Connecting field devices to a redundant bus system

Redundant connection of field devices with SIMATIC PDM
Some field devices allow redundant connection in the automation system. If information about
this feature is stored in the device description, SIMATIC PDM can recognize this.
You can determine whether this feature can be configured in the "Properties" dialog box of the
process device network view. With these objects, you will see a "Redundancy" area in the
"Communication" tab.
Procedure
1. Configure an object for each of the bus addresses of a field device that can be connected
2. Open the "Object Properties" dialog for the configured master field device in the process
3. Open the "Communication" tab.
4. In the "Redundancy" section, click "Select Object".
5. Select the partner field device.
6. Click "OK".

redundantly.
Note
Applying the configuration
You are allowed to fully configure one object only (this is referred to as the "master field
device" in the following). The other object must not contain substructures. This also applies
if redundant partners have been configured in HW Config. In the case of remote I/O (e.g.,
P+F LB/FB RemoteIO), therefore, you should configure the modules in HW Config only
after the redundancy selection.
For the second object, you only need to configure the bus address (this is referred to as
the "partner field device" from this point forward). You can display only the master field
device on the partner field device. You can find information on this in the section
""Communication" tab (Page 174)".
device network view.
The list of configured devices opens.
The list of configured devices closes. The "Enable redundancy" check box is selected in
the "Redundancy" section and the partner field device is displayed.
