Function code 4 is specifically designed for reading input registers from a Modbus slave device. In Modbus, a slave device refers to a peripheral device or equipment that is connected to a master device, such as a programmable logic controller (PLC) or a computer. The master device initiates communication with the slave device by sending requests in the form of Modbus function codes. When a master device wants to read data from input registers of a slave device, it uses function code 4. The input registers store data that can be read by the master device, such as sensor readings, status information, or other relevant data The master sends a request packet specifying the starting register address and the number of registers to read, and the slave responds with a packet containing the requested register values.
