Welcome to ASMD Wiki

OPC Unified Architecture (UA) is the next generation of OPC. One of the most important improvements is a powerful Address Space and Information Model. OPC UA allows for the presentation of a real-time process and underlying infrastructure as a consistent information model built up with nodes. The process model is represented by nodes, attributes, and their mutual relationships. Therefore, this powerful concept allows us to present in UA not only raw process data but also complete information about the process state and process environment. The flexibility of UA ensures that no existing or future system is too complex to be exposed via UA. Of course, such flexibility leads to difficulties during configuration, that’s why Address Space Model Designer (OPC UA ASMD) has been born.

Concluding, Address Space Model Designer (ASMD) is a user-friendly tool supporting all aspects of the model designing process.
