Product Overview
The Yokogawa VI451 Communication Module is a Vnet/IP to V net/VL net bus converter. It enables seamless communication between CENTUM VP Human Interface Stations (HISes) and CENTUM CS/CS 1000 systems. It serves as a core component in integrated process automation systems.
Key Applications
-
Facilitates integration / legacy CENTUM CS/CS 1000 systems into modern CENTUM VP environments
-
支持s distributed control in large-scale industrial plants
-
Ensures stable real-time communication over Vnet/IP and legacy networks
Product Advantages
-
Wide Compatibility: Connects multiple CENTUM generations (VP, CS 3000, CS 1000)
-
Redundancy Options: 支持s single or dual-redundant V net/VL net communication
-
Flexible Power: 可用 in AC and DC power supply variants
-
Robust Design: Rack-mountable with EMI shielding for industrial use
-
High Reliability: Suitable for mission-critical control environments
