Analog modules can have different characteristics. You can set the characteristics
of the modules by means of parameter assignment.

You assign parameters to analog modules with STEP 7. You must perform
parameter assignment in STOP mode of the CPU.

When you have set all the parameters, download the parameters from the
programming device to the CPU. When there is a transition from STOP to RUN
mode, the CPU transfers the parameters to the individual analog modules.

In addition, if necessary you must place the measuring range modules of the
module in the necessary position (refer to Section 5.4).

The parameters are divided into static and dynamic parameters.

Set the static parameters in STOP mode of the CPU, as described above.

You can similarly modify the dynamic parameters in the current user program by
means of SFCs. Note, however, that after a change from RUN 

³

 STOP, STOP 

³

RUN of the CPU, the parameters set in STEP 7 apply again. You will find a
description of the parameter assignment of modules in the user program in
Appendix A.
