Hot-Standby CPU Redundancy using PROFINET I/O Parameters
The Redundancy tab selects whether or not the PNS is redundantly controlled.
Since the VersaMax PNS supports PROFINET System Redundancy when it is configured in an
HSB CPU Redundancy system, the VersaMax PNS Programmer automatically selects
redundant control by setting the Redundancy Mode parameter to "HSB CPU Redundancy".
When the VersaMax PNS is not configured in an HSB CPU Redundancy system, the VersaMax
PNS Programmer automatically selects simplex operation (non- redundant control) by setting
the Redundancy Mode parameter to None.
If desired, the user may configure a redundancy-capable PNS within an HSB CPU Redundancy
system for simplex operation (non-redundant control) by changing the Redundancy Mode
parameter on the Redundancy tab form "HSB CPU Redundancy" to "None"
