New BACnet/IP Sedona Field Controller Provides Ideal BAS Solution
February 2014 - Contemporary Controls' new BAScontrol20 is a cost-effective BACnet/IP controller that provides a useful mix of eight universal inputs, four binary inputs, four binary outputs and four analog outputs. Models exist for both triac and relay binary outputs. The device is ideal for unitary control or for expanding I/O points in the field via an Ethernet connection.
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. The unit can be configured for a fixed IP address or can operate as a DHCP client receiving its IP address from a DHCP server. A real-time clock with a super-cap backup allows for creating local schedules. The BAScontrol20 is ideally suited for structured wiring systems and is BACnet/IP compliant with a B-ASC device profile.
Powered by Sedona Framework®
With 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.
Tridium's Sedona 1.2 kits of components are included in the BAScontrol20 - as well as Contemporary Controls' product-specific kits. The BASC20 IO Kit components interface physical points to Sedona wire sheets and provide eight virtual points to a BACnet client and four retentive counters. For remote Ethernet I/O applications, the unit can be configured with minimal effort using a simple web browser.
With its 48 web components from its BASC20 Web Kit, the device allows the viewing or writing of Sedona wire sheet points using just a web browser. The BASC20 Web Kit shares data with onboard user-designed webpages. This allows data interaction with Sedona valuables without the need of a Workbench Tool. Input components receive data from hosted webpages. Output components send data to hosted webpages.
Convenient Web Pages
An overview of all real and virtual points is provided through the main web page. Points can be temporarily written by entering a value into one of the points. The main webpage provides viewing of all webpages and the separate web pages allow the configuration of up to 48 web components. Web components provide a means to write and read data to and from Sedona wire sheets without the need of a Workbench tool. A web component configured as a wire sheet input can have its input range restricted to minimum and maximum values - eliminating the need to add limit detection within the wire sheet logic.
