OPC is the standard of choice for interoperability between software and hardware in the multi-vendor real world. That success has resulted in greater availability of data and has generated greater demand for access to the data across a wider number of locations and users. However, when OPC clients and servers are on different computers, or at remote locations, making a secure, reliable and resilient connection has its challenges and risks.
In this whitepaper, you will learn more about the challenges in multi-computer, networked, and multi-site data integration architectures using OPC, including how OPC clients and servers connect, the role of a technology called DCOM, and how you can overcome them using a technology known as tunneling.
