A.6 Parameters of the SM 331; AI 8 x TC
Parameters
The table below contains all the parameters which you can set for analog input
module SM 331; AI 8 x TC.
You will see which parameters you can modify from the list:
• In STEP 7
• With 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).
