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.
