You can use TestStand in the development mode on your production machine just like at your development machine. No difference. So yes you can create new sequences, new vi's, etc. on your production machine. The debug license allows you to develop on your production machine. You can legally install the development environment on both machines, but you can only use one at a time. The purpose of the debug license is to save you money. Instead of buying two full development systems, you buy only one and buy the debug license (costs much less than the full development system). Since you can only work on one machine at a time, this allows you to debug your applications on the production floor, or even create new applications on the production floor. You cannot however, install the development system on your machine and a co-workers machine and use the debug license for the co-worker since it is quite possible that both of you will be using the development environment at the same time. This would be illegal.
