GE IC698CPE010-JU

Description

Product Overview and Description

The GE IC698CPE010-JU is a powerful Central Processing Unit (CPU) module for the GE Fanuc RX7i series of Programmable Automation Controllers (PACs), part of the legacy but still widely deployed PACSystems family. This CPU is the brain of a high-performance control system, designed for demanding industrial applications that require significant processing power, large memory capacity, and robust networking capabilities. The suffix “-JU” in the GE IC698CPE010-JU model number typically denotes a specific revision level or region-specific firmware/hardware variant. As a key component of the RX7i platform, this CPU module executes user-programmed logic, manages communication with local and remote I/O, and interfaces with plant-wide networks like Ethernet and Genius Bus. The GE IC698CPE010-JU is engineered for reliability in harsh environments and is a cornerstone for complex automation solutions in industries like power generation, water treatment, and oil & gas. Understanding the capabilities and architecture of this specific CPU is essential for system design, programming, and long-term maintenance.

Key Advantages and Features

The GE IC698CPE010-JU offers a blend of high performance and legacy compatibility, making it a key component for upgrading or maintaining existing systems. A major advantage is its support for the deterministic Genius Bus communication, allowing for high-speed, peer-to-peer data exchange and distributed I/O control, which was a hallmark of GE’s systems. It provides a robust and mature programming environment through Emerson’s (formerly GE) Proficy Machine Edition software. The CPU features a dual-port RAM for high-speed data exchange with co-processor modules (like motion controllers). Its robust design ensures reliable operation in environments with temperature extremes, vibration, and electrical noise. The GE IC698CPE010-JU also supports online editing and downloading, allowing for program modifications with minimal process disruption. The “-JU” variant ensures specific regional compliance or firmware features required for certain markets or applications.

Application Scenarios and Use Cases

This CPU is deployed in large-scale, critical infrastructure and heavy industrial applications. In power generation, it is used for turbine control, boiler control, and balance-of-plant systems in fossil fuel and hydroelectric plants. For water and wastewater treatment, it serves as the master controller for large treatment facilities, managing complex processes across vast sites with remote I/O. In the oil & gas sector, the GE IC698CPE010-JU controls pipeline compressor stations, offshore platform safety systems, and refinery processes. Mining and metals operations use it to control mineral processing plants and rolling mills. It is also found in large material handling systems, such as airport baggage handling or port automation, where its ability to manage thousands of I/O points and coordinate multiple subsystems is essential.

Comparison with Competing Products

The GE IC698CPE010-JU competes in the high-end process and machine control segment against other large-scale PLC/PAC CPUs such as the Siemens SIMATIC S7-400 series (e.g., CPU 416), Rockwell Automation ControlLogix 1756-L7x series, and Schneider Electric Modicon Quantum CPUs. Compared to modern controllers, the RX7i platform and the IC698CPE010-JU utilize an older VME bus architecture versus the more contemporary PCI or proprietary high-speed backplanes. Its strength lies in its installed base, proven reliability, and deep integration with GE’s Genius I/O system, which competitors do not natively support. When compared to its successor, the newer RX3i platform (PCI-based), the RX7i with the IC698CPE010-JU offers higher maximum I/O capacity and different performance characteristics, often being selected for very large, existing installations.

Selection Guidelines and Important Notes

Selection Advice:

1. System Compatibility: Ensure the GE IC698CPE010-JU is compatible with the existing or planned RX7i chassis, power supply, and I/O modules (both VME and Genius Bus).

2. Memory and Performance Assessment: Evaluate the application’s size (program memory, data memory) and scan time requirements to confirm this CPU is adequately sized. Oversizing is recommended for future expansion.

3. Communication Needs: Plan the communication architecture. The embedded Ethernet and serial port may suffice, or additional communication modules (for Genius Bus, Ethernet networks, or other fieldbuses) may be required.

4. Firmware Version: Verify the firmware version of the specific “-JU” unit. It must be compatible with the Proficy Machine Edition software version you are using.

5. Legacy Integration: If integrating with existing Series 90-30 or 90-70 systems, this CPU provides strong migration paths and compatibility features.

Important Precautions:

• Battery Maintenance: The lithium battery is critical for memory retention. Monitor its status LED and replace it proactively according to the manufacturer’s schedule (typically every 2-5 years) with the correct type to prevent program loss.

• Proper Handling: Always follow ESD (electrostatic discharge) precautions when handling the CPU module. Install it in the correct slot (usually slot 1) of the RX7i chassis.

• Firmware Updates: Update firmware with extreme caution and only when necessary. Always have a full, verified backup of the application program before starting. Ensure uninterrupted power during the update.

• Heat Management: The CPU generates heat. Ensure adequate ventilation and clearance in the control cabinet, and that any chassis cooling fans are operational.

• Program Backup: Maintain multiple, dated backups of the application program and hardware configuration offline. The loss of this file can lead to extensive downtime.

• Stop/Run Key: Use the physical key switch on the CPU to change modes. Be aware that switching to STOP halts all logic execution, which may stop a process.
