Control Memory Xchange
The Benefits of Control Memory Xchange:
- Operation with large memory demands flow easily over the network
- Improves the data handling between systems
- Flexible programming models for real-time distributed control
- Your data is as current as your scan time, eliminating the need to factor in latency
In a fast paced world - speed rules. That is why GE Intelligent Platforms is please to bring you Control Memory Xchange. The CMX is built on reflective memory technology to allow multiple devices to share huge amounts of control data over a fiber-optic deterministic network. With a maximum network transfer rate of 2.1 GByte per second, it truly is the leader in deterministic communications.
The simple and powerful architecture of CMX enables global shared memory - providing real-time speed and deterministic performance withou the data collisions and latencies of other network technologies.
 
How Control Memory Xchange works:
- Operates in parrallel to main logic controller for minimal effect on scan time
- Writes data to shared memory, and immediately broadcasts to all other nodes on network
- Rates up to 174 Mbytes per second
- Node to node latency as low as 450 nanoseconds
- Each controller keeps a local copy of the shared data for fast, real time speed and performance
- Data transfer is automatic and easy, saving software code development
