Structured View objects

Structured View objects allow the operator view to be mapped to the objects present in a BACnet device, often using a data point addressing description.

With the exception of the top level (root level), all elements are connected to the respective parent object with the help of the iParent element.

The \/ (backslash and slash) characters can be used to create a text composition with the respective parent object.

For the properties Objectname, Description and EventMessageTextsConfig the separator is used, which is defined in the BACnet_Param of the library instance.

To use the function STRING_TO_UTF8 the library Tc2_Utilities must be integrated.
