Using Tridium s Sedona 1.2 Components with Workbench

Transcription

1 Using Tridium s Sedona 1.2 Components with Workbench This tutorial assists in the understanding of the Sedona components provided in Tridium s Sedona release. New with the 1.2 release is that the Sedona components, previously concentrated in one Control kit, are now organized in smaller kits under a functional name. Components discussed in this document can be found in the following kits: basicschedule datetimestd func hvac logic math pricomp timing types Sedona components are deployed in kits of which there are three types Tridium-release, custom hardwareindependent, and custom hardware-dependent. This tutorial only addresses the Tridium-release components which can be found in any Sedona application. By Tridium-release we are referring to Tridium release Custom components deployed in custom kits are provided by developers from the Sedona community. It is up to the developer to explain how their custom components function. They are not explained here. However, the techniques found in this tutorial can be applied to any Sedona project. The intent of this tutorial is not to teach how to create HVAC applications using Sedona because Sedona can be used anywhere where control of processes is required. It is only intended to introduce the basic Sedona components which can be assembled onto a wire sheet by integrators thereby creating applications. This tutorial was conducted using Niagara Workbench as the Sedona tool so the appearance of the components and the configuration of parameters are unique to this tool. Other Sedona tools such as the Sedona Application Editor create a somewhat different appearance of the components and use different methods for configuration. However, all the examples in the tutorial can be implemented with any Sedona tool.

2 Variable Types Although there are several variable types used by Sedona, three are the most interesting Boolean, Float and Integer. You can define constants for each type and use converting components to change the data representation to a different type. Configuring Constants Contemporary Controls Page 2 February 2017
