Tab. 1 Variables at the Modbus
Example for Total TA1 :
Send command: 010341000002D037
Result: 0103040001609E025B
The double word begins with the fourth byte (=00) and ends with the seventh byte (=9E).
Calculation of the value: 1*2^16+6*2^12+9*2^4+14*2^0=90270
Note : A change in the decimal places in the electronic unit must be taken into consideration when
evaluating data via the Modbus! The variable values are transferred without decimal point. The
conversion has to be taken into consideration during further processing.
The Modbus address is set in Menu 2.22, see "2.10 Address modbus", page 32.
Note : Data exchange via the bus connection is not password-protected! Write access deletes existing
values. Therefore we only recommend reading of the data.
