Media Redundancy Tab
By default, a PNC is not set up for Media Redundancy. If the system will use Media
Redundancy (refer to Chapter 11, PROFINET Redundant Media 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 then select the 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 10 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:
GFK-2816F
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.
