The most popular OPC Specification today is OPC Data Access (DA). OPC HDA is a distant second, while OPC Alarms & Events (A&E) is a very distant third. Nevertheless, as more users demand standardized access to their historical process data, OPC HDA continues to gain ground. Already all the major historian vendors support OPC HDA.
