Managing the Parameter Data

Introduction
The configuration and parameterization data of the communication processor is stored in the
current project (on the hard disk of the programming device/PC).
Data management
When you quit the configuration table by selecting the menu command Station > Save or
Station > Save As, the system automatically saves the configuration and parameterization
data (including the module parameters) to the project/user file you have created.
Downloading the configuration and parameters
You can now download the configuration and parameterization data online from the
programming device to the CPU (menu command PLC > Download). The CPU accepts the
parameters immediately after the download.
The module parameters are automatically transmitted to the communication processor
● When they are downloaded onto the CPU and as soon as the communication processor
● When the CPU's operating mode changes from STOP to RUN (CPU startup).
Unchanged parameters have the default value.
Further information
The STEP 7 manual
describes in detail how to
● Save the configuration and the parameters
● Download the configuration and the parameters to the CPU
● Read, modify, copy, and print the configuration and the parameters.
● You will find more information on the parameters in the chapter titled "Parameterization
