    FocusParameterMonitor FPM Display of a measurement in the web browser The FPM has a web interface. This can be used to display a measurement as a HTML page. For the FPM with PROFIBUS or PROFINET, the Ethernet port may be located under the mainte- nance cover.
  • Page 87 FocusParameterMonitor FPM After a measurement, the single planes that have been measured are shown. It will display the power density distribution as a 2D display and the measuring values in tabular form. If a caustic has been measured, this is also presented in 2D. The calculated values are shown in tabular form.
