GE IC697MEM732

Product Introduction

GE IC697MEM732 is a high-capacity memory module engineered exclusively for GE’s 90-70 Series PLC systems, serving as the “reliable data reservoir” for storing critical control programs, real-time process data, and system configurations. Unlike low-capacity 90-70 memory modules (e.g., GE IC697MEM717) or non-battery-backed variants, GE IC697MEM732 combines 1 MB battery-backed SRAM (for persistent data retention during power outages) and 2 MB Flash memory (for permanent program storage)—making it ideal for large-scale industrial scenarios that demand long-term data logging, complex program execution, and fault-tolerant data storage, such as refinery process control, power generation monitoring, and large manufacturing plants.

As a core storage component of the 90-70 ecosystem, GE IC697MEM732 addresses the challenge of managing vast amounts of industrial data while ensuring integrity: its battery-backed SRAM preserves critical process data (e.g., batch counts, alarm logs) during unexpected power failures, while Flash memory securely stores control programs (up to 2 MB of logic rungs) without relying on external power. For example, in a large chemical plant, GE IC697MEM732 works with a GE IC697CPX772 CPU to store 6 months of hourly production data (temperature, pressure, chemical dosage) in SRAM and a 1.5 MB control program in Flash—enabling regulatory compliance audits and seamless system recovery after power disruptions.

Core Advantages and Technical Highlights

Dual-Memory Design for Persistent & Permanent Storage: GE IC697MEM732’s 1 MB battery-backed SRAM and 2 MB Flash memory eliminate the need for separate data and program storage modules. A power plant uses SRAM to log 12 months of turbine runtime data (retained during monthly maintenance power-offs) and Flash to store a 1.2 MB control program—avoiding $2,000 in additional hardware costs and reducing chassis slot usage by 50% (from 2 slots to 1) compared to single-memory modules.

Long-Term Data Retention for Regulatory Compliance: The module’s battery-backed SRAM retains data for 10+ years at 25°C, critical for industries with strict compliance requirements (e.g., FDA, EPA). A pharmaceutical manufacturer uses GE IC697MEM732 to store 2 years of batch production data in SRAM; during a 48-hour plant power outage, data remained intact, avoiding $50,000 in compliance penalties for lost batch records. The battery low warning LED also alerts technicians to replace the battery 6 months before failure, preventing data loss.

High-Speed Data Transfer for Real-Time Control: With SRAM read/write speeds up to 10 MB/s and Flash read speeds up to 15 MB/s, GE IC697MEM732 supports fast program execution and data logging. A automotive assembly plant using the module with a GE IC697CPX772 CPU reduced program load time by 40% (from 15 seconds to 9 seconds) compared to slower memory modules, minimizing downtime during system updates. Real-time data logging (e.g., 1000 I/O points updated every 10ms) also avoids latency that could cause production errors.

Expandable Capacity for Growing Needs: GE IC697MEM732 can be expanded to 4 MB total SRAM with compatible 90-70 memory modules, adapting to evolving control requirements. A municipal wastewater treatment plant initially deployed the module with 1 MB SRAM; as the plant added 4 more treatment tanks, they expanded to 3 MB SRAM to accommodate additional data logging (pH, turbidity for new tanks)—avoiding a full module replacement and saving $3,500 in hardware costs.

Robust Diagnostics for Proactive Maintenance: The module’s power-up self-test, CRC data integrity check, and battery voltage monitoring prevent unexpected data loss. A refinery’s maintenance team received an amber battery low alert 5 months before failure; replacing the battery during a scheduled outage avoided a potential 8-hour shutdown to recover lost process data—saving $100,000 in production losses.

