Hello Huijuan,
Just to be clear; I presume this is an "medm" exception you are
experiencing.
What host platform is medm running on (OS, OS version, CPU, etc.)?
Which version of medm?
Best regards,
Ron

Also, when clicked Tweak Go button in motorx_more.adl, same error occurs.
Any information would be appreciated.
