IC698CRE030 (PACSystems RX7i Redundant CPU Module)

Product Description The IC698CRE030 is a high-performance hot standby redundant central processing unit designed for Emerson PACSystems RX7i VME64-based PLC system. Optimized for mission-critical industrial fields, it features stable master-slave automatic switchover function to minimize production downtime and supports complicated large-scale process control logic calculation.

Description

Model Interpretation

IC698 stands for PACSystems RX7i VME platform series, CRE represents Control Redundancy CPU, and 030 refers to specified hardware configuration, operating frequency and memory specification.

Technical Parameters

Processor and Performance Specifications

Core processor is Intel Pentium M running at 600MHz. Boolean instruction execution speed reaches approximately 0.05ms per 1K boolean instructions. Equipped with 64MB battery-backed RAM and 64MB nonvolatile flash memory for program and parameter storage. The module supports maximum 32768 discrete input/output points and up to 32768 analog register words, allowing up to 512 independent user program blocks. Hot standby switching completes within one program scan cycle, typical switch time less than 100ms.

Communication Configuration

Dual independent 10/100Mbps Ethernet RJ45 ports supporting Modbus TCP, SNP and EtherNet/IP protocols. One RS232/RS485 serial port compatible with Modbus RTU and SNP slave communication. One USB2.0 interface dedicated to online programming and file download. The unit connects with peripheral I/O modules via standard VME64 backplane bus and retains compatibility with traditional Genius remote I/O system.

Electrical Features

Rated operating input power sourced from VME backplane: +5V at 3.2A, +12V and -12V with low auxiliary current consumption. Built-in lithium backup cell maintains RAM data and real-time clock during power outage, with typical service life 3 to 5 years. Onboard hardware real-time clock with daily deviation lower than 2 seconds.

Mechanical and Environmental Index

Single VME slot dimension: 40mm × 100mm × 160mm, unit weight around 0.8kg. Normal working ambient temperature ranges from 0°C to +60°C, extended operating range -20°C ~ +70°C; storage temperature -40°C ~ +85°C. Relative working humidity between 5% and 95% without condensation. Certified with UL, CE, CSA and ATEX industrial safety approvals.

Front Panel Indication and Software Functions

Front-mounted status LEDs include CPU OK, RUN, Output Enable, Force, Battery Low and System Fault indicators. Supports four standard IEC programming languages: Ladder Diagram, Structured Text, Function Block Diagram and C language programming. Complete internal self-diagnosis and system fault record storage functions available.

Core Functions

Realize automatic hot standby redundant operation after pairing two identical IC698CRE030 modules without extra auxiliary hardware. Execute complex multitask control algorithms and floating-point arithmetic operations for large process automation systems. Establish redundant Ethernet networking to connect HMI, SCADA and third-party field devices. Realize seamless access to RX7i local VME I/O and legacy Genius distributed I/O modules. Prevent program and parameter loss via dual nonvolatile storage design against unexpected power cut.

Applications

Applied in critical petrochemical and oil & gas process control requiring uninterrupted operation. Widely deployed in thermal power plants, hydropower facilities and municipal water treatment projects. Used for heavy industry automatic production lines including metallurgy and automotive assembly. Suitable for important infrastructure control such as tunnel ventilation and large building automation systems.

Usage & Maintenance Instructions

Install the module into standard VME64 rack slot and fix front panel screws securely. Configure redundant master-slave parameters via Proficy Machine Edition programming software. Replace internal backup lithium battery every three to five years to avoid data loss. Check front panel LED status and wiring connection regularly during routine maintenance. Compatible with all standard RX7i series I/O modules and incompatible with RX3i, Series90-30 and Series90-70 products.
