Introduction

MDIS.JPGThe MDIS (Master Control Station (MCS) - Distributed Control System (DCS) Interface Standardisation) is an international joint oil and gas industry network group.

MDIS was formed with a vision to optimize the MCS and DCS communications of platform topside systems, by defining and establishing a standard for the interface, in order to simplify implementation of data communication links, whilst increasing the data quality. By implementing the MDIS standard the operator should benefit from simplified implementation and testing of the MCS - DCS interface, reduced risk of interface failures and reliable control and monitoring via the DCS. It includes oil and gas operators, DCS vendors and Subsea vendors.
Platform


MDIS selected OPC UA based on several requirements:

  • Information modeling capabilities
  • Multi-platform support
  • Redundancy and Robust Communications
  • Independent Organization Support
  • Independent Testing and Certification

The MDIS companion standard includes information models to represent the common pieces of subsea equipment, such as valves, choke valves, instruments and discrete IO to name a few. The companion specification includes support for two different architectures. It also defines interface an information model specific testing.
