The Redundancy tab selects whether or not the PNS is to be redundantly controlled.

Figure 8: Select System Redundancy Parameters in PME

When the PNS supports PROFINET System Redundancy and is configured in an HSB CPU Redundancy
system, the Programmer defaults the Redundancy Mode parameter to HSB CPU Redundancy. Refer to the
PACSystems Hot Standby CPU Redundancy User's Manual, GFK-2308G or later, for detailed information on
setting up a Hot Standby Redundancy system.
When the PNS does not support PROFINET System Redundancy or is not configured in an HSB CPU
Redundancy system, the PNS Programmer defaults the Redundancy Mode parameter to None. This
selects simplex operation.
To configure a redundancy-capable PNS for simplex operation within an HSB CPU Redundancy system,
change the Redundancy Mode parameter from HSB CPU Redundancy to None.
Transfer List
All redundantly controlled I/O must be included in the CPU's I/O transfer list. Note that once the HSB CPU
Redundancy Mode is set, Proficy Machine Edition automatically expands the Primary CPU's input transfer
list to include all redundantly controlled PROFINET inputs as reference addresses are being assigned.
Proficy Machine Edition also automatically expands the Primary CPU's output transfer list to include all
redundantly controlled PROFINET outputs.
The configuration should be stored to both the Primary and Secondary racks before attempting to control
any I/O in the RX3i PNS.
Changing a Redundant PNS Configuration
Changes to the device's configuration on either the Primary while the Secondary is running or the
Secondary while the Primary is running will cause a Loss of Device I/O fault on the controller that is being
updated. The controller with the changed configuration will be prevented from re-connecting as long as a
non-matching connection exists with the device from any controller.
To make changes to the PNS configuration once the system is running, refer to the PACSystems Hot
Standby CPU Redundancy User's Manual, GFK-2308, and follow the procedure Download a Modified
Configuration to a Redundancy System – Stopping the Process.
