Steps in Configuration
Supply the new module with the adapted configuration as described
below:
1. In STEP 7 / HW Config, replace the previously configured CP
342-5 with the new module (you will find this in the hardware
catalog).
2. Save, compile and download the configuration data to the CPU or
CP again.
Case a: Unchanged configuration
If you do not require any extension of the functionality provided by
the previous CP (such as amounts of data), you do not need to make
any changes in the configuration.
When commissioning, you then only need to remember the following
difference:
S
If you selected the option of storing the configuration data of the
CP you are replacing on the CPU, the configuration data will be
downloaded to the CP from the CPU automatically when the CP
starts up.
S
Otherwise, download the configuration data again to the CP from
your programming device/PC.
Case b: Adapted configuration
If you want to use the extended functionality of the new CP, follow the
steps outlined below:
1. Use the new FCs (version 3.0 or higher; see also page 21) in
your user program.
2. In STEP 7 / HW Config, replace the previously configured CP
342-5 with the new module (you will find this in the hardware
catalog).
3. Extend the configuration according to your requirements, for
example in the configured connections.
4. Save, compile and download the configuration data to the CPU
and CP again.
