PROFIBUS PA electronics: mode of operation

The process variable to be measured is generally referred to as the input variable.
The input variable provided by the sensor is an isolated digital frequency signal. This is
evaluated in a microprocessor and made available via PROFIBUS PA. The data for
transmitter parameterization is stored in non-volatile memory.
