4.23.1 Commissioning the SM 331; AI 8 x RTD
You set the mode of operation of the SM 331; AI 8 x RTD in STEP 7.
Parameter
You will find a description of the general procedure for assigning parameters to
analog modules in Section 4.7.
Parameterization restrictions when using the SM 331; AI 8 x RTD with
PROFIBUS masters that only support DPV0.
When you use the analog input module SM 331; AI 8 x RTD in an ET 200M
PROFIBUS slave system with a PROFIBUS master which is not an S7 master,
certain parameters are not permitted. Masters that are not S7 masters do not
support hardware interrupts. So all the parameters associated with these functions
are deactivated. The deactivated parameters are hardware interrupt enable,
hardware restrictions and end-of-scan-cycle interrupt enable. All the other
parameters are permitted.
An overview of the parameters that you can set and their default settings are
shown in the table below.
