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.
