Product Overview
The GE IC698CMX016 Control Memory Switching Module is a high-performance Control Memory Switching Module designed for GE Fanuc PACSystems RX7i programmable automation controller (PAC) systems. It enables reliable memory synchronization and redundancy management between redundant CPU systems, ensuring continuous controller operation and minimizing process interruptions during controller switchover.
As a key component in high-availability RX7i architectures, the IC698CMX016 manages the exchange and synchronization of control memory between redundant controllers. It continuously transfers critical application data, process variables, controller status information, and memory images to ensure that the standby CPU maintains an identical operating state to the active controller. In the event of a controller fault or planned maintenance, the redundant CPU can assume control with minimal disruption to the automation process.
Designed for mission-critical industrial applications, the IC698CMX016 features robust industrial construction capable of operating reliably in environments subject to electrical noise, vibration, and continuous operation. Its deterministic communication performance supports high system availability and improved operational reliability.
With dimensions of 165 × 96 × 50 mm and an approximate weight of 0.64 kg, the GE IC698CMX016 is suitable for installation in compatible PACSystems RX7i racks.
Typical applications include power generation, oil and gas production, chemical processing, pharmaceutical manufacturing, water and wastewater treatment, mining, transportation infrastructure, manufacturing automation, and other industrial processes requiring controller redundancy.
