MDIS Announcement 8th December 2021

The OPC Foundation Takes Ownership of the MDIS Sub-Sea Standard

The OPC Foundation (OPCF) is proud to announce that it consolidated and taken over the MCS-DCS Interface Standardisation (MDIS) specification ownership.  Effective immediately, as with all OPCF Companion Specifications, MDIS is freely available for adoption by all interested parties at no additional cost. The OPCF MDIS working group, co-chaired by Markus Koenig from SubSea, Tim Fortin from Honeywell, and Paul Hunkar from DS Interoperability, now oversees the ongoing maintenance and expansion of the standard. Original MDIS network group members will continue working in the OPCF working group. The OPC Foundation invites all members interested in helping shape the future of the MDIS specification to join the MDIS working group.
