Application Scenarios
In a large automotive assembly plant, a body-in-white welding line consists of hundreds of robots, welding controllers, and material handling systems that must be synchronized with millisecond precision. A central PLC coordinates safety gates, clamp sequencing, and robot enable signals. The GE Fanuc IC697CPX928-FE CPU is the core of this control system. Its fast 928 MHz processor scans thousands of I/O points and executes complex coordination logic within a tight scan time, ensuring the line’s cycle time is met. Its integrated Ethernet port allows it to communicate directly with Human-Machine Interfaces (HMIs) for operator control, exchange production data with a supervisory system, and perform remote programming and diagnostics. It solves the pain points of requiring high-speed deterministic control, reliable networking, and the processing power to handle large, complex ladder logic and structured text programs.
Technical Principles and Innovative Values
Innovation Point 1: Integrated High-Speed Ethernet for Converged Networks. The inclusion of a standard 10/100 Mbps Ethernet port directly on the CPU (signified by -FE) was a significant step. It allowed the Series 90-70 to move beyond proprietary networks (like Genius) for higher-level communication. This enabled seamless integration with plant-wide systems for data collection (MES/SCADA), easy connection to standard Ethernet-based HMIs, and simplified programming/diagnostics over a network. It facilitated the convergence of information technology (IT) and operational technology (OT) networks at the controller level.
Innovation Point 2: Powerful Processing for Complex Control Strategies. With its 928 MHz processor and large memory footprint, the IC697CPX928-FE could handle not just large volumes of simple ladder logic, but also complex programming elements like structured text, subroutine libraries, and advanced function blocks. This power allowed it to implement sophisticated control algorithms, extensive data handling, and mathematical computations previously requiring separate computing devices, consolidating functionality into a single, robust PLC platform.
Innovation Point 3: Scalable and Robust Architecture for Demanding Environments. The CPU is the anchor of the scalable Series 90-70 platform. It manages a distributed I/O system (Genius LAN) that could span long distances, allowing for a modular and physically decentralized control architecture ideal for large facilities like automotive plants or water treatment facilities. The hardware was designed for high reliability and deterministic performance in harsh industrial environments, ensuring consistent operation where uptime is critical.
Application Cases and Industry Value
Case 1: Municipal Water Treatment Plant Master Controller. A water treatment facility used a GE Fanuc IC697CPX928-FE as the master controller for its filter backwash and chemical dosing processes. The CPU coordinated dozens of remote I/O drops via Genius LAN across the vast plant site. Its Ethernet port connected to a SCADA system, providing real-time tank levels, valve statuses, and pump metrics to operators in the central control room. The plant manager highlighted the system’s unwavering reliability over a decade of 24/7 operation. When a pump sequencing logic needed optimization, engineers could connect via Ethernet from their office to download the updated program, minimizing downtime. The CPU’s power and connectivity provided a future-proof backbone for the critical infrastructure.
Case 2: High-Speed Packaging Line Synchronization. A food and beverage company operated a high-speed bottling and packaging line where a conveyor, filler, capper, and labeler had to be perfectly synchronized. The IC697CPX928-FE CPU, with its fast scan time, managed the high-speed registration and interlocking of all machines. Its integrated Ethernet allowed it to receive production orders from a plant ERP system and send OEE (Overall Equipment Effectiveness) data back for analysis. The engineering team valued the CPU’s deterministic performance, which eliminated timing jitters that caused occasional missed caps, and its networking capability, which streamlined integration with the wider factory IT system, boosting overall line efficiency.

Installation, Maintenance, and Full-Cycle Support
Installation involves inserting the CPU module into the left-most slot (Slot 0) of the Series 90-70 rack, connecting power, and attaching Ethernet and serial cables. Configuration is done via the programming software (PME or VersaPro), where the hardware is configured, and the control logic is developed and downloaded. Critical steps include setting the correct IP address for the Ethernet interface and configuring the Genius network parameters.
Routine maintenance involves monitoring the CPU status via its front-panel LEDs (RUN, OK, I/O, COMM faults) and through the programming software. The battery on the CPU (or in the rack) that retains memory must be monitored and replaced periodically (every 2-5 years) to prevent program loss. Keeping backups of the application program and configuration is essential. If a CPU fails, it can be replaced by installing a new unit and downloading the program from a backup.
