GE IC698CPE020-JX High Performance Central Processing Unit (CPU) Module

Description

The GE IC698CPE020-JX is a high-performance central processing unit (CPU) module from the GE Fanuc PACSystems RX3i series, widely used in demanding industrial automation applications. It powers real-time control systems in industries such as manufacturing, material handling, process automation, and energy management. This module is essential where fast, reliable processing of complex control logic, data acquisition, and machine coordination is required, making it suitable for controlling complex machinery and continuous processes. Engineers rely on the IC698CPE020-JX for its ability to seamlessly integrate into distributed control systems (DCS) and programmable logic controller (PLC) networks, delivering precise execution of programmed instructions in mission-critical environments. It fits perfectly in applications needing high-speed data processing plus robust communications for integrated system control.

The IC698CPE020-JX is a CPU module designed to fit within the GE PACSystems RX3i hardware architecture. As the brains of the control system, it executes control logic, processes inputs and outputs signals via connected modules, and maintains system diagnostics and communications. Running on a 700 MHz Pentium III floating-point processor, it produces fast computation speeds allowing efficient control of complex operations. The module features embedded Ethernet ports and serial communications supporting Modbus RTU, SNP, and VME protocols, enabling easy integration with various programmable devices and supervisory control systems. Its onboard memory includes 10 MB of battery-backed RAM and 10 MB of non-volatile flash memory for program storage, accommodating large, sophisticated control programs commonly used in industry.

Technically, the GE IC698CPE020-JX excels in responsiveness and reliability. It offers a Boolean execution speed of approximately 0.14 ms per 1000 Boolean contacts or coils, doubling throughput compared to its predecessor models. Built to operate continuously in a temperature range up to 60°C (with optional cooling), it sustains stable operation in harsh industrial conditions. The module supports up to 512 configurable program blocks, each with a maximum size of 128 KB, allowing intricate program design. Its dual embedded 10/100 Mbps auto-sensing Ethernet ports facilitate efficient, flexible communications with multiple networked devices simultaneously. The CPU also supports real-time web-based monitoring with up to 16 combined web server and FTP connections, enhancing system transparency and remote diagnostics. Its robust VME64 backplane compatibility ensures compatibility with previous system modules and facilitates system scalability for evolving industrial needs.

The IC698CPE020-JX integrates smoothly with other RX3i series components, including the IC698CHS030 backplane, IC695ALG550 analog input modules, IC695MDL740 discrete I/O modules, IC695CPU320 CPU modules for redundancy, and IC697MDL740 discrete output modules. These components collectively form scalable, customizable control systems adaptable to diverse industrial automation needs.

Proper installation requires settling the CPU module firmly on a VME64-compatible backplane with correct electrical and cooling provisions. Adequate ventilation and stable power supply must be maintained to ensure reliability, particularly when operating near the upper temperature limits. Firmware and diagnostic updates should be regularly applied to leverage new features and maintain cybersecurity. Routine inspection of communication ports and memory status indicators facilitates proactive maintenance, reducing unplanned downtime.
