　　VMIVME-2170A Other names:

　　Reflective Memory Board VMIVME-2170A

　　VMIVME-2170A Main Control Board

　　Controller module VMIVME-2170A

　　Product Description

　　This module is one of the VMIC/GE Fanuc modules, designated as the VMIVME-2170A unit of this series. This board is designed as a reflective memory board that can transmit data. It achieves this by recording data onto onboard RAM. The reflective memory concept of these boards provides a very fast and effective way to share data between distributed computer systems. VMIVME-2170A Reflective Memory Board is a special type of industrial control module that integrates reflective memory technology, aiming to achieve efficient data sharing between multiple independent computers or devices. This technology saves independent backups of shared memory at each node in the network, enabling each node to access and modify data at extremely high speeds, thereby achieving low latency and high communication efficiency. This module not only supports high-speed data processing and response, but also has high reliability and flexibility, suitable for various real-time control and monitoring scenarios.

　　Technical characteristics

　　High speed data transmission: The VMIVME-2170A reflective memory board adopts advanced fiber optic technology and high-speed data processing capabilities, which can transmit data to every node in the network in microseconds, ensuring real-time and synchronization of data.

　　Global memory access: This technology allows all computers or devices connected to a reflective memory network to access shared memory simultaneously, without the need for complex network communication protocols, greatly improving the efficiency and convenience of data access.

　　Software Transparency: Reflective memory technology transparently monitors and replicates data, allowing applications to share data without software overhead, reducing system complexity and maintenance costs.

　　High reliability: The VMIVME-2170A reflective memory board has been carefully designed and rigorously tested, with high reliability and stability, and can adapt to various harsh industrial environments.

　　The VMIC/GE Fanuc series was developed by General Electric and produced by the company's industrial automation department, but these products were later acquired and developed by Abaco Systems.

　　The VMIVMVE-5576 interface module allows 256 independent systems to share data at a rate of up to 6.2 MB.

　　The reflective memory board in the VMIC/GE Fanuc series is designed to be configurable for data sharing and retention, with onboard SRAM up to 256 KB to 1 MB.

　　The reflective memory integrated in these VMIC/GE Fanuc models is programmed to interrupt multiple nodes simultaneously by sending it to a byte register. These signals synchronize system processes.

　　Node interrupts can follow data. This ensures that data reception is complete, and then enables interrupts after reception. The construction of the VMIVME-2170A unit eliminates the need for initialization before using the interrupt function.

　　Reflective memory function:

　　Reflective memory network is a special type of shared memory system designed to allow multiple independent computers to share a common dataset. VMIVME-2170A, as a reflective memory board, can save independent backups of the entire shared memory in each subsystem, achieving high-speed synchronization and sharing of data.

　　When data is written to the local reflection memory backup, high-speed logical synchronization transfers it to the next node in the ring network, ensuring that all nodes have the same data copy in a very short period of time.

　　Input and output capabilities:

　　VMIVME-2170A provides multiple input and output channels, which can process digital and analog signals. This enables it to receive input signals from external devices such as sensors and switches, and generate corresponding control signals to control external devices such as actuators and relays.

　　This module has fast data processing and response capabilities, suitable for industrial scenarios that require real-time control and monitoring.

　　Interface and compatibility:

　　VMIVME-2170A complies with the communication interface standards of industrial control systems, facilitating integration with other devices and systems. It can be physically installed or connected to various computer buses, including VME, PCI/PCI-X, CompactPCI, PCI Express, etc.

　　This broad compatibility enables VMIVME-2170A to be suitable for various industrial control systems and application environments.

　　Application scenarios

　　The VMIVME-2170A reflective memory board is widely used in industrial control systems that require low latency and high communication efficiency, including but not limited to:

　　Industrial automation: In factory automation systems, it is used to monitor and control various equipment and parameters in the production process.

　　Data acquisition and monitoring system: To achieve the collection, processing, and display of various parameters and signals, and improve the monitoring ability of the system.

　　Building automation: In building management systems, it is used to control and manage lighting, air conditioning, security and other equipment.

　　Transportation system: In intelligent transportation systems, it is used to achieve functions such as traffic signal control and vehicle detection, improving the efficiency and safety of the transportation system.

　　Precautions

　　Fiber optic connection: Due to the use of fiber optic technology in the VMIVME-2170A reflective memory board, it is necessary to ensure good fiber optic connection to avoid affecting data transmission speed and stability.

　　Driver and parameter settings: Proper installation of drivers and parameter settings are key to ensuring the proper functioning of the VMIVME-2170A reflective memory board.

　　Avoiding hardware conflicts: During use, it is important to avoid conflicts with other hardware to ensure system stability.

　　VMIVME-2170A Reflective Memory Board is a powerful and flexible industrial control module that provides efficient and reliable data exchange solutions for industrial control systems through its integrated reflective memory function and high-speed input and output capabilities. Whether in the fields of industrial automation, data collection and monitoring, building automation, or transportation systems, VMIVME-2170A can play its unique role in promoting the intelligent and efficient development of industrial control systems. It utilizes reflective memory technology to achieve high-speed data sharing and synchronization between multiple independent computers or devices, providing strong technical support for industrial automation, data collection and monitoring, building automation, and transportation systems.
