MODBUS register:
Data type:
Access:
4205
3209
Float
read/write
! Note!
Function is not available unless the FREQUENCY setting was selected in the
OPERATION MODE function (4200).
Use this function to assign a variable to the END VALUE FREQUENCY(4203).
The value can be higher or lower than the value assigned to the VALUE F LOW.
Positive and negative values are permissible, depending on the measured variable
in question (e.g. mass flow). You define a measuring range by defining the VALUE
F LOW and VALUE F HIGH values.
User input: 5-digit floating-point number
Factory setting: Depends on nominal diameter [kg/h] or 2 [kg/l] or 200 [°C]
! Note!
Note that values with different signs cannot be entered for VALUE F LOW and
VALUE F HIGH, if SYMMETRY is the setting selected for the MEASURING
MODE function (4206). In this case, the message “INPUT RANGE EXCEEDED”
appears on the display.
