- Welcome to open62541's documentation!
- =====================================
- `OPC UA <http://en.wikipedia.org/wiki/OPC_Unified_Architecture>`_ (short for OPC
- Unified Architecture) is a protocol for industrial communication and has been
- standardized in the IEC62541. At its core, OPC UA defines a set of services to
- interact with a server-side object-oriented information model. Besides the
- service-calls initiated by the client, push-notification of remote events (such
- as data changes) can be negotiated with the server. The client/server
- interaction is mapped either to a binary encoding and TCP-based transmission or
- to SOAP-based webservices. As of late, OPC UA is marketed as the one standard
- for non-realtime industrial communication.
- We believe that it is best to understand OPC UA *from the inside out*, building
- upon conceptually simple first principles. After establishing a first
- understanding, we go on explaining how these principles are realized in detail.
- Examples are given based on the *open62541* implementation of the
- standard.
