1.6 Compatibility with the previous product
What to do / module replacement
Supply the new module with an adapted configuration as
follows:
1. In STEP 7 / HW Config, replace the already configured CP 342-
5 with the new module; You will find this in the hardware
catalog.
2. Save, compile and load the configuration data to the CPU or
CP again.
Case a: Configuration unchanged
If you have no requirements beyond what you had with the
previous CP (for example configuration limits), you do not need
to make changes in the configuration.
You only need to remember the following distinction during
commissioning:
•
With the module you are replacing, you chose to have the
configuration data stored on the CPU.
When you start up the CP, the configuration data will be
loaded automatically from the CPU.
•
You had not chosen this option for the CP you are replacing.
In this case, load the configuration data again from your
PG/PC to the CP.
Case b: adapted configuration
If you want to use the extended options of the new CP, follow
the steps below:
1. Use the new FCs (version 3.0 or higher; see also section
Compatibility in the user program in DP mode (Page 24)) in
your user program.
Note: If applicable, remember changes to the data format of
the ANY pointer on the FC interface; you will find more
detailed information in the online help for the blocks.
2. In STEP 7 / HW Config, replace the already configured CP 342-
5 with the new module; You will find this in the hardware
catalog.
3. Expand your configuration to suit your needs, for example
the connection configuration.
4. Save, compile and load the configuration data to the CPU or
CP again.
