Thanks Robski, this is close, but not really the same thing, The Commu module allows native, and simpler RS485, but I will use Modbus.
Thanks

I am trying to use RS485 on the TAB5 main board, whilst there is a connector and SIT3088 I can't find UIFlow support for it, there is for the UART and CAN, but not RS485, have I missed something?
Thanks

I ended up making a PCB for this, I don't think the fine pitch connectors are sufficiently robust, so I connected to a simple PCB and then used a DC Jack plug on the board. MY 3D enclosure then mounts, via a laser cut plate to a UK double gang backbox

You would need to strap the board to do this. I created a board and getting it made at JLCPCB. The CANPwr board is quite expensive, reasonably enough, it is electrically isolated.

I have now bought both the PWRCAN and the Commu modules, neither apply power to SYSVIN or they do generate 5V on pin 28, which needs to be switched. I am using the TAB5 on a UK double gang plate with a 3D printed Bezel, you can't plug anything into the sides, as they would get removed.
It isn't practical to use the ExtPort2, as I would need to create a custom PCB to connect between the fine pitch fines to add a robust connector, are there any other options to power the TAB5 from behind?
Is there a Comms module ( I what to talk between 2 TAB5s over RS485) with a connector I can power the TAB5 from?
Thanks

I assume then the correct way to do this would be to use ExtPort2 and connect up to 12V through HVIN?

I have 2 Tab5 which I am powering through the Port A I2C connector. They won't power up when power cycled. IF I connect the USB C to aa hub, wait a few seconds, they then power up and stayed powered up. I have previously powered Tough boards through the I2C and it all worked fine.

@felmue Thanks Guys, I assume the switch is necessary to switch off the module, and save power when running on battery?

I am trying to implement a watchdog timer on the M5Tough, but it doesn't seem to be supported.
Surely this is a basic function on an Industrial device, can this be supported, I tried adding it in micropython, but I assume the class is not supported

I have a TAB5 and a M5STAMP-CatM module, there doesn't seem to be any way to connect the 2 The Stamp fits in the aperture in the case and there are pads on the TAB5 PCB but no pins. So do they connect?
