You want to modify the properties of a BACnet object.
From the system tree in the left pane, select an object.
In the Property Name column in the right pane, select a property name.
From the Services menu, click Write Property. NOTE: The Write Property function is grayed out if you're not allowed to edit the object property. In addition, the BACnet device may reject the attempted write. If so, an error displays in the bottom pane.
The Write Property dialog box displays.
Modify the fields in the Write Property dialog box.
Do one of the following:
Click Send Now if you have no other properties to edit.
Click Send Later if you have other properties to edit and want to send all the changes at one time. When you are finished editing the other properties, click Send Now.
The new value is written or commanded to the object, and the right pane of the BACnet Object Browser is updated.
