Used defined textual unit
Deviating units on the device's onsite display are automatically converted to the corresponding Modbus
unit and the converted process value is transmitted.
7.4 Units of device variables
Measurement values which are mapped to device variables are transmitted with a defined Modbus
unitcode. The following table provides the information which unit code is used for a given sensor type and
sensor measurement value.
