Product Overview
The GE IC697VRM015 Reflective Memory Module is a high-performance Reflective Memory Module designed for the GE Fanuc Series 90-70 PLC platform. It enables deterministic, high-speed data sharing between multiple PLCs, industrial computers, distributed control systems (DCS), and real-time automation devices through a reflective memory network. By automatically replicating memory contents across connected nodes, the module ensures that every device on the network has immediate access to the same real-time process information.
Installed in a compatible Series 90-70 PLC rack, the IC697VRM015 communicates with the PLC CPU through the high-speed backplane while simultaneously exchanging data with other reflective memory nodes over a fiber-optic communication network. Unlike conventional Ethernet-based communication, reflective memory technology transfers data automatically at the hardware level without requiring complex messaging or polling, significantly reducing communication latency and CPU overhead.
The module is ideal for applications requiring deterministic data synchronization, including redundant control systems, turbine control, power generation, aerospace testing, simulation systems, process automation, synchronized machine control, distributed manufacturing, and high-speed data acquisition.
Designed for harsh industrial environments, the IC697VRM015 offers excellent resistance to electrical noise, vibration, temperature fluctuations, and continuous-duty operation. With dimensions of 243 × 41 × 156 mm and an approximate weight of 0.48 kg, it provides a compact and reliable solution for high-speed industrial data exchange.
