RS 485, Modbus Communication Protocol sensors with Arduino

[Amin Hajihosseinlu]

Is anybody familiar with interfacing a sensor that has Modbus communication protocol with Arduino.
I am aware that there are couple of libraries for Arduino programs, however I have another question. Has anybody done it before?

Appreciate any guide.

Modbus communication can take a few serial forms, I have done it with RS232.
What is the output format of the sensor?
M.

Thanks for your reply
It is Modbus, master/slave rs485.

Maxim has quite a selection for a RS485 Transceivers.
I have not used Arduino, but I have used the Modbus protocol with Pic's. so I can't help you there, are you familiar with the Modbus master/slave protocol?

I am familiar little bit, I have already purchased the Maxim IC max485 which convert TTL to RS485, If you have used it with PIC it should not be very different, I will use your expertise and experience.
Thank you
