OPC Server
OPC Server
The value of OPC is that it is an open standard, which means lower costs for manufacturers and more options for users. Hardware manufacturers need only provide a single OPC server for their devices to communicate with any OPC client.
Software vendors simply include OPC client capabilities in their products and they become instantly compatible with thousands of hardware devices. Users can choose any OPC client software they need.
Two OPC DataHubs can mirror data across a TCP network to provide OPC tunnelling. Resting assured that it will communicate seamlessly with their OPC-enabled hardware, and vice-versa.
Third Party Communication between automation devices : OPC Server
The OPC DataHub is uniquely designed to do all of these tasks. It is a combination OPC server and OPC client that supports multiple connections. Thus it can connect to several OPC servers simultaneously, for OPC aggregation and OPC bridging.
OPC is the interoperability standard for the secure and reliable exchange of data in the industrial automation space and in other industries. It is platform independent and ensures the seamless flow of information among devices from multiple vendors. The OPC Foundation is responsible for the development and maintenance of this standard.
