I've built RS485 sensors. 4-20mA. And Bluetooth...
Now I need to build IO-Link. I have the specs, but... for Bluetooth, you need to become part of Bluetooth SIG to get an ID...
and I figure I need to do that for IO-Link.
Does anyone have a how-to-build-a-sensor (most of IO-Link's website is selling you on the value of such -- so much so, the EU has decided to do something that means I need to make my 4-20mA sensors... "intelligent."
Usually the dev boards are clear, but... not this time....
