modbus function codes explained | modbus function codes | modbus fuctions | function code in modbus Read Coils (Function Code 01): This function code is used to read the status of discrete coils (binary outputs) in a Modbus device. It returns the current state of multiple coils in a single request. Read Discrete Inputs (Function Code 02): Similar to Read Coils, this function code is used to read the status of discrete inputs (binary inputs) in a Modbus device. Read Holding Registers (Function Code 03): This function code is used to read the contents of holding registers (analog outputs) in a Modbus device. It returns the current values of multiple registers in a single request. Read Input Registers (Function Code 04): Similar to Read Holding Registers, this function code is used to read the contents of input registers (analog inputs) in a Modbus device. Write Single Coil (Function Code 05): This function code is used to write a single coil (binary output) in a Modbus device. It allows the control of individual outputs. Write Single Register (Function Code 06): This function code is used to write a single register (analog output) in a Modbus device. It allows the setting of individual output values. Write Multiple Coils (Function Code 15): This function code is used to write the states of multiple coils (binary outputs) in a Modbus device. It allows the simultaneous control of multiple outputs. Write Multiple Registers (Function Code 16): This function code is used to write the values of multiple registers (analog outputs) in a Modbus device. It allows the simultaneous setting of multiple output values.
