The PACSystems* RX3i Redundancy CPU can be used to perform real time control of machines, processes, and material handling systems. The CPU communicates with the programmer and HMI devices via a serial port using SNP Slave protocol. It communicates with I/O and smart option modules over a dual backplane bus that provides:
GE IC695CRU320 Redundancy CPU
High-speed PCI backplane for fast throughput of new
advanced I/O.
▪ Serial backplane for easy migration of existing
Series 90*-30 I/O.
Features
▪ Hot standby (HSB) redundancy. Two redundant units
make up a redundancy system. Each unit requires one
Redundancy CPU (IC695CRU320) and a redundancy
Memory Xchange module (IC695RMX128/228) configured
as a redundancy link.
▪ Contains 64 Mbytes of battery-backed user memory and
64 Mbytes of non-volatile flash user memory.
▪ Provides access to bulk memory via reference table %W.
▪ Configurable data and program memory.
▪ Programming in Ladder Diagram, Structured Text,
Function Block Diagram, and C. Refer to PACSystems RX7i
& RX3i CPU Programmer’s Reference Manual, GFK-2950.
▪ Supports auto-located Symbolic Variables that can use
any amount of user memory.
▪ Reference table sizes include 32Kbits for discrete %I and
%Q and up to 32K words each for analog %AI and %AQ.
▪ Supports most Series 90-30 modules and expansion
racks. For a list of supported I/O, Communications,
Motion, and Intelligent modules, refer to the PACSystems
RX3i System Manual, GFK-2314F or later.
▪ Supports up to 512 program blocks. Maximum size for a
block is 128KB.
▪ CPU firmware may be upgraded in the field.
▪ CPU supports firmware upgrades of modules in its
backplane.
▪ Two serial ports: an RS-485 serial port and an RS-232
serial port.
▪ Ethernet communications via the rack-based Ethernet
Interface module (IC695ETM001). For details on Ethernet
capabilities, refer to PACSystems RX7i & RX3i TCP/IP
Ethernet Communications User Manual, GFK-2224.
▪ Time Synchronization to SNTP Time Server on Ethernet
network when used with Ethernet Release 5.0 or later.
▪ Compliant with EU RoHS Directive 2002/95/EC using the
following exemp

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
