Logging local variables to a database

[sunds]

Hi!

I have followed the instructions in "Logging a New UUT Property to a Database in TestStand" in order to be able to log my local variable under Database Options/Columns/Parameters/Expression. My problem is that I can't access my variable in the Expression field. I can access my global variables, but I would like to log local variables as well. What am I doing wrong?

Thanks, Nina

Nina,

local variables are only valid in their "area of validity". If the local variable is part of your MainSequence, this area of validity is left as soon as you leave the MainSequence and return to the ProcessModel. So it is no surprise that you cannot access that variable. You can either pass the value of the variable to the databaselogging (which might require some changes within the ProcessModel) or you switch it to be file global.

The third option, which is propably the best, is to pass the variable from the step (where the value is written to the variable) to the ResultList using AdditionalResults (TS 4.1 and above) or Step.ReportText....

hope this helps,

Norbert
