3.2.2 Modbus Function Code 02 (Read Input Status)
This function code is used to read the discrete input status bits in the DDC-100 Field Unit. The use
of this function code will provide the user with the input status bits that are used to develop holding
registers 9 through 13. The status bit inputs are contained in locations 10129-10208 for each
DDC-100 Field Unit and are defined in Table 3.4.
