Commissioning the SM 431; AI 16 x 16 Bit

Setting the operating mode
You set the mode of operation of the SM 431; AI 16 x 16 Bit by means of measuring range
modules on the module and in STEP 7.
Measuring range modules
A measuring range module of the module matches two channels and one resistance channel
to each type of sensor. Reposition the measuring range modules to suit the measuring method
and range. The steps you have to perform to do this are described in detail in the respective
section.
For an overview of the settings of specific measuring methods and ranges, refer to the
corresponding table in the section "Measuring methods and measuring ranges of SM 431;
AI 16 x 16 Bit". The necessary settings are also shown on the label attached to the module.
Parameters
You will find a description of the general procedure for assigning parameters to analog modules
in the respective sections.
The table below provides an overview of configurable parameters, including defaults.
