Outline

G-Link is a communication system designed to ensure real-time information collection and remote control by connecting field units built into actuators in a loop using either optical or metal cables.

The master station can be connected to the host computer (such as a DCS) through:
– Di/Do signals
– Ao outputs of valve opening
– Communication (Modbus protocol)

This system is ideal for the centralized control of plants.

Features

– Actuators are connected in a loop using optical or metal cables for remote monitoring and control.
– Up to 127 field devices can be controlled with a single loop.
– Supports multiple functions, including:
• Opening position display
• Status monitoring
• Warning and alarm transmission
– Flexible host computer interface: RS-232 (Modbus), Di/Do, Ai/Ao

Benefits

– Simplifies plant-wide centralized control.
– Enhances reliability with loop communication structure.
– Provides real-time monitoring for safer and more efficient plant operation.
