    4 Functionality 4.1 Communication, parameter setting, evaluation • The unit generates output signals according to the parameter settings� • Using an IO-Link capable parameter setting tool such as the FDT service program ifm Container the following options are available: - Reading current process values� - Reading, changing and saving current parameter settings and transmitting them to other units of the same type�...
  • Page 6: 4�3 Monitoring And Diagnostic Functions

    4.3 Monitoring and diagnostic functions • By measuring with two different, thermically coupled sensor elements (NTC, PT 1000) the unit automatically detects drifts and errors during temperature measurement with great reliability� • An average value is formed from the measured individual NTC and Pt 1000 values�...
  • Page 7: 4�4 Analogue Function

    The behaviour of the unit, e�g�, in case of failure of one of the two measuring ele- ments is defined by the parameter [drEd] → 8 Operation. 4.4 Analogue function • [OU2] defines whether the set measuring range is provided as 4���20 mA ([OU2] = [I]) or as 20���4 mA ([OU2] = [InEG])� • The analogue start point [ASP] defines at which measured value the output signal is 4 mA (20 mA for [InEG])�...
