Configuring BACnet Parameters

NOTE:

WCIS version 3.0 or later must be used to configure Siemens Building

Technologies BACnet MS/TP Equipment Controllers.

Do not check the Metric checkbox in the Device Properties dialogue box if the

controller is communicating through the MS/TP driver in the field panel. Metric

can be checked only if the controller is communicating through a router. If you

need metric and the controller is communicating through the MS/TP driver in the

field panel, then the Metric checkbox in the Device Properties dialogue box must

be unchecked and the conversion must be handled in the field panel.

Using WCIS, do the following:

1. From the Device menu, select Device Properties to configure BACnet parameters.

− Object Name – unique to BACnet network, (12 character RAD50 limit).

− Object ID – unique to BACnet network, valid values are 0 through 4,194,303.

− Description – description of controller (60 character limit).

− Location – physical location of controller (60 character limit).

− MSTP Network Baud Rate – options; 9600, 19200, 38400 or 76800, default

is19200.

2. Configuring the Room Unit port.

− If using a sensing only Room Unit, the baud rate can be 1200 to 76800. For

optimal use with WCIS use 38400.

− If using a communicating Room Unit, the baud rate must be set to 1200.

3. 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 flash

On/Off rapidly and continuously.

The startup is complete upon completion of BACnet parameters configuration.
