    Master Command List Appendix B Read Input Status (Function Code 02) Query This function allows you to obtain the ON/OFF status of discrete inputs (Modbus 1x range) in the addressed slave. PC Broadcast mode is not supported with this function code. In addition to the slave address and function fields, the message requires that the information field contain the initial input address to be read (Starting Address) and the number of locations that are interrogated to obtain status data.

  • Page 92: Read Holding Registers (Function Code 03)

    Appendix B Master Command List Because the slave interface device is serviced at the end of a controller's scan, the data reflect input status at the end of the scan. Some slaves limit the quantity of inputs provided each scan; thus, for large coil quantities, multiple PC transactions must be made using coil status for sequential scans.
