When testing a display in FactoryTalk View Studio, is it required to stop test-display to change communication setup?

If I am in

FactoryTalk View Studio

testing a display and I want to change something in my communication setup, do I have to stop my test-display (or test-run) prior to doing so?

Yes. Nothing breaks if you do not stop the test; however, you may experience unexpected results. It is best to execute your test run and/or test display, stop that test, and then open the

Communication Setup

editor and make your changes.
