Applications

The first element in the Device structure is the Applications container. It is a non-removable element, which offers a space to create user applications. It has one read-only slot:

• Number of Components: shows a sum of components used in all Application components (the sum does not include the Application components themselves).

The Applications container allows to add multiple Application components for building independent user applications, which are cycle driven and may work simultaneously.

The user may define the application purpose (heating, lighting, etc.) and a cycle time of algorithms operation (cycles may differ between applications).

Tip

Multithreaded applications allow to differentiate cycles of applications (scan period) in order to adjust them according to a purpose of an application.

For example, a HVAC application may be set to 1000 ms scan period, and a Lights application to 200 ms scan period, as changes to lights operation have to be implemented immediately. Setting such scan periods would mean that the Lights application would be executed 5 times for each HVAC application cycle.

The user may create as many applications as needed—as long as the overall number of Data Points used within user applications does not exceed the device license.

Note: For top performance, it is recommended to use up to three different applications.

Reordering

Reordering of components changes the execution sequence of components in the application. Reordering components in the nano EDGE ENGINE devices works in the Applications container. The option is available in the context menu of the Application and Equipment/Folder components. After invoking the Reorder option from the context menu, the dialog window pops up. In the dialog window, all components added under the Application/Equipment component are listed.

To reorder components, drag and drop them to a required position. Confirm reordering with OK.

Applications Libraries

The nano EDGE ENGINE Applications libraries provide sets of components (service and basic) that allow to create HVAC applications. Libraries are grouped by specific functionalities, for example, by families of algorithms, etc. This section provides information about the nano EDGE ENGINE libraries designed for the Applications container, their functionalities and elements.
