Product Introduction

The GE IC697MSC801 is a dedicated memory storage module designed for GE’s Series 90-70 PLC platform, engineered to expand the data and program storage capacity of Series 90-70 CPUs—such as the high-performance IC697CPU789—while ensuring long-term data retention. As a critical storage component, it combines non-volatile RAM (NVRAM) and Flash memory to address two key needs: real-time data storage (via NVRAM) and permanent program/configuration storage (via Flash), eliminating the risk of data loss during power outages or system restarts.

Unlike built-in CPU memory, which often has limited capacity, the GE IC697MSC801 provides 8 MB of additional storage (4 MB NVRAM + 4 MB Flash), enabling the CPU to handle large-scale data logging (e.g., production metrics, sensor trends) and store complex control programs without memory constraints. Its seamless integration with the Series 90-70 backplane allows the CPU to access stored data at 10 Mbps—ensuring no performance lag for real-time applications. The module’s battery-backed NVRAM (10-year retention) and permanent Flash make it ideal for industrial environments where data integrity and long-term storage are non-negotiable, such as manufacturing plants, oil refineries, and water treatment facilities.

Core Advantages and Technical Highlights

Hybrid storage design for dual-purpose utility: The GE IC697MSC801’s combination of 4 MB NVRAM and 4 MB Flash memory sets it apart from single-type memory modules. NVRAM (battery-backed) is optimized for real-time data storage—such as dynamic process variables (temperature, pressure) or production counts—ensuring data is retained even if the PLC loses power. Flash memory, by contrast, provides permanent storage for control programs, configuration files, and firmware backups—eliminating the need to reload programs after a system reset. This hybrid design means the GE IC697MSC801 can replace two separate modules (NVRAM and Flash), reducing rack space usage and system cost by up to 30%.

Long-term data retention with replaceable battery: The GE IC697MSC801’s NVRAM is backed by a replaceable 3.6 V lithium battery, providing up to 10 years of data retention without external power. Unlike non-replaceable battery modules, this design allows maintenance teams to extend the module’s lifespan by simply replacing the battery (when the LED indicator signals low power) instead of replacing the entire module—reducing long-term operational costs. For example, in a water treatment plant, the module can store 5 years of flow rate data in NVRAM; when the battery nears end-of-life, a quick replacement ensures no historical data is lost.

Seamless Series 90-70 integration and plug-and-play functionality: Designed exclusively for the Series 90-70 platform, the GE IC697MSC801 plugs directly into any available rack slot and communicates with the CPU (e.g., IC697CPU789) via the 10 Mbps backplane. It requires no complex configuration—GE’s Proficy Machine Edition software automatically detects the module and maps its memory to the CPU’s address space, allowing engineers to start storing data within minutes. This plug-and-play functionality eliminates the need for manual memory addressing or third-party software, reducing commissioning time and minimizing the risk of configuration errors.

Industrial-grade durability for harsh environments: The GE IC697MSC801 is built to withstand the rigors of industrial operations, with a wide operating temperature range (0°C to 60°C), resistance to vibration (5 g peak) and shock (30 g peak), and compliance with UL 508 and IEC 61131-2 standards. Unlike consumer-grade memory modules, it is protected against electromagnetic interference (EMI) and dust ingress—ensuring reliable performance in environments like automotive factories (where welding equipment generates EMI) or oil refineries (where dust and temperature fluctuations are common). This durability translates to a mean time between failures (MTBF) of over 200,000 hours, minimizing unplanned downtime.

Typical Application Scenarios

Manufacturing execution systems (MES) in automotive plants: In automotive assembly lines, the GE IC697MSC801 works with the IC697CPU789 to store real-time production data—such as vehicle identification numbers (VINs), assembly step completion status, and quality inspection results—in its NVRAM. The module’s 4 MB NVRAM capacity can log data for up to 10,000 vehicles per shift, while its Flash memory stores the assembly line control program and MES integration configurations. If the plant experiences a power outage, the battery-backed NVRAM retains critical production data, preventing gaps in MES reporting and ensuring the assembly line can resume operation without rework.

Process data logging in chemical refineries: Chemical refineries rely on the GE IC697MSC801 to store historical process data—including reactor temperature, pressure, and chemical composition—for regulatory compliance and troubleshooting. The module’s NVRAM logs data at 1-second intervals (a requirement for EPA and OSHA reporting), while its Flash memory stores the PID control program and safety interlock configurations. The IC697CPU789 accesses the module’s memory via the backplane to retrieve data for SCADA visualization and trend analysis; if a process deviation occurs, engineers can review historical data from the GE IC697MSC801 to identify the root cause.

Water treatment plant configuration and data retention: In water treatment facilities, the GE IC697MSC801 stores the plant’s control program (e.g., filtration and disinfection sequences) in its Flash memory and real-time water quality data (e.g., pH levels, turbidity) in its NVRAM. The module’s battery-backed NVRAM ensures water quality data is retained during power outages, while its Flash memory prevents the control program from being corrupted by voltage spikes. The IC697CPU789 uses the module’s memory to run the treatment process and send data to the plant’s SCADA system—ensuring compliance with drinking water standards and enabling operators to track long-term water quality trends.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing the GE IC697MSC801, power off the Series 90-70 main rack and wear an anti-static wristband to prevent electrostatic damage to the module’s memory chips. Ensure the rack (e.g., GE IC697RACK10) has an available slot (slots 2-20, as slot 1 is reserved for the CPU) and is powered by a compatible supply (e.g., GE IC697PWR711). Gather tools: a screwdriver (to secure the module to the rack), a torque wrench (to tighten rack screws to 4.5 N·m), and a PC with Proficy Machine Edition software (for verification). Verify the environment: temperatures 0°C-60°C, humidity 5%-95% non-condensing, and no exposure to corrosive gases or excessive dust—conditions that could damage the module’s battery or memory chips.

Commissioning steps:

Insert the GE IC697MSC801 into the rack slot, aligning the backplane connector, and secure it with screws (torque to 4.5 N·m).

Power on the rack and confirm the module’s power LED turns green (powered), backplane LED turns blue (communicating with CPU, e.g., IC697CPU789), and battery LED turns green (battery good).

Launch Proficy Machine Edition, connect to the CPU, and verify the software detects the GE IC697MSC801—it will display the module’s memory capacity (8 MB) and battery status.

Configure memory usage: Use the software to assign NVRAM for real-time data (e.g., map sensor data to NVRAM address 0x0000-0xFFFF) and Flash for program storage (e.g., save the control program to Flash address 0x10000-0x1FFFF).

Test data retention: Store a test file (e.g., a small program snippet) in the module’s Flash and a test value (e.g., sensor reading = 25°C) in NVRAM. Power off the rack for 5 minutes, then power on and verify the test file and value are still present.

Maintenance suggestions:

Daily: Inspect LEDs—green power, blue backplane, and green battery indicate normal operation. A yellow battery LED signals low battery (replace within 30 days to avoid data loss).
