NON-EXCLUSIVE LICENSE AGREEMENT 
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.
