Modbus function code 3 is one of the several function codes defined in the Modbus communication protocol. Function code 3 is used for reading multiple registers from a Modbus device, typically in a slave device. Here's a breakdown of how Modbus function code 3 works: Request Format: The request message sent by the master to the slave consists of the following components: Function Code: 3 (0x03 in hexadecimal). Starting Address: The register address from where the read operation should begin. Quantity of Registers: The number of consecutive registers to be read. Response Format: Once the slave receives the request and processes it, it generates a response message that includes the following information: Function Code: 3. Byte Count: The number of bytes in the response, which is twice the number of registers read. Register Values: The actual data read from the requested registers, represented in a sequence of bytes.
