Procedure for configuring an I-slave
This section shows how to configure an I-slave in STEP 7 based on the example of a
CPU 1512SP-1 PN. The procedure for the CPUs from S7-1500 with CM 1542-5/CP 1542-5
and for the CPU 1510SP-1 PN with CM DP is the same.
To configure an I-slave, follow these steps:
1. Drag a CPU 1512SP-1 PN from the hardware catalog to the network view.
2. Open the device view of the CPU.
3. Double-click on the CM DP communications module in the hardware catalog.
STEP 7 creates the CM DP in the device view.
4. Select the PROFIBUS interface of the CM DP communications module.
5. In the Inspector window in the area navigation, select the "Operating mode" entry and
enable the "DP slave" check box.
6. Now you can select the DP master in the "Assigned DP Master" drop-down list.
Once you have selected the DP master, the networking and the DP master system
between both devices are displayed in the network view.

Note
Operation using a GSD file
If you operate an I-slave using a GSD file, you should not select the "Test, commissioning
and routing" check box.
Create a DP subnet on the PROFIBUS interface of the I-slave.
Result
You have configured an I-slave.
