Understanding OPC UA Read and Subscription Behavior
Free App Notes
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. OPC UA is the latest standard with adoption increasing each year due to the remote connectivity benefits it provides over OPC Classic.
