Arduino with Modbus RTU

Projects Networking, Protocols, and Devices

Hi,

Is it possible to connect Arduino Nano, Mega or Uno to a device using Modbus RTU protocol?
I have read an articles stated that modbus library is not compatible with above arduinos.
Are there any workarounds?

Currently I am able to to connect 3 distance sensors to arduino Mega using TTL serial. But it takes 3 serial ports for the sensors which leave no rooms for further expansions such as serial display, serial printer, etc.

Fortunately the sensor also support Modbus RTU, which I support multi-points.

Pls advise.

Regards,
Bronson

The Library ModbusMaster by Doc Walker is working fine on Nano, Mega, Uno.

From these 3 microcontrollers I would chose the Mega due to its additional HW serials

Thank you for replying.

I will test the library as you suggest.

Thx
