Controls

7-segment display

A control in Design view used to display static or live values. It receives its value in Logic view via a connection to a data source, for example by selecting the single-value view of the visual energy database values or a live value.

DB Navigator

This is the control used to select time ranges. It can make its navigation data available to all data controls on the output side. The navigation data can be used in Design view to allow the dashboard user to switch flexibly between different time ranges. The navigator can also be set to a fixed time range as the initial value.

Data table

A graphical control for displaying database values in tabular form. A data table is the simplest way to display multiple database values in one place, without having to create various labels, links or charts. Another advantage is the automatically adjustable column total.

Live value

Logical control – This control enables live values to be passed to charts or other controls in the dashboard. Use the “Source” tab to select the data point to be passed on.

Database values

Logical control – This control enables database values from visual energy to be passed on, for example, to a chart. Depending on the settings, only the total, average, maximum or minimum values may be output. In addition, the time range can be defined directly on the control or passed via the DB Navigator.

Comparator

Logical control – This control in the Logic view allows two numerical values to be compared. Depending on the result of the comparison, a label or display, for example, can be set to “visible” to show a note or a warning. The three (comparison) outputs (1>2, 1<2, 1=2) send a logical value. The outputs (Vout1, Vout2) provide the value of the respective input of the same name. For Vin2, a constant value can also be entered in the V2Const parameter. However, as soon as an input value is received at input Vin2, the constant value is ignored.

Calculator

Logical control – This control in the Logic view is used to link up to 10 data points or input fields. It calculates up to 4 values from a maximum of 10 numerical input values. Any JavaScript expression can be entered into each of the four formulas. To use the input values in the formulas, you must use a # character followed by the input number as a placeholder.

Example: To perform the following calculation, “((Value1 + Value2) * 1000 / Value3)”, you must enter the following formula: (((#1 + #2) * 1000 / #3).

Until an input value is received, the value 0 is assumed. If the formula is invalid or an exception occurs, NaN is output.
