[PSUBS-MAILIST] PLC Choice

[Stephen Fordyce via Personal_Submersibles]

Hi Alan,
I've also been using the VESC brushless motor controller (I use the FOCBOX
type, which is sold in Australia) for diver propulsion vehicles and they
are fantastic, with all their diagnostics and open source firmware. They
also can have a Bluetooth module added so everything can be monitored on a
smartphone app (Android).

Cheers,
Steve

Cliff, Steve, (mainly)
just an update on where I am with the plc choice.
Even though I had done a plc programming course I was getting totally
bewildered with all the I/Os & what sort of information I could extract
from my motor controller, BMS etc. Have bought a Vesc which is a small
electronic
brushless speed controller that can read rpm, amp draw & temperature from my
motors. I have over 60 I/Os & most are analogue.
I ended up contacting an electrician specialising in industrial automation
who is also an electronics geek. He is young enough to be up on all the
latest
technology. He is coming up with all sorts of ways of reducing the I/Os
using
raspberry pi etc.
So glad to leave it in his hands; will see what he comes up with.
Alan
