OPC Data Access
For most people, when they speak of OPC, they usually mean the OPC Data Access set of specifications.
The current OPC Data Access specification is version 3.0. However, there is currently very little software which implements Data Access 3.0. The vast bulk of software which uses OPC is designed around the Data Access 2.0 specification (actually version 2.05a).
These documents provide introductions to OPC Data Access:
OPC Unified Architecture
OPC Unified Architecture (UA) is the next generation of OPC. It brings the existing specification domains together with a single coherent data model and uses web services, rather than Microsoft COM, for messaging.
See our OPC UA page for more information.
The OPC Foundation newsletter, OPConnect, carries features on current OPC initiatives.
All OPC specifications may be obtained from OPC Foundation's Downloads page.
