How Can I pass a Diagnostic service reference in TestStand

[JonathanRomanMQ]

Hello:

I have a test sequence and many VI's using Diagnostic Services in order to write some information by LIN Protocol. I need to open/close a diagnostic service session at each time that i execute a writing/reading command. 

I would like to keep alive a session until finish the writing/reading commands. 

I tried to pass the reference by a StationGlobal variable in TestStand after to open a session but it didn't work.

¿Does anyone know if this is possible?

If somebody has the same issue i already find the solution.

You need to create a Type definition in TestStand with all necessary variables that you have in your reference. Then you create a local variable as container and set up the new type definition that you create at the begining.

Now, you just need to map your variable in the output of your VI in the TestStand step.

I hope is usefully for you.
