Disable module (attribute node) in LabVIEW

Preface

Labview We often use attribute nodes in , What are the attribute node modules ？ Next, I will introduce the options in the attribute node one by one . In this article, we mainly talk about disabling .

One 、 The open position of the attribute node

1. Attribute nodes need to rely on data . For example, data types , The attribute node can be opened for all waveforms .

The above figure shows the controls that can use the attribute node function .（ It's just part of it , Not all ）

How to open the attribute node ？

We found that there are many modules in the attribute node , Next, I will explain the commonly used functions .

Two 、 Disabled use

  Indicates whether the user can operate the control .


First in their own LabView Open the disable tab for a Boolean quantity ;

Get a control as shown in the figure below , That is to say == Ban （Disabled）==

The function of this attribute is similar to advanced in the shortcut menu of the front panel control » Enable status items , And the enable status option of the external view page in the properties dialog box .== Generally speaking, it is to control whether this control is available through the connection port ！==  The disabled input port can be connected in tab form , It can also be controlled digitally .

The following figure shows tab control ：

The tab opens as shown below ：

You need to right-click the disabled interface to display the above interface .

Digital control ：

Option control is as literally described Enabled Just don't disable ,Disabled It's forbidden ,Disabled and Grayed Out  It is disabled and grayed out .

Digital control is digital 0 Corresponding Enabled,1 Corresponding Disabled,2 Corresponding Disabled and Grayed Out.

As shown in the icon ：

The relevant characteristics of this attribute are shown in the following table ：

Next, a small demonstration in an experiment ：（ This experiment is in my other articles ）

In the above figure, we see the disabled palette named channel one and channel two （Disable）, Here I use digital control , Of course, we can use tabs to control .

The function shown in the figure above is when the button to disable the generator is pressed , Both channel one and channel two will be implemented ==2== function , That is to say == Disabled and grayed out ==. The front panel is as follows ：

3、 ... and 、 summary

The above is to disable the use of palette , If you have any questions, you can comment or send me a private message ！== thank you ！！==
