GE Fanuc's Data Sharing System
PACSystems Control Memory Xchange permits data sharing between up to 256 independent systems or nodes, allowing for plant-wide data transfer. Each controller or computer keeps a local copy of shared data for fast real-time use. It has a fiber-optic deterministic network that allows data transfer at rates up to 174 MB/sec, with node-to-node latency of 450 nsec. For example, a user can realize updates on 10,000 data tags in 1 msec.
