Free OPC UA Modeler is a tool for designing OPC UA address spaces. It uses OPC UA specified XML format which allows the produced XML to be imported into any OPC UA SDK.

Basic features of the modeler work, but this is a work in progress.
Bug reports and feature requests are welcome.

Ïn the background the modeler uses an OPC UA server which can be connected to. The server is either a python-opcua server (default) or the C based open65421 server. To use the open62541 backend, open65241.so must be available as well as the its python wrapper.

Current state and plans can be found here: FreeOpcUa#3
