Good morning waltgp,

Thanks for your question. The two PV800 lessons in Nano Basics aren't intended to be a dive deep into the PV800 since this is a Micro800 course.

That said, you should find the Function Key assignment under the Button Properties (typically on the right near the toolbox.)

You should also find a Multistate Push Button Object in the toolbox which you can assign three states and three images to mimic a three position selector switch.

Sincerely,

Shawn Tierney,
Instructor at The Automation School
