OPC基金会致力于通过创建和维护开放规格来确保自动化的互操作性宣布MDI已选择OPC UA作为总控制系统（MCS）和分布式控制系统（DCS）协议标准。OPC UA的选择将为海上石油和天然气生产提供安全可靠的数据传输。
MDIS is an international joint industry network group whose main mission is to optimize the MCS and DCS interface of topside systems in oil and gas production. MDIS defines and establishes a standard for the interface, in order to simplify implementation of data communication links, whilst increasing the data quality. “In looking for the MDIS protocol, the network considered a number of potential candidates for validation testing. The MDIS community has selected the OPC UA protocol for further investigation due to its flexibility and performance over a broad number of criteria such as scalability, reliability, object orientation and the amount of anticipated time spent in programming / design,” states the MDIS steering committee.
“The OPC Foundation is excited to collaborate with MDIS in providing the MCS-DCS interface standard,” said Tom Burke, OPC Foundation President and Executive Director. "OPC UA will allow secure and reliable information exchange for the topside systems within offshore production.”
