To streamline the Master Control System (MCS) and Distributed Control System (DCS) communications on topside systems, a standard interface needs to be developed, including a standard communication protocol. The MCS-DCS Interface Standardisation (MDIS) network has 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, whilst increasing 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.
The first edition of the MDIS Standard was published in January 2017. The Standard is available via the OPC Foundation here.
