Product Introduction

The GE IC697MSC802 is a high-capacity memory storage module designed as an upgraded variant of the GE IC697MSC801 for GE’s Series 90-70 PLC platform. Engineered to address the growing demand for large-scale data logging and complex program storage, it doubles the total storage capacity of its predecessor—offering 16 MB (8 MB NVRAM + 8 MB Flash)—while enhancing durability and data retention capabilities.

As a critical storage component for high-performance Series 90-70 CPUs like the IC697CPU789, the GE IC697MSC802 enables the CPU to handle extended-duration data logging (e.g., years of process trends) and store multi-layered control programs (e.g., integrated safety logic + production sequencing) without memory bottlenecks. Its dual-battery design extends NVRAM data retention to 12 years, and hot-swappable batteries eliminate data loss risks during replacement. The module maintains full compatibility with the Series 90-70 backplane and Proficy Machine Edition software, making it a seamless upgrade for existing systems using the IC697MSC801—ideal for industries like oil and gas, power generation, and large-scale manufacturing where data volume and retention are mission-critical.

Core Advantages and Technical Highlights

Doubled storage capacity for large-scale applications: The GE IC697MSC802 offers 16 MB of total storage (8 MB NVRAM + 8 MB Flash), twice the capacity of the GE IC697MSC801. This expansion is transformative for applications requiring long-term data retention—for example, a power plant can log generator performance data at 1-second intervals for over 3 years in the 8 MB NVRAM, compared to 1.5 years with the IC697MSC801. The 8 MB Flash memory also accommodates complex programs, such as integrated PLC-open motion control logic paired with safety interlock code, which would exceed the storage limits of lower-capacity modules.

Enhanced data retention with dual hot-swappable batteries: Unlike the single-battery GE IC697MSC801, the GE IC697MSC802 features dual 3.6 V lithium batteries with hot-swappable functionality. This design extends NVRAM data retention to 12 years (2 years longer than its predecessor) and allows maintenance teams to replace batteries one at a time while the module is powered—eliminating the data loss risk associated with single-battery replacement. For instance, in a chemical refinery where process data cannot be interrupted, technicians can swap a low battery without shutting down the system, ensuring continuous compliance with regulatory logging requirements.

Wider environmental tolerance and industrial certification: The GE IC697MSC802 boasts a broader operating temperature range (-10°C to 65°C vs. 0°C to 60°C for the IC697MSC801) and higher vibration (8 g peak) and shock (40 g peak) resistance. It also adds ATEX Zone 2 certification, making it suitable for hazardous environments like oil refineries or chemical plants where flammable gases may be present. An additional moisture resistance coating protects internal components from humidity-related damage, ensuring reliable performance in coastal or high-moisture facilities (e.g., wastewater treatment plants) where the IC697MSC801 might be vulnerable.

Burst data transfer for efficient large-file handling: The GE IC697MSC802 supports burst data transfer over the Series 90-70 backplane, enabling the IC697CPU789 to read/write large files (e.g., 5 MB program backups or 10 MB historical data logs) up to 50% faster than the IC697MSC801. This feature is critical for applications requiring rapid data retrieval, such as real-time analytics in automotive plants—where engineers need to access months of production data within seconds to identify efficiency bottlenecks—or emergency troubleshooting in power plants, where fast access to historical turbine data can prevent equipment failure.

Typical Application Scenarios

Long-term process data logging in nuclear power plants: Nuclear power facilities rely on the GE IC697MSC802 to store decades of critical process data (e.g., reactor coolant temperature, radiation levels) for regulatory compliance and safety audits. The module’s 8 MB NVRAM can log 1-second interval data for over 3 years, while its 12-year battery retention ensures data remains intact even during extended power outages. ATEX Zone 2 certification makes it safe for use in controlled hazardous areas, and dual hot-swappable batteries allow maintenance without data loss—critical for facilities where downtime or data gaps violate nuclear safety standards. The IC697CPU789 accesses the module’s memory to feed real-time data to SCADA systems and archive historical trends, ensuring compliance with NRC (Nuclear Regulatory Commission) requirements.

Complex program storage in automotive OEMs: Large automotive original equipment manufacturers (OEMs) use the GE IC697MSC802 to store integrated control programs for multi-line production facilities. The module’s 8 MB Flash memory accommodates complex logic—including robotic arm synchronization, quality inspection algorithms, and MES integration code—that would exceed the 4 MB Flash limit of the GE IC697MSC801. For example, a plant with 5 assembly lines can store a unified program (with line-specific parameters) in the GE IC697MSC802, allowing the IC697CPU789 to switch between lines without reloading software. Burst data transfer enables fast program updates during scheduled maintenance, reducing downtime from hours to minutes.

Hazardous environment data logging in offshore oil platforms: Offshore oil platforms require rugged memory solutions, and the GE IC697MSC802 meets this need with its ATEX Zone 2 certification, moisture resistance coating, and wide temperature range (-10°C to 65°C). The module stores real-time data from wellhead sensors (pressure, flow rate, gas composition) in its 8 MB NVRAM, with dual batteries ensuring data retention during platform power fluctuations. Unlike the GE IC697MSC801, it withstands the high vibration from offshore winds and waves (8 g peak vs. 5 g) and resists saltwater moisture—ensuring reliable performance for years. The IC697CPU789 uses the module’s data to optimize well production and trigger emergency shutdowns if hazardous conditions arise.
