Error Occurred at Property Node

[M.Siddeq]

Hi..

 in the attachment please go to USonic application examples===>USonic_A_Scan, it gives an error on USonic_A_Scan config sub vi; Error 1055 occurred at property node.
your recommendations please

Note:this issue was a branch on an other thread, it is better to be separate..

I am grateful to  Dennis Knutson who made the modifications and helped me to understand

Error 1055 means an invalid reference. You can right-click on an error cluster and select "Explain Error" to get the description of the error. This means that somewhere along the way the code is not passing a valid reference to the subVI. The only reference I see is for the XY Graph. So, you will need to run that config subVI in highlight mode and see which node is actually generating the error. If I had to guess I'd say it's probably the "Old Cursor List" node. Cursor lists were changed along the way, and it appears this code, while recompiled for 2009, was actually written in an earlier version of LabVIEW. If that node is actually generating the error then the code will need to be updated to use the new cursor list structure..

The good news is u were right regarding the "Old Cursor List" node, it is actually causing the error.

The bad news to me is:now i need to modify a code thats look complex to me.

Any guidlines?

Heey

New finding: this type of error is also existing on tha scan config of the orginal lv ultrasonic kit (all scan config A,B and C), inspite of this, the examples are working perfectly!!! how to explain that

Hi

I guess there is progress, I replaced the "old cursor list" with "cursor list" then I changed the refnum control type from "waveform graph" to "xy graph" to be compatible with xy graph reference at the top vi,

the property node that was giving the error is perfect now and passing data to "plot config" and"cursor config" SubVis

The 1055 error appeared again in the sub vi "peak detector" where I stuck now,,,it looks to me every thing is alright because the same settings of the property node at previous Sub Vis are also here

If I overcome this and the remaining 2 Sub Vis tehn I am done

Your assistance please

Please upload your latest code.

The latst code is attached;

Alos, I could not figure out why when I run the top level vi it tells me that the data is geeting into the A-scan out (XY graph) while in the subvi A-scan config it stopps at Detect Peaks subvi???!!!

I really need assistance on this because till now I have done all what I know and it is not coming right..

Thanks

What do mean it stops at Detect Peaks? I don't have NI-Scope so I replaced the call to IVI Scope Acquire with a signal generation VI. When I ran the USonic_A_Scan VI I got no errors. Is it possible it doesn't like your data?

[M.Siddeq]

Data flow stops at detect peak sub vi when I run the A-Scan config in hilight mode, is it may be due to that the sub vi can not find peaks to detect?

Your thought about may be it does not like my data is my trend since yesterday and still battling to find out what is not compatible ,,,do you see in the code any part that can not treat data to XY graph?

 Thanks

Please have a look at the A-Scan config vi, check out the path data in - data out; the data is not coming out from the 'for loop' to the 'bundle'.

The data is not getting into A scan out, this why it gives me no error but I get no data on the display.

Whta do u think about this??

May be I am branching away from the thread title?
