These values are read using MODBUS function code 3 and written to using MODBUS
function code 6 or 16.
The parameters require 64 MODBUS registers for the scanner configuration (including
spare registers provided for future expansion), and 40 registers for each of the four
function-sets (including spare registers). This is a total of 230 registers per scanner. This
means that two MODBUS requests are required to access all the parameters for one
SF910i scanner.
The user must update an entire Tuning Function-Set in one MODBUS request to ensure
that all the parameters are consistent and that all are accepted or all are rejected.
