VMIC/GE Fanuc 系列由通用电气开发，由该公司的工业自动化部门生产，但这些产品后来被 Abaco Systems 购买和开发。

VMIVMVE-5576 接口模块允许在 256 个独立系统之间以高达 6.2 MB 的速率共享数据。

VMIC/GE Fanuc 系列中的反射式存储器板设计为可针对共享和保留的数据进行配置，具有高达 256 KB 至 1 MB 的板载 SRAM。

集成到这些 VMIC/GE Fanuc 模型中的反射存储器被编程为通过将其发送到字节寄存器来同时中断多个节点。这些信号同步系统进程。

【英文介绍】

This module is one of the VMIC/GE Fanuc modules and is designated as the VMIVME-5576 unit of the series. The board is designed as a reflective memory board capable of transmitting data. It does this by recording it to the onboard RAM. The reflective memory concept of these boards provides a very fast and efficient way to share data between distributed computer systems.

The VMIC/GE Fanuc series was developed by General Electric and manufactured by the company's Industrial automation division, but these products were later purchased and developed by Abaco Systems.

The VMIVMVE-5576 interface module allows data sharing between 256 independent systems at rates of up to 6.2 MB.

The reflective memory boards in the VMIC/GE Fanuc family are designed to be configured for both shared and retained data, with up to 256 KB to 1 MB of onboard SRAM.

The reflected memory integrated into these VMIC/GE Fanuc models is programmed to interrupt multiple nodes simultaneously by sending it to byte registers. These signals synchronize system processes.

Node interrupts can track data. This ensures that data is received and then interrupts are enabled once received. The VMIVME-5576 unit is built so that no initialization is required before the interrupt function is used.

Features:

● High-speed fiber optic network

● Node spacing 2000 meters, up to 256 nodes

● Error detection

● Redundant transmission mode for error suppression

●A24: A32: D32: D16: D8 Memory access

The VMIC 1 GE Fanuc VMIVME-5576 reflected memory interface allows data to be shared between up to 256 independent systems (nodes) at rates of up to 6.2 MB/s. Each reflective memory board can be configured with 256 KB to 1 MB of on-board SRAM. Local SRAM provided

Fast read access time to stored data. Writes are stored in the local SRAM and broadcast to other reflective memory nodes via high-speed fiber data paths. Data transfers between nodes are software-transparent, so there is no I/0 overhead. Send and receive FIFO in

Buffering data during peak data rates to optimize CPU and bus performance to maintain high data throughput.

Reflective memory also allows one or more nodes to be interrupted by writing to byte registers. These interrupt (level three, donkey definable) signals can be used to synchronize system processes, or to track any data that may precede them. Interrupts always follow the data to ensure that it is correct

Acknowledge interrupt before receiving data. VMIVME-5576 does not require initialization unless interrupts are used. If an interrupt is used, the vector and interrupt level must be written to the onboard register and the interrupt will be deployed.

Each node on the system has a unique identification number between 0 and 255. The node number is established by placing jumpers on the board during hardware system integration. Software can read the node number by accessing the onboard register. In some applications,

This node number is useful when establishing node functionality.
