Chapter 6 UCMs supported by Tracer Summit systems
62 BMTX-SVN01C-EN
GLDs: Generic LonTalk
®
Device
LonTalk
®
devices support LonTalk protocol but do not meet the Lon-
Mark
™ profiles that Tracer Summit software supports, such as SCC or
DAC. However, LonTalk
®
devices can be connected to Tracer Summit as
Generic LonTalk
®
Device (GLD) objects. GLDs must support LonMark
standard network variable types (SNVTs). The BCU integrates these
devices into Tracer Summit by mapping SNVTs to standard BACnet
objects (AIP, AOP, BIP, BOP). These BACnet objects can then be used in
various Tracer Summit applications, such as TOD scheduling, graphics,
and CPL programs.
The BCU gets the information it needs for mapping SNVTs to standard
BACnet objects from an external interface file (XIF). You will need to
transfer this information to the Tracer Summit PC Workstation. The XIF
file is supplied by the manufacturer of the generic LonTalk
®
device.
Generic LonTalk
®
devices include: variable frequency drives (VFDs),
meters, occupancy sensors, actuators, and I/O modules. Typically, these
devices will be pre-configured by the original equipment manufacturer.
They communicate using the Comm5 communication link.
For detailed information about generic LonTalk
®
devices and how they
operate in Tracer Summit, refer to Tracer Summit Connections to Non-
Trane LonTalk
®
Devices (BAS-PRB003-EN).
Horizon absorption chiller interface
Tracer Summit can monitor, control, and configure Horizon absorption
chillers. The Horizon interface provides a Comm4 communication link
between each Horizon absorption chiller and the BCU. For specific infor-
mation about the number of Horizons allowed per BCU and per communi-
cation link, refer to Table 5 on page 33.
Absorption chillers manufactured in China and known by the names
Dragon and Navigator also are controlled and monitored using this inter-
face. This section refers only to the Horizon chillers, but applies to the
Dragon and Navigator chillers as well unless specifically stated.
You must configure the menu items on the UCM for proper Tracer Sum-
mit operation according to Table 11.
