5.4 Management of the Parameter Data
The configuration and parameterization data of the CP 440 is saved in the current
project (on the hard disk of the programming device/PC).
Data Storage
When you exit the configuration table (see Section 5.1) by choosing the Station >
Save or Station > Save As menu command, the configuration and
parameterization data (including the module parameters) is automatically saved in
the project/user file you have created.
Downloading the Configuration and Parameters to the CPU.
You can download the configuration and parameterization data to the CPU from
the programming device (by choosing PLC > Download). The CPU puts the
parameters into effect as soon as they are loaded.
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
Unchanged parameters have the default value (see Section 5.3).
