Warning
:
MODBUS address is the address that is specified directly in the MODBUS protocol frame,
Registers in the controller have double Modbus address. The second address is for use in the range
from 0 to 9999 because not all software are able to use address above 9999. To have access to the
second address just subtract the value 55536 from the address listed in the tables.
Items in red colour are not available.
