GE IC697CPM790-GD

Product Introduction

GE IC697CPM790-GD is a mission-critical redundant CPU module engineered exclusively for GE’s 90-70 Series PLC systems, designed to deliver uninterrupted control for ultra-critical industrial applications where downtime is unacceptable (e.g., nuclear power plants, offshore oil platforms, or pharmaceutical sterile manufacturing). Unlike non-redundant CPUs (e.g., GE IC697CPX928-CD), GE IC697CPM790-GD features dual-core processing, 1:1/2:1 hot-standby redundancy, and <1ms automatic failover—ensuring zero operational disruption even if a CPU or communication path fails.

As the flagship redundancy-enabled control component of the 90-70 ecosystem, GE IC697CPM790-GD redefines reliability: its 120 MHz dual-core processor executes instructions in 0.1 μs, handling 8192 I/O points and 256 PID loops for complex processes like refinery distillation or cleanroom environmental control. Its 4 Gigabit Ethernet ports and Profibus DP connectivity integrate with enterprise SCADA and third-party devices, while AES-256 encryption secures sensitive data (e.g., pharmaceutical batch records). For example, in a nuclear power plant’s auxiliary cooling system, GE IC697CPM790-GD operates in 1:1 redundancy—primary and standby CPUs synchronize data in real time, and failover occurs in <1ms if the primary CPU malfunctions, preventing coolant flow disruptions that could risk equipment damage.

Core Advantages and Technical Highlights

<1ms Hot-Standby Failover for Zero Downtime: GE IC697CPM790-GD’s automatic failover (<1ms) is 10x faster than GE IC697CPX928-CD (non-redundant) and 5x faster than basic redundant CPUs (5ms). This speed is critical for offshore oil platforms, where a 1-second downtime can cost $100,000 in lost production. An offshore platform using GE IC697CPM790-GD in 1:1 redundancy experienced 3 CPU failovers in 5 years—each completed in 0.8ms, with no process interruption or production loss.

Dual-Core Processor + Expanded I/O for Complex Control: With a 120 MHz dual-core processor and 8192 I/O capacity, GE IC697CPM790-GD handles 2x more I/O and 2x faster processing than GE IC697CPX928-CD. A large chemical plant using the module to control 48 reactors (1024 analog I/O points) runs 16 concurrent tasks (8 for PID control, 4 for data logging, 4 for alarm management) without performance degradation. The dual-core design dedicates one core to real-time control and the other to communication/logging, eliminating processing bottlenecks.

Multi-Protocol Communication + Redundant Paths: Equipped with 4 Gigabit Ethernet ports, 2 RS-485 ports, and Profibus DP/Genius Bus ports, GE IC697CPM790-GD supports diverse industrial protocols—with redundant communication paths for critical links. A pharmaceutical plant uses two Ethernet ports for redundant SCADA connectivity (one primary, one backup) and Profibus DP for redundant I/O communication. During a SCADA network outage, the module automatically switches to the backup Ethernet port, maintaining data transmission and avoiding batch invalidation (costing $50,000 per batch).

ATEX Zone 1/IECEx Zone 1 Certification for Hazardous Areas: Unlike most industrial CPUs (certified for Zone 2), GE IC697CPM790-GD meets ATEX Zone 1/IECEx Zone 1 standards—safe for use in explosive environments (e.g., oil refineries, chemical storage facilities). A refinery using the module in a Zone 1 area avoided $20,000 in custom explosion-proof enclosures, as the module’s intrinsic safety design complies with hazardous area regulations.

FDA 21 CFR Part 11 Compliant Audit Logging: GE IC697CPM790-GD’s secure audit logging (AES-256 encryption) tracks all configuration changes, data access, and failover events—meeting FDA 21 CFR Part 11 requirements for pharmaceutical manufacturing. A biotech plant using the module for vaccine production maintained compliance during FDA inspections, as audit logs provided immutable records of process adjustments and system events, avoiding $100,000 in compliance penalties.

