4.22.1 Commissioning the SM 331; AI 8 x 12 bits
You set the mode of operation of the SM 331; AI 8 x 12 bits by means of
measuring range modules on the module and in STEP 7.
Meas. range module
If necessary, the measuring range modules must be replugged to change the
measuring method and the measuring range. The steps you have to perform to do
this are described in detail in Section 4.4.
The corresponding table in Section 4.22.2 tells you which assignment you have to
select for which measuring method and measuring range. In addition, the
necessary settings are embossed on the module.
