Q: Can I get (read and write) the value of the attribute of the data acquisition parameter, for example, from the UI procedure?
Re: The main interface for sharing the values of the data acquisition parameters with the elements or attributes of the corresponding part of OpenSCADA is the static link that is fastest. However, the internal language and the dynamic object model of the nodes of OpenSCADA allow you to dynamically access the objects of the attributes of the data acquisition parameters, for example, you can get the value of the attribute by the function get().
