The Modbus value therefore corresponds to the sum 90270
If the value of a data query for data address is 4186 = 2 (see tab. Data values number of decimal
places), the Modbus value bust be divided by 100. The result is then 902.7.
If the value of a data query for data address is 4015 = 5 (see tab. Data values unit total) The unit is
total galUS.
The end result for Total TA1 is therefore 902.7 galUS.
Notice The numbering of the register addresses starts at1, the data addressing at0. This is how e.g. when
reading register1 the data address0 is used.
Notice All units and the number of decimal places should be read out at least during initialization of the elec-
tronic unit, i.e. during switch-on, because these values can be modified manually.
Notice For parameter settings of the electronic unit via Modbus function 10(hex)=write holding registers (pre-
set multiple registers) can be used. Data exchange via the Modbus connection is not password-protec-
ted – avoid unintended overwriting of the total values or parameter addresses!
Notice All data can be read out or written in packages of up to 64words.
