Good morning J. Overton,

Welcome to the The Automation School's pre-sales forum for questions about our courses.

Since your question is not about a course but more of a general Q & A question, please feel free to re-post it on our public forums at:

http://TheAutomationForums.com/forumdisplay.php?13-HMI-and-OI-Terminals

Please feel free to re-post your question there if you're still looking for an answer,

Sincerely,

Shawn Tierney