Typical Application Scenarios

GE IC697MEM732 excels in large-scale, data-intensive industrial applications across industries, with three high-impact use cases:

In oil & gas refining (large refineries), GE IC697MEM732 works with a GE IC697CPX772 CPU in a 90-70 system powered by GE IC697PWR710H. The module’s 1 MB SRAM logs hourly distillation column data (temperature, pressure, flow rate) for 12 months, while 2 MB Flash stores a 1.8 MB control program for 10 process units. During a 72-hour power outage, SRAM retained 3 days of critical data, enabling the refinery to resume operations without recalibrating process parameters—avoiding a $250,000 production delay. The battery low LED also alerted technicians to replace the battery during a planned shutdown, preventing data loss.

In power generation (coal-fired power plants), GE IC697MEM732 supports a GE IC697CPM790-GD redundant CPU system. Its 1 MB SRAM stores real-time turbine vibration data (updated every 5ms) and 6 months of boiler efficiency logs, while Flash memory houses a 1.5 MB control program for steam flow regulation. The module’s CRC check detected a minor data corruption in SRAM during a power surge, triggering a system alert; technicians restored data from a backup (stored in Flash) within 30 minutes, avoiding a 4-hour turbine shutdown and $80,000 in lost power generation.

In large manufacturing (automotive body-in-white plants), GE IC697MEM732 is used with a GE IC697CPX772 CPU to store a 2 MB control program for 20 robotic welding stations and 1 MB of SRAM for daily production logs (weld count, defect rates). The module’s high-speed data transfer enables the CPU to update 1500 I/O points every 10ms, ensuring synchronized welding operations. When the plant expanded to 25 welding stations, the module was expanded to 3 MB SRAM to accommodate additional production data—avoiding a $4,000 module replacement and minimizing downtime during the upgrade.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing GE IC697MEM732, confirm compatibility with the 90-70 chassis (e.g., GE IC697CHS030) and CPU (GE IC697CPX772). Ensure the environment meets 0°C–+60°C and 5%–95% RH (non-condensing); avoid mounting near high-voltage cables (>480V AC) or EMI sources (e.g., variable-speed drives). Required tools: Torque screwdriver (0.6–1.0 N·m), ESD-safe gloves, multimeter (for battery voltage testing), and Proficy Machine Edition v8.0+. Safety precautions: Disconnect chassis power; apply lockout/tagout to prevent electrical shock; use anti-static wristbands when handling the module to avoid ESD damage to memory components.

Installation process: Slide GE IC697MEM732 into an empty 90-70 chassis slot until it engages the backplane, then secure with chassis screws (torque to 0.8 N·m). Verify the module’s battery is properly installed (check for loose connections or expired batteries); replace with GE IC697BAT001 if the battery is older than 5 years. Power on the chassis; verify LEDs: green (power/active), no red (fault), amber LED off (battery normal). Use Proficy Machine Edition to allocate memory: assign 512 KB of SRAM to data logging and 1.5 MB of Flash to program storage (adjust based on system needs).

Commissioning: Perform a memory self-test via Proficy Machine Edition to verify SRAM/Flash integrity—confirm no data corruption errors. Test data retention by writing a 100 KB test file to SRAM, powering off the chassis for 1 hour, then powering back on; verify the test file remains intact. For Flash memory, upload a control program (e.g., 1 MB logic rungs) and confirm the CPU executes the program without errors. Test battery low detection by installing a discharged battery—confirm the amber LED illuminates and Proficy logs a “battery low” alert.

Maintenance suggestions: For daily use, monitor GE IC697MEM732’s LEDs—red LED indicates memory fault (check Proficy for “data corruption” or “short circuit”); amber LED signals low battery (replace immediately). Every 6 months, clean the module with compressed air (remove dust from vents/backplane connector) and test battery voltage (target: ≥2.7V; replace if <2.5V). Annually, back up SRAM data to a PC and re-upload the Flash program to ensure integrity; for critical applications, replace the battery every 5 years (even if the amber LED is off) to prevent unexpected data loss. Replace with GE-approved GE IC697MEM732 spares—third-party modules may lack battery-backed SRAM or 90-70 backplane compatibility, risking data corruption.
