Error -17306 while running sequence

[Florian82]

Hi,

my problem is while running my sequence I get the error "Error -17306 unknown variable or property name'Step'. Error accessing item 'Step'."

This error occurs sometimes trying to run steps called from labview but most times trying to run the teststand standard "if" step and the standard "Pass/Fail Test", the "Numeric Limit Test" and the "String Value Test". It occurs on several other steps too. What makes this error really annoying is that this error doesn't allways occur on the same step. Each time it shows up at another step. And very view times it doesn't occur at all.

Please some help.

I have to add, that these errors don't occur if i run the sequence in single step debug mode.

Hi,

Would you be able to share some simplified version of the test sequence you created that would show isolated problem?

Thanks!

I could pin a lot of those failures down to the stationglobals.ini of TestStand. I still don't know why and what was wrong with the old one, because everything is working with other familiar sequences. But the stationglobals of my collegue is working better. still got some problems there.

And I still do have problems with those 'Step.' commands. I deleted most of them, know it works better. And there seams to be a problem with using references to send variables from VIs to TestStand sequences. I allways need to have a 0.2 sec wait step after a VI, otherwise i get the error because the reference is a 'null-pointer'.

The errors occur working through the subsequences in MainSequence. Sorry, it is a little bit much, but for fast testing i couldn't do it another way.

Dear Florian, 

do you still experience the problem with error code -17306 ?

What do you mean by 'Step.' commands? VIs that are called in the sequence?

Unfortunately I cannot test your code, because it references to VIs and hardware I have not at my disposal. 

Could you please post here the smallest working part of the sequence which reproduces your issue, including VIs that it is referencing to? Thanks

This error occurs whenever you are trying to access a variable which is not declared in the Sequence "Eg: Locals/Parameters/File Globals"

Sometimes some error may occurs randomly  try to compile your LabVIEW Modules.

thanks for your reply.

The teststand sequence is beeing started by a VI. This VI creates variables in the sequence. This part works perfectly fine. I double checked all the variables before writing here. Every variable is being created. It is a necessity for our teststation to work with dynamical created variables, that is why there are so many unknown variables in the sequence. But as I said, starting our program, all the variables are being created, no problems there.

Dear Florian, 

do you sill experience the problem with the delays?

As I wrote,  I cannot test your code, because it references VIs and hardware that I do not have. 

If it is not resolved yet, could you please post here the smallest working part of the sequence which reproduces your issue, including VIs that it is referencing to? Thanks
