Sedona Helping Create a Truly Open Controller

Developed by Tridium, Inc, Sedona is an open-source software environment designed to make it easy to build smart, networked, embedded devices which are well suited for implementing control applications. The Sedona language facilitates component-oriented programming where components are assembled onto a wire sheet, configured and interconnected, to create applications. Sedona was made available to the public under an Academic Free License (AFL 3.0) granted by the licensor—Tridium, Inc. A licensee was allowed worldwide, royalty-free and non-exclusive use of the technology.

Using Niagara Workbench or a Sedona tool, such as Contemporary Controls' Sedona Application Editor, components are assembled onto a wire sheet, configured and then interconnected with other components to create applications. Program changes are immediately executed. This language is ideally suited for graphical representation of control strategies. It has a similar look-and-feel to the popular Niagara Framework™ and it is IP-based. Those with experience with Niagara Framework will have no problem understanding Sedona. For those without Niagara experience, the graphical representation of components linked on a wire sheet to create applications is intuitive and can be easily learned with a minimum of training.

Contemporary Controls has produced several controller products in its BAScontrol series that use Sedona. In addition to developing custom Sedona components, Contemporary Controls has developed a Java-based Sedona tool called Sedona Application Editor (SAE) for those individuals who do not have access to Niagara Workbench and need to program Sedona devices. BASbackup, a BAScontrol Project utility is available that not only archives Sedona application programs but controller configurations as well thereby creating a complete project backup. The Sedona technology is portable to other platforms and to prove it Contemporary Controls has developed the BASemulator that mimics a real controller on a Windows PC. The BASemulator, SAE and BASbackup comprise the BAScontrol Toolset which is available for free after registering with Contemporary Controls.
