The "Redundancy mode" tab in the configuration tool selects whether or not the PNS to be
redundantly controlled.
When it is configured for "HSB CPU Redundancy", the PROFINET System Redundancy
feature in PNS gets enabled. This causes the PNS to accept redundant PROFINET SR-AR
connections (primary and backup) from the controllers.
When it is configured for "None", the PROFINET System Redundancy feature in PNS gets
disabled. This causes PNS to accept only one AR connection from the controller (simplex
operation).
3.2.1.2 Media Redundancy Parameters
By default, the PNS is not set up for Media Redundancy. If the PNS will be a Media
Redundancy Client, select the PNS ports that will be used for Ring Port 1 and Ring Port 2,
and the MRP Domain. The MRP Domain name is used to assign MRP Clients to the media
redundancy manager (MRM) for the network ring.
Media Redundancy = None (Media redundancy Disabled).
Media Redundancy = Client (Media redundancy Enabled).
3.2.1.3 Module Parameters
Fatal Error Action
If a fatal error occurs, the PNS either blinks an error code on its LEDs and sets the modules
into fail safe state or Gets restarted based on the configuration.
Apply Failsafe = PNS blinks an error code on the LEDs
Auto Restart = PNS Restarts
