PROFINET Controller Parameters (Media Redundancy Tab)
By default, a PNC is not set up for Media Redundancy. If the system will use Media Redundancy
(see chapter 6 for more information), open the Media Redundancy Tab and select either Client or
Manager:
If the PNC will be a Media Redundancy Client, click on Ring Port 1 and Ring Port 2 to choose the
module ports and Domain Name that will be used.
If the PNC will be a Media Redundancy Manager, edit the Ring Port settings as above. You can also
change the Default Test Interval in the range of 1 to 1000ms and the Test Monitoring Count (2 to
10). For the Media Redundancy Manager, the Domain Name can be edited by typing over the
default name.
Note: In an MRP ring with a large number of clients, storing a configuration that causes all clients
to reconfigure (for example, changing the Domain Name) may generate a large number of
Loss/Addition of Device faults. This is expected behavior and all devices should automatically return
to operational.
