Understanding OPC: Open Connectivity via Open Standards

By Tony Paine, Kepware Platform President

This eBook explores how the "Device Driver Problem" occurring in the mid-1990s lead to the establishment of the OPC Foundation and the development of OPC specifications. It provides a foundation of knowledge on OPC DA (a "classic" standard) and examines other OPC specifications (paying particular attention to Alarms & Events [AE], Historical Data Access [HDA], and Unified Architecture [UA]).
