  • tarting batch jobs or other programs.
Online Measurement Data
  • All measured values that are created transmitted by the measurement devices in realtime .
  • Data management of all measured points.
  • Measured values are available either as line graphs or bar charts in the online measurement mode.
  • Line graphs are always up-to-date (older data will be deleted, FIFO-principle).
  • Display of double y-axes with two units (e.g. current and voltage synchronously) possible for measurement data.
  • Multiple measurement devices can be displayed in the same graphs for each unit.
  • Colours in the graphs can be individually changed.
Historical Measurement Data
  • Measured values that have been saved in accordance with defined rules for averaging times in the device or by reading out the device into a central database .
  • Each value receives a timestamp as well as the corresponding device ID.
  • Administration of the data saved in the database, sorted by parameter, year, month and day.
  • Selective marking of the data guaranteed.
  • Annotating the bar charts / line graphs or histograms with headers and comments.
  • Display of transients and events in the transient or event browser.
  • Missing measurement data during particular time periods or unrealistic measurement information can be displayed by means of a flag browser.
