The Industrial Raspberry Pi Forum

Hi Volker,

yes it makes sense, the RevPi polling approach should do it for now since no events are involved.

One more quick question related to the Arduino prototype: would it be possible to connect multiple Arduinos (modbus slaves) to the RevPi via a USB hub with different slave ids, based on the code sample you mentioned?

So with a hub like the one on the shop page for instance:

Thank you

Hi Enrico,
yes with several USB devices connewcted you will get several ttyX devices on the RevPi Core. Each one can be the base of a modbus RTU master configuration. You only need to use more than one virtual master module and that should work.
