1) The configuration data is stored on the CPU or on the CP. This option can be

selected in the properties dialog of the CP (in “Replace Module without PG” in

the “Options” tab).

Note

Recommendation for data storage

If you use the CP in a complex plant configuration, for example as PROFINET IO

controller with up to 128 IO devices, the configuration data will be correspondingly

extensive. In such cases, the time for the transfer of the configuration data from

the CPU to the CP may take several minutes.

In such case, you should weigh up the pros and cons of storing the data on the

CP.
