Configuring BACnet Parameters
Using WCIS, do the following:
1. From the Device menu, select Device Properties to configure BACnet parameters.
2. In the Object section, enter information for the following fields:
– Instance Number – unique to BACnet network (valid values are 0 through
4,194,303).
– Object Name – unique to BACnet network (30 alphanumeric character limit in
RAD50).
– Device Description – description of controller (60 alphanumeric character limit).
– Device Location – physical location of controller (60 alphanumeric character
limit).
3. In the BACNet Communication Settings section:
– Set the CIS/MMI Command Priority to the desired value.
– Set Baud Rate to the MS/TP network baud rate. Options are; 9600, 19200,
38400 or 76800.
4. In the MSTP Slave section do one of the following:
– Check the MS/TP Slave check box if the controller is to function as a slave
device (when address range is 0 through 127).
– Set the Max Master Node number.
5.
In the
Device Settings
section (configuring the Room Unit port), do one of the
following:
– If using a sensing only Room Unit, the baud rate can be 1200 to 38400.
Use
38400
for optimal use with WCIS.
– If using a communicating digital Room Unit, the baud rate uses whatever
rate the network is using or sets it to 19200 after the controller address
is configured.
6.
In the
Device Settings
section:
– Set
MMI Baud Rate
to
38400
.
7.
Press the
Write
button. The controller accepts the configuration values and
then resets.
⇨ When the BACnet MS/TP TEC is successfully installed, the RX and TX
LEDs continuously flashes On/Off rapidly. This indicates a proper
communication with other devices on the network.
