EPSCPE100-ABAA Product Description

The GE EPSCPE100-ABAA is a high-performance central processing unit engineered for the PACSystems RX3i control platform — one of GE's most widely deployed modular PLC architectures in industrial automation. Designed to serve as the computational core of a distributed or centralized control system, the EPSCPE100-ABAA delivers deterministic scan-cycle execution, robust memory management, and seamless contextual integration across multi-rack, multi-network automation environments. Whether deployed in a greenfield installation or as a validated replacement in an existing RX3i backplane, this CPU module maintains full backward compatibility with the broader PACSystems ecosystem, ensuring minimal disruption to production continuity.

At NANKMOS, every EPSCPE100-ABAA unit undergoes pre-shipment functional testing and is supplied with a 12-Month Warranty, supporting procurement teams, maintenance engineers, and system integrators who require verified, shelf-ready components for critical infrastructure projects.

The EPSCPE100-ABAA is not a standalone device — it is the architectural anchor of a complete PACSystems RX3i control platform. Its value is fully realized when integrated within a layered automation hierarchy that spans the control layer, I/O layer, communication layer, power layer, HMI layer, execution layer, protection layer, and maintenance layer.

At the control layer, the EPSCPE100-ABAA operates in conjunction with the IC695RMX128 redundancy memory exchange module to support hot-standby CPU redundancy configurations, ensuring zero-interruption failover in mission-critical processes. Paired with a secondary EPSCPE100-ABAA or compatible RX3i CPU, the redundancy architecture maintains synchronized program state across both controllers, eliminating single points of failure at the processing core.

At the I/O layer, the CPU communicates directly with mixed analog and discrete I/O modules mounted on the same IC695CHS016 16-slot universal backplane. Modules such as the IC695ALG600 analog input module and IC695MDL740 discrete output module are scanned deterministically within each CPU sweep cycle, maintaining signal integrity across high-density I/O configurations. For remote I/O expansion, the EPSCPE100-ABAA supports RX3i remote drop architectures via the IC695ETM001 Ethernet transmitter module, extending the I/O footprint across geographically distributed control cabinets without additional CPU resources.

At the communication layer, the CPU's onboard Ethernet port supports SRTP and Modbus TCP natively, enabling direct integration with SCADA systems, historian servers, and MES platforms. For legacy serial device connectivity, the IC695CMM002 serial communications module can be added to the same backplane, providing RS-232/RS-485 multi-drop capability for field instruments, drives, and third-party controllers. EGD (Ethernet Global Data) peer-to-peer exchange allows the EPSCPE100-ABAA to share real-time process data with other PACSystems CPUs across the plant network without SCADA mediation.

At the power layer, the IC695PSA040 AC power supply module provides regulated 3.3V and 5V backplane power with built-in diagnostics, supporting the CPU and all co-resident I/O modules. For DC-powered installations, the IC695PSD040 offers equivalent capacity with 24VDC input, suitable for battery-backed or solar-assisted control panels in remote field applications.

At the HMI layer, the EPSCPE100-ABAA integrates seamlessly with GE's Proficy HMI/SCADA iFIX and Cimplicity platforms via Ethernet, as well as with third-party HMI panels using Modbus TCP drivers. Operator interface terminals connected to the CPU's serial port can provide local process visualization and parameter adjustment without network dependency, supporting maintenance access in isolated control rooms.

At the execution layer, variable-frequency drives, servo controllers, and motor starters receive discrete and analog command signals from the RX3i I/O modules under CPU program control. The deterministic scan cycle of the EPSCPE100-ABAA ensures that motion sequencing, interlock logic, and process control loops execute with consistent timing, critical for coordinated multi-axis or multi-drive applications in packaging lines, conveyor systems, and pump stations.

At the protection layer, the CPU's onboard fault table and diagnostic registers provide real-time visibility into module health, I/O faults, communication errors, and power anomalies. Integration with the IC695ETM001 allows remote fault notification to SCADA or maintenance management systems, enabling predictive maintenance workflows and reducing unplanned downtime.

