MDIS history

Following the success of the SIIS JIP in developing a standard interface between the subsea control module (SCM) and subsea sensors, the concept of an MCS-DCS network originated, aimed at streamlining the Master Control System and Distributed Control System communications on topside systems through a collective effort between subsea controls vendors, topsides specialists and oil companies. The MDIS network was officially launched in February 2010 and aims to meet 4 times a year, alternating between the US and Europe. Meetings are held during the same week as SEAFOM and SIIS.

MDIS vision

''To optimize the MCS and DCS communications of topside systems (ref. ISO 13628-6), by developing a standard interface, in order to simplify implementation of data communication links, whilst increasing the data quality''


MDIS is open to organisations active in developing, interfacing with and deploying MCS and DCS data communication links.
