The Basics of Modbus Protocol

[@jeremypearson9019]

Came here to learn about Modbus. Left trying to figure out how he learned to write backwards.

[@sshrek1996]

Forgot modbus for a moment.. I need to figure out how do you write this way ?

[@sswwooppee]

Thanks for the overview

[@regulardev]

Can you explain what was before Modbus? For e.g. contact closures can fuel level EMPTY or FULL. But it cannot tell fuel level at 37%. How were numbers represented/shared before Modbus?

[@march11stoneytony]

4-20 ma signal, where empty = 4ma and full = 20 ma

Great experience to watch this video 👏

Great Video Andrew. What software that you used for writing on the monitor..very interesting. Thank you.

[@DpsTV]

It's not software, actually. It's a piece of plexiglass with LEDs around the rim. You then write on it with neon "chalk" dry-erase markers. The markers pick up the light from the LEDs. Once you're done, you just flip the video in software. I've had to learn to thoroughly clean it between shots, and to find a "hole" to talk through after I finish my drawing.

Thank you for the video

[@TheFahadalisarwar]

You should go into more details

[@DpsTV]

You're right. Modbus is a hot topic. I will make more videos on the details, like Function Codes.
