9.2 MODBUS Name and Address Table
Modbus response table is as follows. As users communicate with transmitters through PLC or Man-
machine Interface, check to see if the transmission of address subtracts 1 by default. If so, add 1 onto
each address to match the table; e.g. for Turbidity/SS measurement logic address 0035H (16-bit) or 53
(10-bit), if the output signal is subtracted by 1 by the PLC or Man-machine Interface, users must input
0036H (16-bit) or 54 (10-bit) to match the appropriate logic address.
