The Modbus scan registers can be used to create a custom Modbus data
block. This allows various non-contiguous Register Numbers to be
entered in this list and be read or written with a single modbus command.
The Modbus addresses for this block of data are entered here and the
actual data for each register will be displayed in the Modbus Scan Data
parameter for Modbus read data and data can be entered into the
Modbus Scan Data parameter for Modbus writes. The Modbus register
numbers for all parameters can be found in the C445 User Manual,
Appendix D. The starting Modbus address to read or write this custom
data block is register 3000.
