Basically MODBUS protocol is many embedded applications trending. MODBUS can be used over RS232,RS485 or Ethernet. When single master is communication with multiple slave RS485 is prefferred. MODBUS firmware can be developed for three format which are i) Modbus-ASCII ii) Modbus-RTU iii) Modbus-TCP
Modbus consist of different function code for performing operations.
