Practical Installation Case

A refinery upgraded its control system from CENTUM CS 3000 to CENTUM VP while retaining several legacy V net controllers. Engineers installed an AVR10D router between the Vnet/IP backbone and the existing V net domain. After configuring routing parameters and verifying redundant communication paths, operators successfully monitored and controlled both legacy and new controllers from a unified operator station without interrupting plant production.
