Steps in selecting and commissioning the digital module
Introduction
The following table contains the tasks that you have to perform one after the other to
commission digital 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.

Assigning parameters to digital modules
4.3.1
Parameters
Introduction
Digital modules may have different features. You can configure the features of some modules.
Tools for parameter assignment
You assign parameters to digital modules in
STEP 7.
After you have defined all parameters, download these from your programming device to the
CPU. On a transition from STOP
>
RUN mode, the CPU then transfers the parameters to the
individual digital modules.
Static and dynamic parameters
The parameters are divided into static and dynamic parameters.
