parameter value changes on ivi step

[JacobM123]

Hi

I am trying to pass a parameter value to an IVI step. The parameter name is Parameters.DMM and on entry to the sub sequence it has the value "DMM1".

I set the logical name of the IVI step to be parameters.dmm which I would expect would use the value "DMM1". however test stand seems to change the value of the Parameter.DMM to be equal to "Parameters.DMM" so my IVI step fails because there is no logical device called Parameters.DMM.

Any help out there?

Hi Jacob 

Thanks allot for your post and sorry for the late reply. I was wondering if you could post a short sequence that displays the issue you're having? If so I can try come up with a workaround or report it to R&D as a bug. 

Many thanks

Are you perhaps using the quote characters somewhere where you shouldn't be? For example, an expression like:

"Parameters.DMM" will evaluate to the string Parameters.DMM,

while an expression like:

Parameters.DMM will evaluate to DMM1
