How do I set an environment variable in CANoe from TestStand?

How do I set an environment variable in CANoe from TestStand?

I'm pretty sure I can do it using the ActiveX/COM adapter in TestStand, but I'm not exactly sure how.

Hi Jaime_C

I think it is possible to use the Active X for that task. - I do not use that.

In my case i am using a small .net wrapper around CANoe.Interop Assembly

This is working pretty stable.

For more information just visit these threads:

Depending on your task there a other possibilities:

I am thinking on Vectors FDX-Protocol or even on ASAM XIL 2.0.0 Stanard  if you are using CANoe 8.2.x

If you are faoumos with LabView you can read/Write direcly in from CANoe in a LabView variable.
This uses also FDX

and there some Examples available.

Hi j_dodek,

Thanks for the reply.  I did see those threads when I was searching for a solution but I wasn't able to complete my task after reading them.  I'll read them a little closer and try again.

Also I'll give you some context for my problem.  I'm using TestStand 2014 to test my product, but I won't have a prototype for several weeks so I'm using CANoe 8.2 to simulate the DUT on the CAN bus.  I'm manually changing environment variables so that CANoe sends CAN messages with the signal values I need to proveout my tests.

Because this is a temporary solution I don't want to spend a lot of time developing a programmatic interface to CANoe, but if it's a matter of hours it would be well worth it.

Hi jaime_c,

just for understanding. Why setting enviroment variables? Starting some Capl stuff with them?
Do you want to load and start your CANoe config with TestStand, too? Or do like to hook on CANoe
and write the enironment variables.

At the moment on my machine is no CANoe available. But i think with 3-5 .net CANoe interop assembly calls

this hook should be possible in TestStand.

Yes, I'm using the environment variables on a panel in CANoe, and a CAPL nodes sets the CAN signals according to the environment variables.  Right now there's a message box in TestStand to prompt me to set the controls in the panel but I would love to set them programmatically from TestStand.

I don't need to load the cfg and start CANoe, I just need to hook into a cfg that's already running and set the environment variables.

Hi Jaime_c

I also wanted to know how many step are requiered to do a simple hook.

I hooked on Systemvariables because in my projects i prefer them.

The hook is done for Vetors Example:

C:\Users\Public\Documents\Vector\CANoe\8.2\CANoe Demos\Demo_CAN_CN\Easy\Easy.cfg

With it you can turn on and of the ignition key

Hope that helps

Juergen.

OH you can do that with 5 Steps (if you are using right variables....)
