BACnet MS/TP Client
BACnet MS/TP Client can be configured on the RS-485 port of the gateway by
selecting
BACnet MS/TP Client
from the protocol dropdown menu. The gateway
can read and write the present value property of BACnet objects hosted by other
devices on the network. This behavior is defined by configuring BACnet service
objects. For more information on service objects, refer to section 8.5. Whenever
the BACnet MS/TP client driver is enabled, the BACnet device object is always
present and must be properly configured. This section will discuss how to
configure the BACnet MS/TP client.
