device_object_name is programmed on the
LUI and defaults to "VA301C:1" and X is
relay number (1 to 4). Thus the default
object_name for Relay #4 will be
"VA301C:1.rel4"

True state of the relays. These take the
value of the highest-priority BACnet
command. If no BACnet command, this
takes the value of the associated event.