At the maintenance layer, the EPSCPE100-ABAA supports online program editing and live variable monitoring via Proficy Machine Edition, allowing engineers to modify logic, tune PID parameters, and force I/O states without halting production. Flash memory-based program storage eliminates battery dependency for program retention, reducing scheduled maintenance intervals and improving long-term system reliability.

Manufacturing & Discrete Automation: In automotive assembly, electronics manufacturing, and metal fabrication, the EPSCPE100-ABAA manages multi-station sequencing, robotic cell interlocking, and quality inspection triggers. Its high I/O capacity and deterministic scan cycle support complex ladder logic programs with hundreds of simultaneous interlock conditions, maintaining production throughput without scan-cycle jitter.

Power Generation & Utilities: In thermal power plants, hydroelectric stations, and substation automation, the CPU's redundancy capability and Modbus TCP protocol support enable integration with protection relays, energy meters, and DCS systems. Hot-standby configurations ensure continuous turbine control and grid synchronization even during CPU module replacement or firmware updates.

Oil, Gas & Petrochemical: In pipeline control, compressor stations, and refinery process units, the EPSCPE100-ABAA's robust operating temperature range and CE/UL certification support deployment in classified electrical areas. EGD peer-to-peer communication enables real-time data exchange between field PLCs and central control rooms without SCADA polling overhead, reducing communication latency in time-sensitive process control loops.

Water & Wastewater Treatment: Municipal water treatment facilities and industrial effluent systems rely on the RX3i platform for pump sequencing, chemical dosing control, and SCADA integration. The EPSCPE100-ABAA's Ethernet connectivity and Modbus TCP support enable direct integration with flow meters, level transmitters, and remote telemetry units across geographically distributed pump stations.

Mining, Metallurgy & Heavy Industry: In ore processing, smelting, and rolling mill applications, the CPU's high I/O capacity and modular expansion capability support large-scale process control programs with thousands of I/O points. Remote I/O drop architectures extend control coverage across large plant footprints without additional CPU hardware, reducing system complexity and maintenance overhead.

Marine & Offshore: Shipboard automation, ballast control, and offshore platform safety systems benefit from the EPSCPE100-ABAA's compact form factor, DIN rail mounting, and wide operating temperature range. Redundancy configurations ensure continuous propulsion control and safety interlock monitoring even in high-vibration, high-humidity marine environments.

Q1: Is the EPSCPE100-ABAA compatible with existing PACSystems RX3i backplanes and I/O modules already installed in my control cabinet? Yes. The EPSCPE100-ABAA is fully compatible with all IC695 series universal backplanes (7, 12, and 16-slot configurations) and the complete range of RX3i analog, discrete, and specialty I/O modules. No backplane or I/O module replacement is required when substituting an existing RX3i CPU with the EPSCPE100-ABAA, provided the firmware revision of the replacement unit is equal to or higher than the original. NANKMOS can advise on firmware compatibility prior to shipment upon request.

Q2: Can the EPSCPE100-ABAA be configured for CPU redundancy, and what additional hardware is required? Yes. Hot-standby CPU redundancy is supported using the IC695RMX128 redundancy memory exchange module, which synchronizes program state and I/O data between the primary and secondary CPUs in real time. Both CPUs must be mounted in separate RX3i racks connected via the RMX128 fiber-optic link. Switchover time is typically less than one scan cycle, ensuring seamless failover without process interruption. NANKMOS maintains stock of both the EPSCPE100-ABAA and IC695RMX128 to support complete redundancy kit procurement.

Q3: What warranty and post-shipment support does NANKMOS provide for the EPSCPE100-ABAA? Every EPSCPE100-ABAA supplied by NANKMOS is covered by a 12-Month Warranty from the date of shipment. Prior to dispatch, each unit undergoes pre-shipment functional testing to verify power-on operation, communication port integrity, and backplane interface continuity. In the event of a warranty claim, NANKMOS provides direct technical support and expedited replacement to minimize control system downtime. For ongoing maintenance planning, NANKMOS recommends maintaining at least one spare EPSCPE100-ABAA in your critical spares inventory, particularly for systems operating in continuous or safety-critical processes.
