A.8 Parameters of the SM 331; AI 8 x 16 bits
Parameters
Table A-23contains all the parameters which you can set for the isolated analog
input module SM 331; AI 8 x bits. This comparison indicates which methods you
can use for the configuration of the individual parameters:
• SFC 55 “WR_PARM”
• STEP 7 programming device
The parameters that you have set with STEP 7 can also be transferred to the
module by means of SFC 56 or SFC 57.
