LEDs (Dials & Gauges Blockset)

Display input value using one or more two-state graphical elements

Description

Blocks in the LEDs library use graphical elements to imitate light-emitting diodes (LEDs). Each block reflects its input value by setting one or more graphical elements to an on or off state. By default, the number of LEDs in the on state is the rounded value of the block's input. If the rounded value is nonpositive, then all LEDs are in the off state. If the rounded value exceeds the number of LEDs, then all LEDs are in the on state. To learn how to use and customize blocks in this library, see LEDs.

Blocks in the Library

Dialog Box

The ActiveX Control Properties dialog box governs the appearance and functionality of the ActiveX control that is embedded in the block. The table below lists the panels of the ActiveX Control Properties dialog box.

Panel
Purpose

Background
Configure the background and outline of the block

LEDs/General
Define the number, arrangement, and behavior of LEDs on the block

Library
Refer to property settings as a named collection

Style
Define the appearance of LED graphical elements (The LEDs/General panel uses the LEDStyleID property to reference the styles defined here.)
