Reef Tank Screen Controls

[Dweaver]

I'm working on a EXT 150 build in my house, things are progressing well. I have an automation direct P2-550 PLC to control the reef with the needed IO cards already. I will have a touchscreen monitor beside the tank going back to a headless Cmore HMI to do most of the functions.
Please have a look at the attached screenshots and let me know what you think and if there's anything you think I should add.

They call them EMO buttons . See the red button in the yellow circle in the back of the tool. That is an EMO button and when pushed it shuts the tool down completely.
