OPC Bridging Transfers Data between Industrial Automation Systems

Download Now


Integrators frequently use OPC technology to connect one Industrial Automation system (PLC, DCS, SCADA, HVAC, etc) with another so data can be shared between the two systems. Because OPC technology is based on the Client/Server architecture, the challenge is that two OPC Servers cannot communicate with each other directly. A variety of vendors provide an intermediate software solution, generically called an “OPC Bridge,” to facilitate this sort of communication. This whitepaper discusses the concept of the OPC Bridge, the solution architecture, required software components, and various features to help Integrators differentiate between different OPC Bridge products.
