Override On/Off valve in while loop

[systemcrash]

How are doing the initialization part at DAQmx start ?share the code with all modules included or the image of your program

[ucbeoha]

That beyond me im afraid.

i have only ever DAQ Assisstant to run mutliple lines, or single line inputs to DAQmx so i dont know how to initialize this VI.

[systemcrash]

Have modified aeastet's VI.  Try this program and let us if you get any error 

[ucbeoha]

Yes i tried that earlier by merging some of your VI with that one.

I still get an error. (attached) I had to re-write the VI in 8.5 but i presume its the same. (i also changed the line in to the correct link)

[systemcrash]

Ok here you are doing wrong, see the comment in the VI which I modified, Input lines should be like this,

cDAQ1Mod1/port0/line0,cDAQ1Mod1/port0/line1,cDAQ1Mod1/port0/line2,cDAQ1Mod1/port0/line3,

cDAQ1Mod1/port0/line4,cDAQ1Mod1/port0/line5,cDAQ1Mod1/port0/line6,cDAQ1Mod1/port0/line7

The attached VI has only one line but the selection is "one channel for all lines" .

So select all the lines in DAQmx create channel VI, and let us know if you get any error in the create channel VI itself.

I tried a few different things but still get the error.

I also now can't seem to get the DAQmx write to work with a test task. I get the same -200524 error.

However if i open up Measurement & Automation explorer and run the same task from there its works perfectly!

Oh Brother , NI 9472 is 8 channel DO, my bad man, in the input also include "cDAQ1Mod1/port0/line7"

so your new input should be "cDAQ1Mod1/port0/line0 to cDAQ1Mod1/port0/line7" , I had written this in previous response, the error code just says you aren't using all the inputs but you are trying to write to many,

Haha, i cant seem to get the number of channels in the task to match the number of channels in the data.

For the 'lines in' i have selected line 0 - 7: cDAQ1Mod1/port0/line0:7

For the 'ine grouping' i have selected 'one channel for each line'

the error i get is:

200524

Number of Channels in Task: 8
Number of Channels in Data: 9

If i use line 0 - 6, i get the error:

200524

Number of Channels in Task: 7
Number of Channels in Data: 9

If i use lines 0 - 8, i get the error:

200170

because channel 8 doesnt exist

If i change the 'line grouping' to 'one channel for all lines' then i get the error:

Number of Channels in Task: 1
Number of Channels in Data: 9

[systemcrash]

ha ha interesting isn't it the below selection is not ok

For the 'lines in' i have selected line 0 - 7: cDAQ1Mod1/port0/line0:7

For the 'ine grouping' i have selected 'one channel for each line'

Attached is the same VI with simple modification and I bet this should work for you, have comments where changes has been made and where you need to make changes.

Let me know,

[ucbeoha]

Its working!

Thank you so much for your help, both of you!
