3. OPC Foundation established in 1996.
What is OPC ?
Object-oriented system provides standard framework for the configuration of reusable software components in Windows environment.
Industry standard OLE (COM) interface for data transfer between industrial clients and servers.
OPC Foundation established in 1996.
International Non-Profit Foundation established for enacting the specification of the OPC interface. (Membership of the OPC Foundation is now over 350)
Working as a member of committees for OPC specification.
Yokogawa has been a member of the OPC Foundation since it was established in 1996
OPC = OLE (Object Linking & Embedding) for Process Control
and
OPC = Openness, Productivity, Connectivity

Benefits of OPC
Reduced cost
Investment protection
Easier to maintain
Increased productivity
No single standard for interfacing with process data sources.
Application vendors must each develop proprietary interface.
Provides a standard interface for applications to communicate.
Vendors only need to adhere to the standard OPC interface.
