Overview Manuals Specifications
 

Features:

  • Interface Between the RX3i Controllers and High-Speed Fiber-Optic Reflective Memory Network
  • Combines Capability of Deterministic Data Sharing with 2.1 Gbps Reflective Memory Technology
  • Operates in Conjunction with the IC695RMX128 and Standard RX3i PACSystems CPUs
The IC695CMX128 operates as the Control Memory Xchange Module in an RX3i PACSystems rack, providing reliable high-speed data sharing between PLCs and other computing devices within the reflective memory network. It continuously converts application data from RX3i controllers to regulated 2.1 Gbps optical signals and distributes this information through the fiber-optic ring network to support steady state operation of all distributed control nodes and I/O devices. Seamless data transfer is standard with the IC695CMX128, however using an optional **Redundant Fiber-Optic Ring Configuration will provide seamless switchover to a backup data path in the event of a primary network failure. The IC695CMX128 has made improvements in several areas over previous reflective memory designs in addition to incorporating universal 2.12 Gbaud fiber-optic transmission capability within the RX3i PACSystems family.

The IC695CMX128 provides essential data sharing functions common to the entire reflective memory network, and is a critical component of the high-speed communication path, directly affecting the accuracy and reliability of distributed control data exchange in the overall RX3i PACSystems network. One IC695CMX128 module is required per controller node depending on the desired data sharing topology and network redundancy level. The IC695CMX128 occupies only a single slot in the RX3i rack and is always located in the appropriate base unit slot (the dedicated communication interface position, the primary fiber-optic network connection point).

For Dual Redundant Fiber-Optic Ring applications, the RX3i PACSystems network requires a second IC695CMX128 module installed in the redundant node. In addition to standard single ring operation, the redundant configuration also performs automatic data path switchover. The RX3i dual ring configuration executes failover using the internal reflective memory circuitry specified in the CMX128 options. Using this method, the redundant fiber-optic system continually monitors the health of both data paths. If the system detects that the primary fiber-optic ring is no longer providing stable data transfer (outside configured latency/tolerance levels), it will automatically transfer the data load to the secondary ring path and place an event in the PLC Event Log.

The IC695CMX128 Control Memory Xchange Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
