Depending on the type of Modbus software used, the holding register addressing range starts either at 0x0000 or at 0x0001. If
your Modbus software starts addressing from 0x0000 you can use the holding register addresses shown in the table above. If your
Modbus software addressing range starts at 0x0001 then add 1 to the holding register addresses listed in the table above.
This is also true for the various test tools available for Modbus…
Tabdial32 starts at 0x0000. (
http://www.leroy-automation.com/free%20softwares.html
) The Tabdial32 tool does not
support the write single holding register command.
Modbus Tester (
http://www.modbus.pl/downloads.htm
) starts at 0x0001.
(**) If 2.4 byte is written the Remote control writes the 3 and 4 nr bytes also in his memory of the display.
