Please......... somebody help me.
I start 2 weeks ago to try all the existing examples for serial communication arduino modbus.
No-one example work.
I just want to compile a sketch modbus slave on my arduino Uno and control the slave's answers.
Now I read only illegal response or break connection.
I used ModbusPoll or Mtester with USB/RS485 cable converter and a shield RS485 on my arduino.
Thanks in advance.

Hi,
You should use simplemodbusng on your arduino and my other project http://minimalmodbus.sourceforge.net/ pc side to communicate with.
All is well tested, If you have a specific code please post a short examples that triggers the bug.
Hope this helps!
