VMIPMC-5565
The GE Fanuc / VMIC VMIPMC-5565 / 5565PIORC Reflective Memory PMC Modules are the PCI mezzanine card (PMC) members of the GE Fanuc Embedded Systems VMIxxx-5565 family of Reflective memory (RFM) real-time network products. The other members of the family are VMIVME-5565, VME-compatible board, and VMIPCI-5565, the PCI-compatible board. All three of these products are network compatible, and may be integrated into a network in any combination.
This family of products allows computers, workstations, PLCs, and other embedded controllers with dissimilar operating systems or no operating systems at all to share data in real time.
To the local node, the Reflective Memory board appears as shared memory. Data can be written to or read from the memory by any level of software, including the application itself. Data written to the Reflective Memory in one node is transported by the network hardware to all other nodes, and placed in the same address on those node’s Reflective Memory boards. This transport of data is accomplished without the involvement of the processors on any node. By this system, all nodes on the network have a local copy of shared data available for immediate access.
