Digital Module Parameter Assignment

Introduction

Digital modules can have different characteristics. You can set the characteristics

of dome modules by means of parameter assignment.

Tools for Parameter Assignment

You assign parameters to digital modules in 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 digital modules.

Static and dynamic parameters

The parameters are divided into static and dynamic parameters.

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

In addition, you can modify the dynamic parameters in the current user program in

an S7 programmable controller 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.
