5LEDs

Purpose 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, while 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” on page 3-14.

Dialog Box The ActiveX Control Properties dialog box governs the appearance and

functionality of the ActiveX control itself. The table below lists the panels of the

ActiveX Control Properties dialog box.

The

Block Parameters dialog box governs the interaction between Simulink

and the ActiveX control embedded in the block. See “Summary of Dialog Box

Fields and Check Boxes” on page 3-29 for details.
