TRANE TSCB0A Summit Communications Bridge Tracer Owner’s Manual
Bridging the communications gap
Introduction
Building automation systems play a crucial role in providing comfort,
security, and safety in today’s sophisticated building environments.
These intelligent systems use devices to control and monitor diverse areas, such as heating, ventilating, and airconditioning (HVAC), lighting, security, and fire- and life-safety systems. Communication between these systems enables information sharing, which optimizes and simplifies building control and monitoring.
In order for communication to occur, intelligent devices need to share a common protocol (language). The building control unit (BCU) of a Tracer Summit building automation system has the native capability to communicate with devices that use both BACnet and LonTalk protocols. With BACnet at the system level and LonTalk at the equipment level, Trane has the flexibility to communicate with dozens of suppliers to provide open system solutions (Figure 2).
However, many devices do not use either of these protocols. Trane’s Tracer
Summit communications bridge solves this problem by integrating devices that
use other protocols into the Tracer Summit building automation system,
effectively bridging the communications gap. Using the communications bridge
can help to reduce the cost and complexity of developing, integrating, and
supervising building systems and equipment.
The MODBUS protocol
The MODBUS protocol is an open, published protocol that is widely implemented
among control devices in HVAC industrial applications. Equipment such as
variable frequency drives, fume hood controllers, power monitoring systems,
and many more communicate using MODBUS. The Tracer Summit communications
bridge enables this wide variety of devices that use the MODBUS protocol to
connect to a Tracer Summit building automation system. The standard bridge
configuration is equipped with the MODBUS Remote Terminal Unit (RTU) protocol
and an Ethernet or Internet Protocol (IP) BACnet driver.
Configuration software and complete programming and installation instructions are also provided.
Product features
Compact size
The compact, four-inch-square size of the bridge frees up desk space and
provides mounting flexibility. This unit packs a lot of performance into a
small package.
Easy installation
The Tracer Summit communications bridge ships with all necessary cables and
adapters to make installation quick and easy. Because the 24 Vac power
requirement is readily available in most applications, the device can be
installed virtually anywhere in the building. Several mounting options are
supported, including the standard wall mount brackets or an alternative
Deutsche Industrie Norm (DIN) rail option for enclosure mounting.
Support for other protocols and drivers
In addition to the MODBUS RTU protocol, the communications bridge can also
support other common protocols and custom drivers from many different vendors,
including (but not limited to) the following:
- Allen Bradley
- Bell & Gosset
- Square D
- Liebert
- Notifier
LED status indicators
To make daily operations easier and more intuitive, the Tracer Summit
communications bridge incorporates LED indicators to display the status of the
following parameters:
- Power
- Ethernet communications
- Serial port communication
- Network communications
Alarm management
Receiving critical alarm data is crucial to maintaining a secure and
comfortable building environment. The bridge supports the transmission of
alarms to a Tracer Summit workstation or BCU. This standard application
eliminates the need to create custom software routines, which leads to lower
setup costs and more consistent, reliable operation.
Centralized scheduling and trending
All equipment connected to the Tracer Summit system using the bridge can be
scheduled from the central workstation for optimal operation. Additionally,
this data can be included in Tracer Summit system reports and trend logs.
