440C-CR30 - Electrical Design and Programming, Pt1 Hardware CCW

When I first started learning plc logic, I had a very hard time separating what I had learned from relay logic and the plc logic I was trying to understand. For example if I say a xic witch looks like a normally open set of contacts, then I thought out in the field it had to be wired up to a normally set of contacts. What helped me understand was how you explained those as true if on , and true if off. It finally all kind of sunk in. By no means am I a PLC expert, I still get lost in some logic, Like when a machine gets out of sync, and the logic has like a 100 rungs of counter instruction in it. But I am a lot better at it than I was after watching a few of your videos a few years back. Thank you.

Question can you use a micro 800 plc to read and write to a guardmaster 440c CR30 using modbus RTU? I have found nothing on this at all no videos no paper instructions nothing. My setup is a Micro820, Panelview 800 series hmi and a guardmaster 440c cr30. I want to be able to trigger messages to read and write between all 3 but can't find anything on this I was wondering if you know how to do this or could make a video of this?