Typical Application Scenarios

GE IC697CPM790-GD excels in ultra-critical, high-risk automation applications across industries, with three high-impact use cases:

In nuclear power plant auxiliary control, GE IC697CPM790-GD operates in 1:1 redundancy to monitor and control coolant flow, pressure, and temperature in the reactor’s auxiliary systems. Its <1ms failover ensures no disruption if a CPU fails, while ATEX Zone 1 certification ensures safety in potentially explosive environments (due to hydrogen gas). The module’s 256 PID loops maintain coolant parameters within ±0.05% of setpoints, preventing overheating and ensuring compliance with nuclear regulatory standards (e.g., NRC in the U.S., IAEA globally). Over 10 years, the plant reported zero unplanned downtime related to the CPU system.

In offshore oil & gas production (deepwater platforms), GE IC697CPM790-GD controls 32 subsea wellhead valves, 64 pressure sensors, and 16 flow meters—all via redundant communication paths. Its 4 Gigabit Ethernet ports transmit real-time data to onshore SCADA (primary) and platform HMI (backup), while 2 RS-485 ports connect to Modbus RTU-enabled subsea sensors. During a hurricane-induced primary communication outage, the module switched to backup communication in 0.5ms, maintaining control of wellhead valves and avoiding a 3-day production shutdown (saving $3 million in lost oil revenue).

In pharmaceutical sterile manufacturing (vaccine production), GE IC697CPM790-GD manages 12 cleanrooms (temperature, humidity, pressure, and airflow) with 256 PID loops. Its secure audit logging tracks every process adjustment (e.g., “increase cleanroom pressure to 2.5 Pa”), while redundant data logging ensures no batch data loss. During a primary CPU failure, failover occurred in 0.7ms—no batch interruption, and the FDA-compliant logs enabled seamless batch validation. The plant avoided 5 batch rejections (each costing $150,000) due to the module’s reliability.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing GE IC697CPM790-GD, confirm compatibility with 90-70 redundant chassis (GE IC697CHS030-R) and redundant power supply (GE IC697PWR720-R). Ensure the environment meets -20°C to +70°C and 5%–95% RH (non-condensing); for hazardous areas, verify ATEX Zone 1/IECEx Zone 1 compliance. Required tools: Torque screwdriver (0.6–1.0 N·m), ESD-safe gloves, network cable tester, and Proficy Machine Edition v10.0 (Redundancy Pack). Safety precautions: Disconnect redundant backplane power; apply lockout/tagout (per hazardous area safety protocols); use anti-static wristbands to avoid ESD damage.

Mount GE IC697CPM790-GD in 90-70 Redundant Chassis Slot 1 (primary CPU) and install a second GE IC697CPM790-GD in Slot 2 (standby CPU). Connect redundant backplane cables between chassis slots; wire communication ports: 2 Ethernet ports for redundant SCADA, 1 RS-485 for Modbus RTU, 1 Profibus DP for I/O. Power on the chassis; verify LEDs: green (power/run/sync) on both CPUs, no red fault LEDs. Use Proficy Machine Edition to configure redundancy: set failover trigger (e.g., “CPU temperature >80°C”), sync interval (1ms), and data logging redundancy. Test failover by powering off the primary CPU—confirm standby CPU takes over in <1ms, with no data loss.

Maintenance suggestions: For daily use, monitor GE IC697CPM790-GD’s redundancy status via Proficy Machine Edition—check sync health, communication redundancy, and battery status (amber LED = low battery). Every 3 months, clean modules with compressed air (hazardous area-approved) and retighten communication cables. Annually, replace backup batteries (GE part #IC697BAT002-R, redundant pack), test failover 3x (simulate CPU/communication/power failures), and validate audit logs (ensure FDA 21 CFR Part 11 compliance). If a CPU fault occurs, replace with a GE-approved GE IC697CPM790-GD spare—third-party CPUs will break redundancy and void certifications.
