How to configure redundancy for OS servers on the engineering station

Introduction
Carry out the following configuration tasks on the Engineering Station. The description for the
OS server is used here.
Validity
The procedure described in this section applies to the following servers:
● OS server
● Maintenance server
Requirements
● The PCS 7 project is open in SIMATIC Manager.
● You configured two SIMATIC PC stations in HW Config for operation as master and standby
OS servers.
Configuring WinCC Explorer "Redundancy"
Note
Settings in steps 5 and 6: The settings are adopted automatically from the configuration in
SIMATIC Manager. It may be necessary to adapt settings if projects have been copied or if
you configure in a different order from the one recommended for PCS 7.
1. In the component view of SIMATIC Manager, select the OS in the OS server and select
the menu command Edit > Open Object.
The WinCC Explorer opens.
2. Select the menu command Editor > Redundancy > Open in WinCC Explorer.
The "Redundancy" application opens.
3. Select the "Activate redundancy" check box.
4. In the "General" tab, select the "Default Master" check box if you want to set the OS server
as the default master.
Note
Make sure that only one of the two OS servers is the "default master" and that this option
is not selected for both of the OS servers in the "Redundancy" dialog box. Problems may
otherwise occur during redundancy failover of OS clients.
5. In the "Redundant Partner Server" field, enter the computer name of the redundant OS
server. You can also use the "Browse" button to select an appropriate server from the
network.
