Configuring Hardware and Communication Connections STEP 7.pdf

Using a saved configuration as a basis for configuring a new station
Commissioning and Service
The PROFIBUS nodes determined online can be saved as a station configuration
(menu command PLC > PROFIBUS > Save PROFIBUS Online Configuration
As... ). Any changes made (in "Specify Module" or "Change Properties") are also
saved.
This newly saved configuration does not, however, contain any specific
configuration data for the DP master connected to the PROFIBUS. For this reason,
the DP masters are only shown symbolically, in a way similar to DP slaves.
You have the option of configuring DP masters at a later time and then replacing a
DP master determined online (and represented symbolically) with the newly
configured one.
Procedure:
1. Open the saved PROFIBUS online configuration.
2. Configure the same number of DP masters as the number of DP master
systems that were determined online
(the complete rack with CPU and PROFIBUS CP or CPUs with integral DP
interfaces).
3. Select one of the DP masters determined online that you want to replace with a
newly configured DP master.
4. Select the menu command Options > Assign Master.
5. In the dialog that is displayed, assign a configured master to a master that was
determined online.
6. Repeat steps 3 to 5 until all of the DP masters determined online are replaced
by configured ones.
