Yokogawa AIP503 V-NET Coupler Module

The Yokogawa AIP503 is a V-NET Coupler Module used in the CENTUM CS 3000/VP DCS (Distributed Control System) architecture. As a vital part of the field control subsystem, the AIP503 enables high-speed, reliable communication between Field Control Stations (FCS) and other system components via the V-Net (Vertical Net) network. V-NET is Yokogawa’s proprietary control network designed for robust, deterministic, and fault-tolerant communication in industrial automation.

The AIP503 is specifically engineered to enhance data integrity, ensure redundancy, and maintain time synchronization across system nodes. Installed in a Node Interface Unit (NIU) or FCS module rack, this coupler ensures that large volumes of process data are transmitted with minimum delay, enabling real-time control in mission-critical environments like oil & gas, chemical processing, and power generation.
