4 Modbus Register Addresses of Selected Physical Quantities
The following table is intended to provide assistance to the user.
It contains a number of selected Modbus register addresses of the most commonly used physical quantities and diagnos-
tic values. The measured values are scaled.
The Modbus register addresses are 0-based. If the transmitter is connected to a 1-based control system or software, the
Modbus register address in the following table has to be increased by 1.
