5.4.6 How to configure the Y Link
Introduction
The Y Link consists of two IM 153-2 interface modules and a Y coupler. The Y Link creates a
gateway from a redundant DP master system to a non-redundant DP master system.
The following describes how to install and configure the Y Link.
You can find configuration examples in the section "Gateway between redundant and non-
redundant PROFIBUS DP (Page 80)".
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 View > Catalog menu command.
The hardware catalog opens.
3. In the current PCS 7 profile, double-click "PROFIBUS DP" and then "DP/PA Link".
4. Select the IM 153-2 interface module whose hardware catalog description is "Y Link".
5. Drag the IM 153-2 interface module to one of the two PROFIBUS DP lines.
6. Enter the PROFIBUS address in the "Properties - PROFIBUS Interface IM 153-2" dialog
box and click "OK".
7. Click on "Interface module for PROFIBUS DP" in the "Define Master System" dialog box
and click "OK".
