1-247 are addresses of specific devices. With the exception of broadcast messages, a slave device always responds to a Modbus message so the master knows the message was received. 4511 Supported Modbus Function Codes: Command Function code...
Modbus slave addressing range: 1 - 247 (247 = default address) Modbus Parameter Storage: Saved in non-volatile memory in the 4511 device (Factory Default Values are marked in bold) Modbus RTU segment line termination: A 120 Ohm resistor should be installed on both ends of a RS485 Modbus RTU segment loop to prevent signal echoes from corrupting data on the line.
