The OPC Foundation, a non-profit corporation (the "OPC Foundation"), has established a set of standard OLE/COM interface protocols intended to foster greater interoperability between automation/control applications, field systems/devices, and business/office applications in the process control industry.
The current OPC specifications, prototype software examples and related documentation (collectively, the "OPC Materials"), form a set of standard OLE/COM interface protocols based upon the functional requirements of Microsoft’s OLE/COM technology. Such technology defines standard objects, methods, and properties for servers of real-time information like distributed process systems, programmable logic controllers, smart field devices and analyzers in order to communicate the information that such servers contain to standard OLE/COM compliant technologies enabled devices (e.g., servers, applications, etc.).
The OPC Foundation will grant to you (the "User"), whether an individual or legal entity, a license to use, and provide User with a copy of, the current version of the OPC Materials so long as User abides by the terms contained in this Non-Exclusive License Agreement ("Agreement"). If User does not agree to the terms and conditions contained in this Agreement, the OPC Materials may not be used, and all copies (in all formats) of such materials in User’s possession must either be destroyed or returned to the OPC Foundation. By using the OPC Materials, User (including any employees and agents of User) agrees to be bound by the terms of this Agreement.
