GE EPSCPE100-ABAC PACSystems RSTi-EP Standalone PAC

Overview

The EPSCPE100-ABAC (CPE100) from GE PACSystems RSTi-EP is a compact, high-speed programmable automation controller engineered for deterministic machine and process control. Unlike traditional rack-based PLC architectures, this controller integrates CPU, networking, and I/O coordination into a single industrial-grade unit, making it suitable for space-constrained control cabinets and distributed automation systems.

Designed for real-time execution and industrial Ethernet communication, the controller supports complex logic execution while maintaining predictable scan times in demanding environments.

Controller Architecture

At the core of the EPSCPE100-ABAC (CPE100) is a 1 GHz industrial processor optimized for deterministic control tasks. The controller provides 1 MB of non-volatile user application memory, sufficient for multi-task automation programs, motion coordination, and protocol handling without performance degradation.

Four integrated Ethernet interfaces allow physical network separation between control, I/O, supervisory systems, and diagnostics, reducing latency and improving system resilience.

Networking and Protocol Support

The controller supports multiple industrial Ethernet standards commonly used in modern automation systems. Dual-LAN capability enables redundant or segmented network architectures, while ring-topology support improves uptime in distributed I/O installations.

Supported communication technologies include Profinet for real-time I/O exchange, Modbus TCP for device integration, and EtherNet/IP for interoperability with third-party equipment.

Programming Environment

The EPSCPE100-ABAC (CPE100) is programmed using GE Proficy Machine Edition. Engineers can develop applications using IEC-compliant languages such as Ladder Logic and Structured Text, as well as C# for advanced control strategies, data processing, and custom logic execution.

This multi-language capability allows seamless migration from traditional PLC programming to more advanced software-centric automation designs.

Technical Specifications

Reliability and Industrial Design

The controller incorporates conformal coating on critical circuitry to improve resistance to humidity, dust, and airborne contaminants. Internal power path redundancy enhances operational stability in environments with fluctuating supply conditions. These features make the controller suitable for continuous operation in industrial control panels and decentralized automation nodes.

Typical Applications

The EPSCPE100-ABAC (CPE100) is commonly deployed in:

Machine-level control systems
Distributed Profinet I/O architectures
Packaging and assembly automation
Process skids and modular plants
OEM equipment requiring compact controllers
