**) ***)

Case a: Configuration unchanged / module replacement

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:

 If the option of storing the configuration data of the CP

on the CPU was selected for the CPU you are replacing,

when the CP starts up the configuration data is loaded

automatically from the CPU to the CP.

 Otherwise, download the configuration data again from

your PG/PC to the CP.

Case b: Adapted configuration / upgrade

If you want to use the extended options of the new CP,

follow the steps below:

1. Replace the previously configured CP with the new

module in STEP 7 / HW Config. You will find this in the

hardware catalog.

2. Expand your configuration to suit your needs, for

example the connection configuration.

3. Save, compile and load the configuration data to the

CPU or CP again.

Note

Note the following information on the module types listed in the table above:

**) With the current CP, note the changed number of possible connections and the smaller

PROFINET IO configuration limits as well as the omission of support for PROFINET CBA**).

**) If you replace a module, you will need to download the adapted configuration data to the

new module type using STEP 7. The procedure is therefore only possible as described in

"Case b / Adapted configuration".

***) If you replace the model, you will need to update the communications blocks to the latest

version.
