Error 537163 by writing values to CVT

[chrisosw]

Hello,

I get always the error 537163 (Tag Memory.vi<append>Tag 'SchaltenV3Vakuum') by writing a value to my CVT. "SchaltenV3Vakuum" is the name of my tag. I cannot see the reason of this error. Has someone an idea?

I have append the two VIs with the code, one for initialization the CVT-List an the other which writes the tag.

I use it with LV 2011 and it's running on a cRIO 9074.

Thanks,

Christian

Hi Chris,

when you don't supply information on your CVT implementation (source?, VIs?) we cannot help you on your question!

Please provide all information needed to solve your problem…

[chrisosw]

Hello,

I have added the source VIs? What other Information do you need?

Hi Christian,

we also need your subVIs used to handle the CVT. You only attached the main VI(s)!

[chrisosw]

There isn't more, one VI for the initialization of the Tag-List and another one which begin writing. I add the whole project.

Hi Christian,

you have installed a toolkit named "Current Value Table". I guess you got by using VIPM.

As I don't have this tookit installed I cannot comment on the behaviour of that toolkit nor test your VIs. That's why I said before: attach all needed VIs…

Did you read the manual for this toolkit and did you ask the programmer of that toolkit?

You can simplify some of your routines like this one:

I don't know why you multiply with 1000 to convert µV to mV…

One more idea:

You use the same CVT implementation on the "my computer"/host part of the project as well as in the RT target. Do you want to access the same value from both targets?

I use the crio for control of a hot isostatic-press. There are 3 loops : the pid-control and the profile control and the transfer between the cvt and the SharedVariables. This is for the control of the whole process from a touch-panel computer (TPC-2012)

I'm not able to transfer the data direct from the tpc to the crio with the CVT. So I use the shared variables. But the CVTs have a better performance so I use them on the crio. VIs on MyComputer are only for testing.

I use the CVT from VIPM. First in LV2009 and all works correct. But after the update to LV2011 (the latest version wich works with my TPC-201) I found the update to CVT 3. And after this the error occur. After initializing the Tag-List i try to write some values and get the error.

But there is a lack of documentation, lots of examples don't work with CVT 3, the Tag-Editor don't work anymore ...

last not least.

I use the routine you shown for converting the voltage of a thermocouple to the temperature. And the values for the thermocouple are mostly mv, in the other case i must change the values of the parameter-table.

Hi Christian,

did you read the help page for CVT? It provides you with detailed description and a specialized support forum!

[chrisosw]

Yes I know it, but it's for the Version 2 and the error is not documented.
