Read Input Register
The Read Input Register function reads data from input registers in the remote device. Data
can be written into the analog input or the analog output sections of the I/O database.
Any number of registers may be read up to the maximum number supported by the slave
device or the maximum number above, whichever is less. The read may start at any
address, provided the entire block is within the valid register range. Each register is 16 bits.
