I am currently implementing MODBUS (serial) on an AT mega 16 processor.
For the diagnostics section I cannot really understand in what circumstances does the "Return Slave No Response Count" increment. As I am understanding it all the possible error counts are covered by the other count subfunctions.
If anyone can shed any light on the matter, it would be greatly appreciated.
