  • Page 8: Modbus - General Info

    • 5 Modbus - general info ODBUS GENERAL INFO Modbus is a communication protocol developed by Modicon systems. In simple terms, it is a way of sending information between electronic devices. The device requesting the information is called the Modbus Master (or the Client in Modbus TCP) and the devices supplying informa- tion are Modbus Slaves (in Modbus TCP servers).
