Modbus register and Control Unit parameters
The Modbus protocol contains register or bit numbers for addressing memory. You must
assign the appropriate control words, status words, and parameters to these registers in the
device.
The valid holding register address range extends from 40001 up to 40722. When trying to
access other holding registers, the "Exception code" error is output
The process data are transferred into the register range from 40100 up to 40119.
Note
"R"; "W"; "R/W" in the “Access" column stands for read (with FC03); write (with FC06);
read/write.
