IC697VRM015 Reflective Memory Module

IC697VRM015 Reflective Memory Module  

Product Details Introduction

IC697VRM015 is a high-speed reflective memory communication module in GE Fanuc 90-70 series PLC systems, mainly used for real-time data sharing between multiple controllers. It belongs to high-performance data synchronization modules and is commonly used in large distributed control systems.

1、 Module positioning

This module is not a regular program storage board, but a dedicated communication module used to build a "shared memory network".

Multiple PLC nodes installed with VRM015 can form a real-time data synchronization network through fiber optic connection.

2、 Core functions

Reflective memory mechanism

After any node writes data to the module memory, the data will be automatically synchronized to all nodes in the network, achieving real-time sharing.

High speed fiber optic communication

Adopting a fiber optic ring network structure, it has high transmission speed and extremely low latency, making it suitable for real-time control scenarios.

Interrupt trigger function

Support write triggered interrupt mechanism, suitable for event driven control systems.

Multi node support

It can form a distributed system structure with up to hundreds of nodes.

Independent shared memory space

The module comes with a built-in reflective memory capacity (usually 256KB) for cross controller data exchange.
