VMICPCI-1120  |  反射式存储器 PMC 模块  |  节点之间的透明数据传输

型号：VMICPCI-1120

特征：

高速、易于使用的光纤网络（串行 2.12 Gbaud）

多达 256 个节点

节点之间的透明数据传输

两个独立的DMA通道

错误管理和检测

VMICPCI-1120 反射式存储器 PMC 模块是 GE Fanuc 嵌入式系统VMICPCI-1120系列反射式存储器 （RFM） 实时网络产品的 PCI 夹层卡 （PMC） 成员。该系列的其他成员包括 VMIVME-5565（兼容 VME 的板）和 VMIPCI-5565（兼容 PCI 的板）。这三种产品都与网络兼容，并且可以任意组合集成到网络中。

VMICPCI-1120 该系列产品允许具有不同操作系统或根本没有操作系统的计算机、工作站、PLC 和其他嵌入式控制器实时共享数据。

对于本地节点，VMICPCI-1120 反射式内存板显示为共享内存。数据可以由任何级别的软件（包括应用程序本身）写入或读取。写入一个节点的反射式存储器的数据由网络硬件传输到所有其他节点，并放置在这些节点的反射式存储器板上的同一地址中。这种数据传输是在没有任何节点上的处理器参与的情况下完成的。通过这个系统，网络上的所有节点都有一个共享数据的本地副本，可以立即访问。

Model: VMICPCI-1120

Features:

High-speed, easy-to-use fiber optic network (serial 2.12 Gbaud)

Up to 256 nodes

Transparent data transfer between nodes

Two separate DMA channels

Error management and detection

VMICPCI-1120 Reflective Memory PMC module is a PCI sandwich card (PMC) member of GE Fanuc embedded system VMICPCI-1120 series Reflective memory (RFM) real-time networking products. Other members of the family include the VMIVME-5565 (VME-compatible board) and the VMIPCI-5565 (PCI-compatible board). All three products are compatible with the network and can be integrated into the network in any combination.

The VMICPCI-1120 family of products allows computers, workstations, PLCS and other embedded controllers with different operating systems or no operating systems at all to share data in real time.

For local nodes, the VMICPCI-1120 reflective memory board appears as shared memory. Data can be written or read by any level of software, including the application itself. Data written to the reflective memory of one node is transmitted by the network hardware to all other nodes and placed at the same address on the reflective memory boards of those nodes. This data transfer is done without the involvement of processors on any node. With this system, all nodes on the network have a local copy of the shared data that can be accessed immediately.
