Parameters of analog input modules
Parameters
The table below lists all parameters you can set for analog input modules.
The comparison illustrates the parameters you can edit:
● In STEP 7
● 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).

Note
If you want to enable the diagnostic interrupt in the user program in data record 1, you must
enable the diagnostics in data record 0 beforehand using STEP 7.
Structure of data record 1
The figure below shows the structure of data record 1 for the parameters of analog input
modules.
You enable a parameter by setting a logical "1" at the corresponding bit.
