
Parameters
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 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).
