BACnet is a project designed to demonstrate how a device is connected via the BACnet communication driver. BACnet is not only used for defining communication services. Among other things, it is also used to define a number of objects and their properties through which data is presented. In this project, there are tags representing the properties of all Reliance-supported objects.

A device named BACnet1 is defined via the Device Manager. Within the device, several tags are defined and divided into folders based on individual BACnet objects. Each folder contains tags whose value allows you to read or write the properties of an object.

The type of object is specified by the Object type option, the property is specified by the Property identifier option. The Instance number option is used to distinguish the objects. The data type of a tag is changed automatically depending on the selected property. However, it can be changed subsequently. To test the example with a real BACnet device, it is necessary to configure these properties based on the real program of the device. Not all objects need to be used within the program and the Instance number option can differ for each object. Not all properties within BACnet objects are compulsory. Thus, some tags might not be updated successfully.

Upon project startup, the tray-type window on the left side contains several buttons used to switch between the windows defined within the project. Individual project windows contain displays and data grids showing objects' data based on tag data types.
