5.2.0 Release | Build

Released: November 12, 2019

What's new?

Version 5.2.0 is a functional update focused on the following new features:

NEW: Calculated Event Attributes

  • Event attribute can now be calculated based on an expression you configure.  For example, you may want to evaluate how long an event is taking and as a result set an attribute to "Micro stop" or "Breakdown".

NEW: Flow Server - Event Form Enhancements

  • Sometimes you'd like to restrict the dropdown options available for entry based on the value of other attribute selections.  For example, a "Micro stop" event may need to be categorized differently than a "Breakdown" event.  This can now be achieved by configuring an Enumeration Group.
  • Inserting, editing and splitting events is now available in a easy-to-use format.
  • Displaying event duration on an event form is now available.
  • Entering measure values for an event is now available.  For example, you can now manually enter an inventory value, a production run quantity, or a lab analysis value, for a specific event.

NEW: Flow Server - Charting

  • Event based table can now display the event duration, including the duration-to-date for open event periods.
  • A new event "timeline" chart can be used to display your events is a visual timeline.  For example, you can visually indicate where your equipment has been running or not.  Add attributes to the timeline for additional visual information.
  • A new mapping chart can be used to display your information geographically.

NEW: Flow Config

  • Model attributes can be configured with a set of options.  When linking an attribute to a measure, only these options are available for setting that model attribute.  If a model attribute has not options defined, then any value can be provided for that attribute.
  • The measure dependency view now displays any charts that depend on the selected measure.
