GE Fanuc IC695CRU320 RX3i Redundancy CPU Module

PACSystems* RX3i Redundancy CPU Overview

The PACSystems RX3i Redundancy CPU* offers real-time control capabilities for machines, processes, and material handling systems. It utilizes SNP Slave protocol for communication with the programmer and HMI devices via a serial port. Communication with I/O and smart option modules occurs over a dual backplane bus, featuring a high-speed PCI backplane for advanced I/O throughput and a serial backplane for easy migration of existing Series 90*-30 I/O.

Features

• Hot Standby (HSB) Redundancy: The redundancy system comprises two redundant units, each requiring a Redundancy CPU (IC695CRU320) and a redundancy Memory Xchange module (IC695RMX128/228) configured as a redundancy link.

• Memory Capacity: The CPU contains 64 Mbytes of battery-backed user memory and 64 Mbytes of non-volatile flash user memory, accessible via bulk memory reference table %W.

• Programmable Memory: Configurable data and program memory, supporting programming in Ladder Diagram, Structured Text, Function Block Diagram, and C.

• Symbolic Variables: Supports auto-located Symbolic Variables utilizing user memory.

• Reference Table Sizes: Reference table sizes include 32Kbits for discrete %I and %Q and up to 32K words each for analog %AI and %AQ.

• Module Support: Supports most Series 90-30 modules and expansion racks. For a detailed list of supported modules, refer to the PACSystems RX3i System Manual.

• Program Blocks: Supports up to 512 program blocks, with a maximum block size of 128KB.

• Field Upgradability: Firmware of both CPU and modules in its backplane can be upgraded in the field.

• Serial Ports: Equipped with two serial ports: an RS-485 port and an RS-232 port.

• Ethernet Communications: Supports Ethernet communications via the rack-based Ethernet Interface module (IC695ETM001), with time synchronization to SNTP Time Server on Ethernet network.

• RoHS Compliance: Compliant with EU RoHS Directive 2002/95/EC, with specified exemptions identified in the Annex.
