IC698CPE020 Product Description

The GE IC698CPE020 is a high-performance CPU module engineered for the PACSystems RX7i control platform, designed to serve as the central processing core within complex, multi-layer industrial automation architectures. As the computational backbone of the RX7i rack system, the IC698CPE020 coordinates signal acquisition, logic execution, communication arbitration, and diagnostic reporting across every functional layer of the control hierarchy — from field-level I/O to supervisory SCADA integration. Its architecture-first design philosophy makes it a preferred choice for engineers building scalable, redundant, and maintainable control systems in demanding industrial environments.

The IC698CPE020 does not operate in isolation — its value is fully realized when deployed within a coherent, layered automation platform. In a typical PACSystems RX7i architecture, the CPU module anchors the control layer while coordinating tightly with adjacent modules across every system tier.

At the power layer, the IC698PWR001 or IC698PWR002 rack power supply delivers regulated 5 VDC and 3.3 VDC rails to the backplane, ensuring the IC698CPE020 and all co-resident modules receive stable, noise-filtered power. Voltage transients or supply instability at this layer directly affect CPU scan cycle consistency, making power supply selection a critical architectural decision.

At the I/O layer, the IC698CPE020 manages both local rack I/O and remote expansion through dedicated I/O modules such as the IC694MDL340 (discrete output), IC694ALG220 (analog input), and IC694MDL660 (discrete input). These modules connect to field instruments, actuators, and sensors, with the CPU executing ladder logic or structured text programs to process real-time signal data. The backplane — typically the IC698CHS017 (9-slot) or IC698CHS113 (17-slot) — provides the physical and electrical interconnect between the CPU and all I/O modules, making backplane selection integral to system capacity planning.

At the communication layer, the IC698CPE020's onboard Ethernet port supports SRTP for peer-to-peer CPU communication, EGD (Ethernet Global Data) for high-speed broadcast exchange, and Modbus TCP for integration with third-party SCADA systems and HMI platforms. For installations requiring PROFIBUS DP or DeviceNet connectivity, the IC695PBM300 PROFIBUS master module or IC695NDR001 network interface module can be added to the same rack, extending the communication architecture without replacing the CPU.

At the HMI layer, the IC698CPE020 communicates natively with GE's Proficy HMI/SCADA iFIX or Cimplicity platforms via OPC or SRTP drivers, enabling real-time visualization of process variables, alarm management, and trend logging. For panel-mounted operator interfaces, third-party HMI terminals from Weintek, Proface, or Siemens can be integrated via Modbus TCP, leveraging the CPU's onboard Ethernet port without additional communication modules.

At the redundancy layer, the IC698CPE020 supports hot-standby CPU redundancy when paired with a second IC698CPE020 unit and the IC698CRE020 redundancy memory xchange module. This configuration ensures bumpless transfer of control in the event of a primary CPU fault, maintaining process continuity in critical applications such as power generation, chemical processing, and water treatment. The redundancy architecture also extends to I/O modules and communication paths, providing a fully fault-tolerant control platform.

At the protection layer, surge protection devices and UPS systems are recommended upstream of the IC698PWR001 supply to guard against grid-side transients. Within the rack, the CPU's built-in watchdog timer and self-diagnostic routines continuously monitor module health, scan cycle integrity, and memory consistency, generating fault codes accessible via Proficy Machine Edition for rapid troubleshooting.

At the maintenance layer, the IC698CPE020's flash-based firmware supports field upgrades without rack removal, and its CompactFlash slot (where applicable) enables program backup and restore operations. Paired with the IC698ACC004 battery backup module, the CPU retains program memory and retentive data registers through power interruptions, reducing recovery time after unplanned outages.

Power Generation & Utilities: In thermal and hydroelectric power plants, the IC698CPE020 manages turbine control sequences, generator protection interlocks, and grid synchronization logic. Its hot-standby redundancy capability ensures continuous operation during CPU maintenance windows, while EGD communication enables high-speed data exchange between multiple RX7i controllers managing different plant sections.

Oil, Gas & Petrochemical: Refinery and pipeline control systems rely on the IC698CPE020 for pressure regulation, flow control, and emergency shutdown (ESD) logic. The CPU's deterministic scan cycle and robust fault diagnostics support SIL-rated safety architectures when integrated with certified I/O modules and safety relays. Its wide operating temperature range and conformal coating options make it suitable for harsh process environments.

Water & Wastewater Treatment: Municipal water treatment facilities deploy the IC698CPE020 to control pump stations, chemical dosing systems, and filtration sequences across distributed remote I/O networks. Modbus TCP connectivity enables seamless integration with SCADA systems monitoring multiple treatment stages, while the CPU's redundancy support ensures uninterrupted operation of critical pumping infrastructure.

Automotive & Discrete Manufacturing: On high-speed assembly lines, the IC698CPE020 coordinates robotic cell controllers, conveyor systems, and quality inspection stations through high-density discrete I/O modules. Its fast scan cycle and deterministic execution support tight synchronization between multiple production zones, reducing cycle time variability and improving overall equipment effectiveness (OEE).

Mining & Metals: In mineral processing and smelting operations, the IC698CPE020 manages crusher control, conveyor sequencing, and furnace temperature regulation under high-vibration, high-dust conditions. Its industrial-grade construction and extended temperature tolerance support reliable operation in environments where consumer-grade controllers would fail prematurely.

Marine & Offshore: Shipboard automation systems use the IC698CPE020 for engine room control, ballast management, and cargo handling sequences. Its compact rack form factor and robust backplane design withstand the mechanical vibration and humidity levels characteristic of marine installations, while its Modbus TCP interface enables integration with vessel management systems.

Q1: Is the IC698CPE020 compatible with existing Series 90-70 racks and I/O modules? The IC698CPE020 is designed for the PACSystems RX7i platform, which uses a VME-based universal backplane (IC698CHS017 / IC698CHS113) that is physically and electrically compatible with legacy Series 90-70 I/O modules. GE's PACSystems migration architecture allows Series 90-70 I/O modules to be installed in RX7i racks alongside native RX7i modules, enabling a phased migration strategy that protects existing I/O investments while upgrading the CPU and communication infrastructure. Full compatibility should be verified against GE's PACSystems Compatibility Guide for specific module combinations.

Q2: What is required to implement hot-standby CPU redundancy with the IC698CPE020? Hot-standby redundancy requires two IC698CPE020 CPU modules (primary and secondary), one IC698CRE020 Redundancy Memory Xchange (RMX) module per CPU rack, and a dedicated fiber-optic or copper redundancy link between the two racks. Both CPUs must run identical firmware versions and program configurations. The IC698CRE020 continuously synchronizes memory state between primary and secondary CPUs, enabling bumpless transfer in under 10 milliseconds upon primary CPU fault detection. Redundant I/O and communication paths should also be configured to eliminate single points of failure at the system level.

Q3: What does the 12-Month Warranty cover, and how is inventory availability managed for long-term projects? Every IC698CPE020 unit supplied by NANKMOS is covered by a 12-Month Warranty against manufacturing defects and functional failures under normal operating conditions. Prior to shipment, each unit undergoes functional testing to verify CPU initialization, memory integrity, Ethernet communication, and backplane interface operation. For long-term projects requiring guaranteed inventory availability, NANKMOS maintains buffer stock of high-demand PACSystems RX7i components including CPU modules, power supplies, and I/O modules.
