GE PACSystems RX3i IC695CRU320-EZ Redundancy CPU

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:

▪ 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 exemptions identified in the Annex: 7(a), 7(c)-I, &7(c)-III.
