OPC UA Client

OPC UA (OPC Unified Architecture) is a protocol for industrial communication and has been standardized in the IEC62541. 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 to a binary encoding and TCP-based transmission.

OPC UA function block API

Our function block library for an OPC UA client application is based on the API of the project . Supported are currently the data exchange with Integer, Float and Array variables. The server part is still under development.


OPC UA implementation of the open62541 project now ported for cross compiling for QNX 7.0 x86_64 under Linux. Contact:
