Function 02(02hex) Read Discrete Inputs br Reads the ONOFF status of discrete inputs in the slave. br Request br The request message specifies the starting input and quantity of inputs to be read. br Example of a request to read 10...22 (input 10011 to 10023) from slave device address 4: br br Response br The input status response message is packed as one input per bit of the data field. Status is indicated as: 1 is the value ON, and 0 is the value OFF. The LSB of the first data byte contains the input addressed in the request. The other inputs follow toward the high-order end of this byte and from low order to high order in subsequent bytes. If the returned input quantity is not a multiple of eight, the remaining bits in the final data byte will be padded with zeroes (toward the high-order end of the byte). The byte count field specifies the quantity of complete bytes of data.
