5.5 Managing the Parameter Data
Introduction
The configuration and configuration data of the CP 440 is saved in the current project (on the
hard disk of the programming device/PC).
Data management
When you exit the configuration table by selecting the Station > Save or Station > Save As
menu command, the configuration and configuration data (including the module parameters)
is automatically saved in the project/user file you have created.
Loading the configuration and parameters
You can download the configuration and configuration data to the CPU from the
programming device (by selecting PLC > Download). The CPU accepts the parameters
immediately after the download.
The module parameters are automatically transferred to the CP 440 in the following cases:
● When they are downloaded to the CPU and the CP 440 can be reached via the S7-400
backplane bus
● After power up during startup of the CPU, as soon as the CP 440 can be reached via the
S7-400 backplane bus
Default settings apply if parameters are not changed.
Further Information
You can find out how to do the following in the Configuring Hardware and Communication
Connections STEP 7 manual:
● save the configuration and the parameters,
● load the configuration and the parameters into the CPU,
● read, modify, copy and print the configuration and the parameters.
