Advantages of BASautomation Products to be Displayed at China Refrigeration Expo

March 2015 - Contemporary Controls (Suzhou) will be attending the China Refrigeration (CRH) Expo from April 8-10, 2015 at the Shanghai New International Expo Centre, China. The CRH Expo is a large, international platform where the latest technologies, products and services in the HVAC&R industry are showcased. Over 40,000 people attended last year.

Make sure to stop by Contemporary Controls' Booth W5A13 to see our cost-effective, BAS products designed to accompany HVAC&R automation networks from our BASautomation® - Building on BACnet® product line.

BACnet BASrouters
Our economical, standalone BASrouters provide routing between networks such as BACnet/IP, BACnet Ethernet and BACnet MS/TP. The BASrouterLX high performance router has a high-speed processor attached to a BACnet client via a 10/100 Mbps Ethernet network, and can support serial data rates up to 115.2 kbaud.

• Captures MS/TP traffic for viewing by a Wireshark network analyzer
• Advanced features include MS/TP slave proxy support (allowing auto-discovery of MS/TP slaves) and MS/TP frame capture and storage for use with Wireshark®
• As a BBMD, up to 50 BDT and 147 FDR entries can be supported
• Two physical communication ports - a 10/100 Mbps BACnet/IP Ethernet port and an optically-isolated EIA-485 port for MS/TP
• Router configuration is accomplished via web pages
• DIN-rail mounting

BACnet / IP Controller
The BAScontrol20 utilizes a powerful 32-bit ARM7 processor with 512 kB of flash memory plus a 16 Mbit serial flash file system for storing configuration data and an application program. By operating at the BACnet/IP level, the BAScontrol20 can share the same Ethernet network with supervisory controllers and operator workstations.

• Can be configured for a fixed IP address or can operate as a DHCP client receiving its IP address from a DHCP server
• BACnet/IP compliant with a B-ASC device profile
• Eight universal inputs, four binary inputs, four analog outputs, four binary outputs
• Real-time clock with super-cap backup that allows for creating local schedules
• Provides 66 Sedona components from Tridium, and 100 custom components from Contemporary Controls. (These include 48 web components that can be viewed and manipulated by a web browser and 24 virtual points that can be read or written by a BACnet client).

Powered by Sedona Framework™
In addition to its 20-points, the BACnet/IP Sedona Field Controller incorporates Sedona Virtual Machine (SVM) technology. System integrators using the device can develop control applications with Workbench's powerful drag-and-drop visual programming methodology and tools such as Niagara Workbench or Sedona Workbench. Once developed, the program remains stored in the BAScontrol20 and executes by way of the SVM. The application can run standalone or interact with a program in a JACE supervisory controller over Ethernet. The amount of potential applications is unlimited. Models exist for both triac and relay binary outputs.

Web-based Graphical Interface
The BASview is a stand-alone, embedded, web-based graphical interface for building automation and process automation systems. It can be accessed from any web browser - providing client functionality to any BACnet/IP or Modbus TCP system and it requires no licensing. By using Contemporary Controls BASrouter or BASgateway products, additional protocols such as BACnet MS/TP and Modbus RTU and Modbus ASCII are supported.

• Easy to install and use.
• Client features include animated graphic screens, scheduling, historical trending, runtime accumulation and alarm monitoring.
• Automatically toggles outputs and changes setpoints on schedule, collects runtime and trend data, and monitors alarm conditions.
• As an embedded device, BASview uses Flash memory for internal storage instead of a hard disk to maintain its ruggedness.

The BASview is totally self-contained, requiring no external PC or application for its use. Any number of web browser users can access the device. The only requirement is the installation of an Adobe Flash player in the browser.

BACnet Gateways
For those who need to integrate BACnet systems with Modbus devices such as those used for boiler control, variable speed drives, and metering applications, our cost-effective BASgatewayLX is designed to make gateway commissioning as simple as possible.

• With virtual routing, up to 30 Modbus devices appear as individual BACnet devices.
• Using web pages and a resident database of common Modbus device profiles, Modbus registers can be mapped to BACnet objects.
• Comprehensive library of Modbus device profiles reside within the BASgatewayLX that helps to remove the burden from the system integrator commissioning the system.
• Additional custom device profiles can be downloaded from our website.
