GE IC695CRU320 Redundancy CPU

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
