Hot Standby CPU Redundancy Features

For details on the configuration and operation of a Hot Standby CPU redundancy system, refer to the PACSystems

Hot Standby CPU Redundancy User’s Manual, GFK-2308.

? Supports single and redundant Ethernet remote I/O LANs through Ethernet Network Interface Unit (ENIU)

modules

? Supports simplex and redundantly controlled PROFINET remote IO (requires firmware version 8.00 or later)

? Survives any one single point of failure

? Bumpless switching

o Synchronized CPUs

o One scan switching

o Transfer data size up to 2Mbytes; selected in CPU hardware configuration and in variable properties

? Supports two redundancy communications links

? Online repair of failed component

? Online programming

? Redundancy Memory Xchange Module

o Manual toggle switch for role switching, which transitions control from the active unit to the backup unit

o Redundancy status LEDs

? Application-initiated role switching to switch the active unit to backup status

? Redundancy status bits and message logging

? Memory error checking and correction (ECC) single bit correcting and multiple bit checking

? Background diagnostics

HSB Control Strategy

The HSB control strategy has the following characteristics:

? Active unit does not automatically switch to primary on resynchronization

? Critical control data plus all redundant outputs must be included in the output data transfer

? Bumpless switchover from active unit to backup unit This product is intended for use with the RX3i system. Its components are considered open equipment (having live

electrical parts that may be accessible to users) and must be installed in an ultimate enclosure that is

manufactured to provide safety. At a minimum, the enclosure shall provide a degree of protection against solid

objects as small as 12mm (fingers, for example). This equates to a NEMA/UL Type 1 enclosure or an IEC60529 IP20

rating providing at least a pollution degree 2 environment. For details about installing RX3i rack systems, refer to

PACSystems RX3i System Manual, GFK-2314.
