OPC Tunnelling: Increases Data Availability for OPC DA, HDA and A&E


OPC is the current de facto open communication standard in the world of industrial connectivity. It offers improved data connectivity, while lowering the cost of data transfer between devices and applications. The most widely used OPC specifications employ communications layered on top of various Microsoft operating system components. These components function very well under office-like LAN conditions, but under less favorable conditions, their behavior often leads to unreliable data delivery, and even data loss. Download this white paper to learn how OPC Tunnelling technology provides a solution to this problem.
