GE IC698RMX016 PACSystems RX7i Redundant Memory Xchange 16MB Memory

الوصف

The GE IC698RMX016 is a Redundant Memory Xchange (RMX) module for the PACSystems RX7i series of Programmable Logic Controllers (PLCs). Its primary function is to provide a high-speed, dedicated link for data synchronization in critical, high-availability control systems.

Key Features and Specifications

• Redundancy Link: The IC698RMX016 is primarily used to create a bumpless transfer in a redundant RX7i system. It provides a path for the primary and standby CPUs to continuously transfer and synchronize data. This ensures that if the primary CPU fails, the standby CPU can take over immediately without any interruption to the process being controlled.
• Reflective Memory Network: When not being used for CPU redundancy, the module can operate as a node on a reflective memory network. In this configuration, data written to the module on one node is automatically and immediately replicated across all other nodes on the network. This allows for deterministic data sharing among multiple PLCs and other computing devices.
• Shared Memory: The “016” in the part number indicates it has 16 MB of SDRAM user memory. This memory is used for storing and sharing large amounts of data between the connected devices.
• High-Speed Fiber Optic Network: The module uses a high-speed 2.12 Gbaud fiber optic network for communication. This provides extremely fast data transfer and, importantly, offers immunity to electrical noise, making it ideal for electrically noisy industrial environments. The connectors are LC type fiber optic ports.
• Software Configuration: All node parameters and redundancy configurations are set via software using Proficy Machine Edition, which eliminates the need for physical jumpers or switches.
• Hot Swap Capability: The module is designed to be hot-swappable, which means it can be replaced while the system is powered on, minimizing downtime during maintenance.

Applications

The IC698RMX016 is a crucial component in mission-critical applications where system failure is not an option. It is used in:

• Hot Standby CPU Redundancy Systems: The most common application, where it provides the high-speed data link between a primary and a backup CPU to ensure uninterrupted operation in industries like power generation, oil and gas, and water treatment.
• High-Speed Data Sharing: In non-redundant configurations, it can be used to provide deterministic data sharing among multiple PLCs and other computing devices on a high-speed fiber optic network.
