B.6.3 BACnet Target Devices
One or more slave devices are added to the BACnet PTP interface node
in the network pane of XBuilder, as shown for the Panel device of the
SrlSim example network in the following screenshot.
Device Template
Device templates having a [BACnet] filename prefix are used to create
BACnet PTP network devices in XBuilder. Subsequently, each device
node is used to configure communications with the physical slave it rep-
resents on the target network.
Device Properties
• Address – Allows the required device address to be entered. The
entered number should correspond to the unique address of a
device on the target network (1 to 255).
Device Status Signal
For each device the BACnet PTP driver generates a communication sta-
tus signal.
• online – Flags ONLINE during normal device communications,
and will change to OFFLINE if communications with the target
device have failed. An OFFLINE condition normally indicates an
incorrect device address having been entered, or by incorrect wir-
ing of the network connection to it.
Notes
• Target devices must all be connected to a single BACnet net-
work. This network should normally be the one directly con-
nected to target half-router, as this minimizes the network traffic
that must be routed to a remote BACnet network.
• The same device address can be used for multiple devices to
allow splitting of a large set of I/O values into smaller pseudo
“device types”. This can be useful for target devices that contain
several logical data value groups because each group can appear
as a separate node in XBuilder.
