    BACnet defines the direction of data flow from the point of view of the application running on the L-VIS device. An analog input object therefore accepts input from the user and transmits this data out to other devices on the network. An analog output object receives data from the network and outputs it to the application (show data on the display).

    Once opened, the contents of the file will be parsed and suitable data object templates will be created in the file import folder.
