OPC UA (Open Platform Communications Unified Architecture) is an open communication standard for industrial communication that enables data and information to be exchanged between devices, machines and services. OPC UA supports digitalization and the requirements of Industrie 4.0 by providing a service-oriented architecture and semantic information modeling.
Connecting parameters to OPC UA means that the system's parameters can be represented as OPC UA variables or methods. These can then be read or written by other OPC UA clients to control or monitor the configuration or operation of the system. The Selmo standard supports OPC UA connectivity to higher-level or lower-level systems, such as ERP systems or sub-devices
