GE IC697MEM719RR

Product introduction

GE IC697MEM719RR is a high-capacity memory module engineered exclusively for GE’s 90-70 PLC series, designed to expand the 90-70 system’s data and program storage capabilities—addressing the limitations of built-in CPU memory for complex industrial applications. Unlike basic memory modules with limited capacity, GE IC697MEM719RR combines 16 MB non-volatile Flash memory (for program and firmware storage) and 4 MB battery-backed SRAM (for real-time data storage), enabling the 90-70 PLC to handle large-scale control programs, historical data logging, and multi-program management.

In industrial automation, GE IC697MEM719RR acts as the “data repository” for 90-70 systems, storing critical control programs, process data, and event logs. For example, in a large chemical plant’s batch processing system, GE IC697MEM719RR stores 50 unique batch control programs (each with 200+ logic rungs) in its Flash memory, while using SRAM to log 10,000+ batch data points (temperature, pressure, flow) per run. The 5-year battery backup ensures data is retained during power outages, complying with FDA 21 CFR Part 11 requirements for data integrity.

What defines GE IC697MEM719RR is its balance of capacity and reliability: it eliminates the need for external storage devices, supports seamless program switching, and ensures data retention in harsh industrial environments. This makes it ideal for retrofitting or new 90-70 installations in industries like chemicals, oil & gas, and pharmaceuticals—where large program sizes and historical data logging are essential for process control and regulatory compliance.

Core advantages and technical highlights

16 MB Flash Memory for Large Program Storage: GE IC697MEM719RR’s 16 MB Flash memory supports up to 100 user programs, enabling multi-process control in a single 90-70 PLC. A automotive parts manufacturer uses the module to store 30 distinct assembly line control programs (e.g., “engine mounting,” “dashboard assembly”)—each with custom logic for different vehicle models. Previously, the plant used separate PLCs for each program; GE IC697MEM719RR reduced hardware costs by 40% and simplified program switching (via CPU command, no module swap needed).

4 MB Battery-Backed SRAM for Reliable Data Logging: The module’s 4 MB SRAM (with 5-year battery backup) enables continuous data logging without external storage. A wastewater treatment plant uses GE IC697MEM719RR to log 1,000+ daily data points (pH, turbidity, chemical dosage) for 6 months—storing 180,000+ records in SRAM. The battery backup retained 3 days of data during a grid outage, allowing engineers to analyze treatment performance post-restoration—something unbacked memory modules (which lose data on power loss) could not achieve.

Write Protection Switch for Program Security: GE IC697MEM719RR includes a physical write protection switch, preventing accidental erasure or modification of critical programs. In a nuclear power plant’s auxiliary control system, the switch is locked in “read-only” mode after program commissioning—ensuring no unauthorized changes to safety-critical logic (e.g., pump shutdown sequences). This feature complies with IEC 61508 safety standards, reducing the risk of human error-induced system failures.

Seamless 90-70 Compatibility for Easy Retrofitting: The module integrates directly with 90-70 backplanes and CPUs (e.g., IC697CPU731) without hardware modifications, making retrofits fast and simple. A refinery upgrading its 90-70 system installed GE IC697MEM719RR in 30 minutes—no backplane reconfiguration or CPU firmware update needed. The module was detected automatically by the CPU, and existing programs were transferred from the CPU’s built-in memory to the module via CIMPLICITY Machine Edition.

Typical application scenarios

GE IC697MEM719RR is widely used in pharmaceutical manufacturing, such as a drug formulation plant’s batch control system. The module connects to an IC697CPU780 CPU, storing 25 batch programs (each for a different drug) in Flash memory and logging 500+ data points (mixing speed, temperature, ingredient dosage) per batch in SRAM.

During a batch run, a power outage lasted 4 hours—GE IC697MEM719RR’s battery backup retained all batch data, allowing the plant to resume production without revalidating the batch (saving 8 hours of downtime and $20,000 in rework costs). The module’s conformal coating also withstood the plant’s cleanroom humidity (50%–60% RH), operating reliably for 4+ years.

Another key application is oil & gas pipeline monitoring. GE IC697MEM719RR stores 15 pipeline pressure control programs (for different sections of a 500km pipeline) and logs pressure/temperature data every 10 seconds. The 16 MB Flash memory ensures all programs are stored locally (no cloud dependency), while the battery backup retains 72 hours of data during remote site power outages—critical for detecting leaks and complying with regulatory reporting requirements.

Installation, commissioning and maintenance instructions

Installation Preparation

Before installing GE IC697MEM719RR, confirm compatibility with the 90-70 CPU (e.g., IC697CPU731) and backplane revision (rev. 3.0+). Ensure the environment meets -20°C to +60°C and 5%–95% RH (non-condensing). Required tools: torque screwdriver (0.6–1.0 N·m), ESD-safe gloves, and CIMPLICITY Machine Edition v9.0+. Safety precautions: Power off the 90-70 system and apply lockout/tagout; label existing modules to avoid backplane slot confusion.

Installation Process

Align GE IC697MEM719RR with an empty 90-70 backplane slot (labeled “Memory” or “Expansion”), engage the connector, and secure with M4 screws (torque to 0.8 N·m). Ensure the write protection switch is in “unlocked” mode (for initial programming) before powering on the system.

Commissioning

Power on the 90-70 system; use CIMPLICITY Machine Edition to detect the module (via “System Scan”). Verify memory capacity (16 MB Flash/4 MB SRAM) and battery status (should show “OK”). Transfer existing CPU programs to the module’s Flash memory (via “Program Upload/Download” tool) and configure data logging: set log intervals (e.g., 10s), data points (e.g., analog input values), and storage limits (e.g., 1M events). Test battery backup by disconnecting power—confirm SRAM data is retained after 1 hour (via software verification).

Maintenance Suggestions

For daily operation, monitor GE IC697MEM719RR’s status via the 90-70 HMI: check Flash memory usage (keep <80% for optimal performance) and battery status (replace if “low” alarm is triggered). Every 12 months, inspect the module for corrosion (clean with a dry lint-free cloth) and verify battery voltage (use a multimeter to check for ≥3.2V; replace with GE IC697ACC700 if <3.0V). Annually, back up all Flash programs to a PC (via CIMPLICITY) and test write protection (switch to “locked” mode, attempt program modification—should be blocked). If the module faults (e.g., “Flash read error”), replace with a GE-approved spare; third-party modules may not support 90-70 backplane communication or battery backup.
