unspecified error as subVI

[LuI]

I need an explanation:

The example 'IviFgen [ARB] - Generate Arb Wfm.vi' runs fine on my XP/SP2 with LV 7.11 and controls an HP33220A.

I copied its code into a specific VI that generates waveform data from files. It than generates an unspecific error when reaching the examples code.  I modifies the example bringing its controls onto the connector panel and called it as SubVI. Now the example generates a similar or identic error. When running the example again as toplevel VI it runs fine.

I was unable to programmatically invoke it as toplevel-VI cause the IVI name is converted to a hex number when making it variant and invoke-set controla s variant does not accept this.

Help is really appreciated now!

Hi Uwe,

which error do you get, if you run it as a subvi?

Mike,

I have modified that code and cannot exactly reproduce the 'unspecified error' when calling the example as subVI. I still have the example code copied into a case of my VI and this generates:

LabVIEW: Unspecified errorv occured

VI "ANSI-AAMI-EC13-Test_Fg aus Testdaten_03.vi" was stopped at IUseDCO 0x10B30 of SubVI "ANSI-AAMI-EC13-Test_Fg aus Testdaten_03.vi"

Hi Uwe,

and the only thing you do, is to connect all controls to the connector pane and use the example as a subvi? How do you stop the loop in the example?

Mike,

initially I wanted to invoke - set control value [variant], but it was sufficient zo open that FP and have the operator klick that <Stop>.

This is just a tool as one cannot set waveforms of 40k elements manually ;-(

Hi Lul,

          Can you post your code?

It'll take roughly 3 weeks until I'm back in office. Will keep up then...
