Steps for commissioning analog modules
Introduction
The following table contains the tasks that you have to perform one after the other to
commission analog modules successfully.
The sequence of steps is a suggestion, but you can perform individual steps either earlier or
later (for example, assign parameters to the module) or install, commission etc. other modules
in between times.

Steps from the selection of analog modules to commissioning
Step
Procedure
1
Select the module.
2
For certain analog input modules: Set the measuring type and range using the measuring
range module.
3
Mount the module in the rack.
4
Assign parameters to module.
5
Connect the measuring sensors or loads to the module.
6
Commission the configuration.
7
Analyze the configuration if commissioning failed.

General information
Introduction
This chapter describes the analog values for all measuring or output ranges supported by the
analog modules.
Analog to digital conversion
Analog input modules convert the analog process signal into digital form.
Analog output modules convert digital output values to analog signals.
