6.3 Creating an Application Program
Using the workbench tool, the systems integrator drags and drops components from
the various available kits found under the Sedona Palette onto a wire sheet. These
components are then linked together using “wires” to depict control flow from
sensors, to control logic and then to actuators. Most of the control logic components
come from the Tridium kits while input/output components are from the BASC20 kits.
Some components can be configured and all must be identified with a unique
reference name or by accepting the default name. The integrator’s role is much
easier than that of the developer in that he is graphically building an application on a
live target using a building-block approach without any concern about how the kits
were developed. He can make changes as he tests his logic until he is satisfied with
the result. However, his job is not complete until he saves his work because these
changes will not be retained if power is lost to the Sedona Device. Once the control
scheme is developed and tested on the BASC20 itself, an app.sab file is
automatically saved to flash memory in the Sedona Device for execution by the
device’s SVM after the user right clicks app and selects Action->Save in Workbench.
At this point the application program is properly retained in the Sedona Device and a
backup copy can be saved in the workbench tool using the Get utility.
