M-8485S-507714 The is the PCI-based member of GE Fanuc Embedded Systems' family of Reflective Memory real time fiber-optic network products. Two or more s and other members of this family can be integrated into a network using standard fiber-optic cables. Each board in the network is referred to as a node. Reflective Memory allows computers, workstations, PLCs and other embedded controllers with different architectures and dissimilar operating systems to share data in real time. The VMIxxx-5565 family of Reflective Memory is fast, flexible and easy to operate. Data is transferred by writing to memory (SDRAM), which appears to reside globally in all boards on the network. Onboard circuitry automatically performs the transfer to all other nodes with little or no involvement of any host processor or system. A block diagram of the is shown in Figure 1 on page 15. Features • High speed, easy to use fiber-optic network (2.12 Gbaud serially) • PCI 64-bit 66MHz transfers • No host processor involvement in the operation of the network • Redundant Mode of Operation • Up to 256 nodes • Connectivity with multimode fiber up to 300 meters • Dynamic packet size, 4 to 64 bytes of data per packet • Transfer rate 47.1MB/s (4 byte packet) to 174 MB/s (64 byte packet) • 64MB or 128MB SDRAM Reflective Memory with parity • Two independent Direct Memory (DMA) channels • Configurable endian conversion for multiple CPU architectures on the same network Artisan Technology Group - Quality Instrumentation ...

Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture and intended use of this product. GE Fanuc Embedded Systems assumes no liability for the customer's failure to comply with these requirements. Ground the System To minimize shock hazard, the chassis and system cabinet must be connected to an electrical ground. A three-conductor AC power cable should be used. The power cable must either be plugged into an approved three-contact electrical outlet or used with a three-contact to two-contact adapter with the grounding wire (green) firmly connected to an electrical ground (safety ground) at the power outlet. Do Not Operate in an Explosive Atmosphere Do not operate the system in the presence of flammable gases or fumes. Operation of any electrical system in such an environment constitutes a definite safety hazard. Keep Away from Live Circuits Operating personnel must not remove product covers. Component replacement and internal adjustments must be made by qualified maintenance personnel. Do not replace components with power cable connected. Under certain conditions, dangerous voltages may exist even with the power cable removed. To avoid injuries, always disconnect power and discharge circuits before touching them. Do Not Service or Adjust Alone Do not attempt internal service or adjustment unless another person capable of rendering first aid and resuscitation is present. Do Not Substitute Parts or Modify System Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modification to the product. Return the product to GE Fanuc Embedded Systems for service and repair to ensure that safety features are maintained. Dangerous Procedure Warnings Warnings, such as the example below, precede only potentially dangerous procedures throughout this manual. Instructions contained in the warnings must be followed.
