Configuring IRT Communication
5.9.2 Configuring Media Redundancy
Configuring Media Redundancy for an Entire IO Device
Requirements
Procedure
All data in the communications relationship between the IO controller and the IO
device are transmitted in a media-redundant manner.
• A topology with two independent paths has been configured.
• The IO device supports the function.
• A redundancy manager has also been configured.
1. In HW Config, select the relevant IO device.
2. In the detail view of the IO device, double-click "Interface Submodule" for the
IO device to open the property sheet.
3. Select the "Media Redundancy" tab.
Configuring Media Redundancy for an Individual Address Area in a Controller-
Controller Communication Relationship (Direct Data Exchange)
Requirements
Procedure
Media-redundant transmission is configured for each address area between sender
and receiver.
• A topology with two independent paths has been configured.
• A redundancy manager has also been configured.
1. Double-click "Interface Submodule" for the IO controller (e.g. IF1).
2. Select the "Receiver" tab.
3. Create a new row ("New" button) and assign a sender to the receiver.
4. In the "Receiver Properties" dialog box, select the "Media Redundancy" check
box.
