I wasn't aware. Very interesting.

I wouldn't say I work in industrial automation, but we are building a
machine for mineral analysis. We're not using Qt for the machine control
parts in this project though (but we are using PyQt for various GUIs, but
that's for remote control, not close to the hardware).

Modbus comes to mind as a protocol you might want to support, in its
various incarnations (TCP, UDP, serial, ...). It's a very widespread
protocol still, despite its age.

I don't know what scope you have in mind for this module. I looked briefly
at the code, and the interfaces seems quite general
(read/write/configuration parameters).

Other protocols we use at work are various hardware vendor specific
protocols over RS-422 and RS-485, so had we used Qt we would have used
QtSerialPort. Modbus was the only thing that came to mind right now.
Currently we use pymodbus, which is very well-written, if you need
inspiration.

Qt for industrial automation is an interesting prospect though.
