Hardware push button

I am trying to build an automated thermostat tester using labview. I'm going to try and test 6 t'stats at one time. I have most of it ready but I have a few doubts. I'm using Labview 8.5 on Windows 2000 with the NI PCI 6515 DAQ unit.
I am attaching my code here. As you can see it has start and stop buttons (soft button). But this is not how it's supposed to be anymore. They want a push button in hardware now. So our design fixture has a big push button for start and stop (momentary switching not a proper switch) (hard start-stop).
I want to know how to edit this VI in order to not have these soft buttons but to tie them up to a hardware button. I know I will have to use the DAQ to sense the momentary change in state but I don't know how I can do that and how to edit this without having lots to do.
All you help will be highly appreciated.
Thanks,
Shreya

Look at the dataflow demo I have attached. If you cannot figure out what it is doing part of the time, try running it with execution highlighting on. (The light bulb on the diagram toolbar). Notice that parts Two and Three have the indicators outside the case structures and use shift registers so no local variables are needed. Part One does not update LED 1 or String 1 effectively because it has neither the shift registers nor local variables. Parts One and Two are similar to your Unit cases, except that in the demo they always execute the same case on each iteration. Part Three is similar except for the way it handles delays. See below for why this matters.
Part Three shows an alternate Wait method which works well with state machines and allows prompt response to user inputs (Stop) or errors.
The picture shows one case of your program. Suppose this case is called in Unit 1 and the Reset93 case is called in Unit 2 on iteration 50 of the while loop. A call to Reset93 writes to a digital line then calls Clear Tasks. Clear Tasks calls Power Off which writes to a different digital line and calls Stop. Stop tells the while loop to stop executing.
Question: When does PowerOff (Unit 2) happen and when does the while loop stop executing?
Answer: In iteration 53 at least 183 seconds later. Iteration 50 does not complete until all the case structures and all other nodes inside the while loop complete. Since Unit 1 Case Dialog1 has waits totaling 183 seconds, iteration 51 will not start for at least that long. If one of the other Unit cases has a longer delay or has a delay in iteration 51 or 52 those delays would extend the time before stopping.

Hardware push button acting as mechanical switch (latch when released)

Hello,
I have a simple question. How can I have a hardware push button (momentary switch fed into DAQ board as a digital input) exhibit the same characteristics as a boolean with its mechanical action set to Latch when released?
Is it possible to do that?
Thanks,
r15
Solved!
Go to Solution.

Is the code implemented easier when a "latch when pressed" behavior is required?
The problem I am facing is that when I press the hardware button, the indicator "element" is incrementing as long as the button is pressed. I need it to only increment one time until I release the button and press it again.
Hence, everytime I press the button (no matter how long I keep it pressed), I want the indicator to increment only once to count the number of times the button is pressed.
I attached the VI below to make things clearer.

Please don't tell me you attached a VI that was set to run when opened.
I try downloading your VI and it popped up with a dialog box saying there is no disk in the drive, and to put a disk into \Device\Harddisk3\DR7. That or it seemed to be looking for an H: drive.
As for switches, look at page 21 of the manual http://www.ni.com/pdf/manuals/371303l.pdf. It shows a switch connection a digital input pin to ground. But also a resistor between the digital input pin and +5V to pull the voltage level back up when the switch is open. Although I'm not sure that the pull up resistor is truly critical.

How do I use a push button digital trigger with my 6034E DAQ board?

I am only a Lab View toddler.
I am currently using a push button, wired to PFIO/TRIG1 and DGND, with a anolog trigger. However noise is causing my program to be triggered. I was told that a digital trigger would help to reduce the random triggering. How do I create a push button digital trigger?
Thanks

Push button query!!!!!!! help needed

hello all,
I HAVE USED THIS LOGIC FOR MAKING THE DATA ASCENDING AND
DESECENDING,AND TRIED ALL THE
SOLUTIONS THAT WERE SUPPLIED BY MY FRIENDS IN THIS GROUP,BUT COULD NOT
CHANGE THE
VISUAL ATTRIBUTE OF THE BUTTON.I AM REPEATING MY QUERY.I WANT TO HAVE
THE
PUSH BUTTON TO SIGNIFY VISUALLY THE ASCENDING AND DESCENDING DATA I.E
WHEN THE
DATA COMES IN THE ASCENDING WAY,THE PUSH BUTTON
SHOULD HAVE A "inverted v"ACC CODE"" ALONG WITH NAME "ACC CODE" I.E IT SHOULD
LOOK LIKE "ACC CODE "ACC CODE inverted v "
AND WHEN THE DATA COMES IN THE DESCENDING WAY,THE PUSH BUTTON
SHOULD HAVE A " v".I.E IT SHOULD
LOOK LIKE "ACC CODE "ACC CODE' v' ".SO PLZ HELP me TO GET THIS .
Any changes should be made to nls_lang parameter in registry???????????
PLZ LET ME KNOW WHAT IS FONT THAT I SHOULD USE.U CAN CHANGE THE CODING
THAT I HAVE WRITTEN
IN THE "WHEN BUTTON PRESSED" TRIGGER OF ACC_CODE.
BEGIN
go_block('age_tran');

THANKING U

Hi Shiju,
U can use the combination of fornt slash(/) and back slash(\) to fulfil ur requirement.
For ascending u can use /\ and for descending u can use \/. Does this solve the purpose?
I think it will.

