BACnet Properties Configuration
To establish communication on the network, and guarantee a unique ID of devices in a BACnet system, the following
properties may have to be configured.
Table 1 - BACnet Properties Configuration
Property
Default Value
Configuration
MAC Address
001
•
Set to a unique address on the network between 000 and 254.
•
The value can be set manually via the menu.
•
The values from 128-254 represent MS/TP non-token passing slave
devices.
Device Instance
Auto
•
The humidifier automatically configures its device instance to 153,000 +
MAC address.
•
The value can be set manually via the menu.
•
The value can be set manually through the
WriteProperty
service to
Device Object.Object_Identifier
.
•
The device’s
Object_Identifier
is a combination of the
Device
Object_Type
(8) and the
Device_Instance
(0-4194302), therefore its
decimal or hexadecimal representation tends to be incomprehensible.
•
For example, the
Device_Instance
=1000 has an equivalent
Object_Identifier
of 0x020003E8 hexadecimal or 33555432 decimal.
Baud Rate
0 = Auto
•
The humidifier configures its baud rate automatically by detecting the
network upon connection.
•
The value can be set manually from the available values of (0) Auto, 9600,
19200, 38400, and 76800.
Max_Master
127
•
Configure
Max_Master
value to increase network efficiency when there are
less than 127 devices on the network.
•
The
Max_Master
value can be changed through the
WriteProperty
service
to
Device
Object.Max_Master
.
For more information, refer to the
section.
Device Object.Object_Name
Name of the
device
•
Configure the name of the device through the
WriteProperty
service to
Device Object.Object_Name
. For example, SKG4.
