Welcome to MDIS

To streamline the Master Control System (MCS) and Distributed Control System (DCS) communications on topside systems, a standard interface using OPC UA was developed, including a standard communication protocol and information model. The MCS-DCS Interface Standardisation (MDIS) network was formed with involvement from key industry players in the subsea controls area, topsides specialists and oil companies. Standardisation of the interface simplifies implementation of data communication links, reduces testing and increases the data quality. Using the network group as a collaborative resource to the industry, it is able to facilitate information exchange in furthering development of the standard MCS-DCS interface.