How can I open a .pdf file in a browser on a click on a push button

I am using oracle 10g developer suit for form designing.
There is a .pdf file in the application server.
I want it to open it in a browser when a push button is clicked.
Could you please tell me how can I do that?

hi
u can use web.show_document() for that.
but if you want to open pdf file only then use

How to get GUI Status(Push Buttons) in ALV Report

Hi Friends
I have a requirement in a way that:
Once selection-screen was processed,an ALV report has to come and above the ALV List,I need a custom GUI Status(4 Push Button) with Push Buttons Logic.
Once I had clicks on thesse push button,I need to display one more ALV List and above this List,again I need a custom GUI Status(2 Push Buttons) with Push Buttons Logic.
Can anyone throw some light how we can achieve this.
Thanks for your cooperation!

How to inactive the push button on tool bar of alv report

hi masters,
i m working on the ALV interactive report, in this report i have to do 2 different operation on 2 screen.
eg.- on first screen i have the push button for 'data' and on second screen i will have the push button for 'upload'.

HI Vicky ,
                  if u want an interactive ALV report , there are lot of forums already having the solution for that , but let me give u the solution anyway.
In the function module "REUSE_ALV_GRID_DISPLAY" , import parameters
     I_CALLBACK_PF_STATUS_SET          = 'FLIGHT'
     I_CALLBACK_USER_COMMAND           = 'BUTTON_CLICK'
has to be supplied to this function module . The PF status is where u hav created the two buttons , that PF status has to be given here .If the user clicks on the button then it is handled by the form routines . Inside the sub-routine based on the button the user has selected u could perform the action.
FORM FLIGHT    USING RT_EXTAB TYPE SLIS_T_EXTAB.
SET PF-STATUS 'FLIGHT' EXCLUDING RT_EXTAB.
ENDFORM.
Here the "Flight" is the PF_status .
FORM BUTTON_CLICK USING UCOMM type SY-UCOMM
                       SELFIELD type SLIS_SELFIELD.
CASE UCOMM.
    WHEN 'BUTTON!' .
write ur code for button 1.
WHEN "BUTTON"
*Write ur code for button2 .
end case.
endform.
for any queries reply back.

Hi,
You need to know wich view you want to add the new push button.
In trx. BSP_WD_CMPWB select the view and enhance it. Go to the view layout and check if you see something like this
        <uhtmlb:toolbar id              = "Toolbar"
                        buttons         = "<%= controller->get_buttons( ) %>"
                        maxButtonNumber = "3" />
If yes, and I think you will find enhance the method get_BUTTONS OF _impl class
Add the code
CLEAR ls_button.
ls_button-id       = 'New Button'.
ls_button-text     = 'New text'.
ls_button-on_click = 'NEWMETH'.
ls_button-enabled = 'X'
APPEND ls_button TO rt_buttons.
Create a method with name you used in on_click property.

How to add push button in report.

Hi,
how to add a push button in the standard list report and on clicking which the line-size of the screen should reduce from 300 to 100.
how to proceed.
Can anyone help me.

Hii Guhapriyam,
You can ceate PUSHBUTTON in selection-screen like Below
SELECTION-SCREEN PUSHBUTTON 2(10) text-004 USER-COMMAND CL1.
Create a variable to hold the processed PUSHBUTTON value like
DATA v_flag TYPE flag.
The PUSHBUTTON will be processed at the event AT SELECTION-SCREEN. So write your code like below
AT SELECTION-SCREEN.
   IF sy-ucomm EQ 'CL1'.
     v_flag = 1.          "Buttob clicked
   ENDIF.
START-OF-SELECTION.
IF v_flag EQ 1.
     NEW-PAGE LINE-SIZE 100.
ENDIF.
OR
The best way of doing this by setting PF-STATUS like
START-OF-SELCTION.
SET PF-STATUS 'ZSTATUS'. "Double click on this and set the pushButton in standard toolbar option and in function key specify the BACK, EXIT and CANCEL button .
Then write your logic at the event AT USER-COMMAND.
AT USER-COMMAND.
   CASE sy-ucomm.
     WHEN 'RED'.
       NEW-PAGE LINE-SIZE 100.
     WHEN 'BACK' OR 'CANCEL' OR 'EXIT'.
       LEAVE SCREEN.
     WHEN OTHERS.
   ENDCASE.
