dc.description.abstract	"OPC" is an important new specification designed to solve interoperability problems in the process control environment. It is based on Microsoft's Component Object Model (COM). The paper surveys and describes the OPC specification and discusses whether it satisfies the requirements for use in a real-time Distributed Control System (DCS). Some authors have criticised OPC because it is closely linked to Microsoft's Windows NT, which is not a true real-time operating system, and COM, which has no real-time support. This paper examines these criticisms, as well as the OPC Foundation's arguments for OPC, in the context of the requirements for a real-time control system.	en
