2. Configure the HART variable PV (Primary Value) as "Level"
 PV (level) is not relevant for the calculation
3. Configure the HART variable SV (Secondary Value) as "Pulse rate"
 SV (pulse rate) is relevant for the calculation
4. Connect HART channels with the RSG45
5. Edit the linearization table in the RSG45
 Value pairs (max. 32): pulse rate of cascade (total pulse rate) to cascaded level
(total level)
The pulse rates (cnt/s) of all the FMG50 units in the cascade are added in the RSG45
and then linearized
