How to configure the redundant interface for the I/O device

Introduction
Once you have integrated the interface module (IM 153-2 for ET 200M, IM 152-1 for ET 200iSP)
as hardware in the distributed I/O device, the component is made known to the system in
SIMATIC Manager with HW Config or NetPro.
Requirements
● The PCS 7 project with a SIMATIC H station is open in SIMATIC Manager.
● A redundant DP master system is configured for the SIMATIC H station in HW Config.
Procedure
1. In the component view, select the SIMATIC H station and double-click the "Hardware"
object in the detail window.
HW Config opens.
2. If the hardware catalog is not visible, select the menu command View > Catalog.
The hardware catalog opens.
3. Double-click on "PROFIBUS DP" in the current PCS 7 profile.
