Managing Device Units On The Controller Units Screen - Trane BACnet BCI-R Integration Manual

Configuring the BCI-R

Managing Device Units on the Controller Units Screen

The BCI-R device units can be viewed and managed on the Controller Units screen from either the
BACnet Setup Tool or Tracer TU.
When the BCI-R first powers up, or after the controller has been cleared, a list of points (the role
document) is created from the information supplied to the BCI-R from the ReliaTel RTRM module
through the Modbus link.
Note: The BCI-R creates the role document immediately (often within one second).
Immediately after the points are created, the device units are set and saved and appear on the
Controller Units screen. The values that correspond to the device units are set to default to SI
values. In some cases, the Custom radio button may be selected; however, the device units will still
default to SI.
If you are using Tracer TU to change the Device Units to IP by clearing the controller, it is best to
either unplug the Modbus cable to the BCI-R, or to power down the entire unit (the BCI-R). By doing
this, the BCI-R will not see Modbus traffic. This method will enable the Device Units radio button
selection, which allows you to make changes.
