So does the HMI do all the controls or is there a small PLC somewhere? Or does it just monitor stuff and everything is manual?
Other than me manually opening/closing valves, this controls everything else.
I'm not familiar with Siemens, does the HMI directly do the I/O, or is there an I/O interface of some sort in between?
How do you turn pumps and heaters on and off?
Are you looking at bottling?
So many questions
Does this help?
PLC Brewhouse Control Panel
Siemens 12" touch screen
Brewhouse vessel temperature display and control
Brewhouse pump(s) control - on/off and speed
Lauter Tun Rake control - on/off and speed
Countdown timers
Includes 5x VFD's to control HLT pump, CLT pump, Wort pump, Kettle
pump and Lauter rake drive.
And yep, I'll be bottling.
