Introduction to BAScontrol20 Video Updated

BASroutersAugust 2015 - The BAScontrol20 Series - Introduction to the BAScontrol20 video has been updated to reflect the changes in the BAScontrol20 with the release of firmware 3.1. The video is an excellent resource for anyone wanting to learn more about the Sedona Open Unitary Controller.

Built on the Sedona Framework, Contemporary Controls has developed more than 100 custom Sedona components which complement the standard Tridium-developed Sedona 1.2 components that reside within the device. Unique to the BAScontrol20 are 48 Web Components that allow wire sheet data to be read and written from a common web browser. With firmware 3.1, virtual points - which allow wire sheet data to be read and written from a BACnet client - have been expanded to 24.

The BAScontrol20, 20-point BACnet/IP Sedona Open Unitary Controller supports both BACnet/IP and Sedona Framework (SOX) protocols via an Ethernet connection. It complies with the BACnet B-ASC device profile having eight universal inputs, four binary inputs, four analog outputs and four binary outputs (relay or triac). The device is a freely-programmable controller executing Sedona's drag-and-drop methodology of assembling components onto a wire sheet to create applications. It can be programmed using Niagara Workbench or a third-party Sedona programming tool; or configured for BACnet/IP remote I/O applications using a common web browser. A free Sedona Project Backup and Restore utility called BASbackup is available for saving all project data including program, configuration and web page data.

There are no hardware changes on the BAScontrol20 and it is possible to re-flash existing controllers in the field by first contacting Contemporary Controls' technical support. The following is a list of new features found in firmware version 3.1.

  • Virtual points increased from 8 to 24 points - Sedona and BACnet readable and writable
  • Universal Input options expanded - 20kΩ thermistor, and a 1-100kΩ resistance range
  • CControls Function Kit added - 16 new components including Psychrometric (SI/English)
  • Additional Change-of-Value (COV) subscriptions - 14 binary and 2 analog in total
  • Increased performance and larger application memory space - supports larger app.sab
  • More informative web pages - all points identified by BACnet name and color-coded by function
  • Network Time Server can be found by domain name - easy access to pooled NTP servers
  • Improved Universal Counter (UC) component - mimics Sedona counter but with persistent memory
  • The BASbackup Sedona Project utility easier to use - not dependent upon the Workbench tool
