TrendMiner 2019.R2

15th of April 2019

The 2019.R2 release contains the following new functionality and improvements:

New Functionalities

  • NEW DashHub: a new central location for you to quickly and conveniently put together your favourite TrendHub views and ContextHub views in the form of resizable tiles, to create dashboards of your choice. DashHub acts as a homepage for your top views where you can click on any chart and go-through to the view itself (in TrendHub or ContextHub) to explore the underlying data in more detail.
  • Context item fields: add extra structured information to your context items, by adding fields such as quality results, batch numbers or a property from a 3rd party system. You can exploit this additional information to filter your views.
  • Extended OSIsoft PI Event Frames integration: event frames synchronized from OSIsoft PI are enriched with their corresponding attribute data as additional fields on context-items, unlocking visualization, filtering & sorting capabilities in ContextHub.
  • Visualize context items directly in TrendHub: context items in ContextHub can now be opened directly in TrendHub at a push of a button. Your view will be set to the time period of your context items and the attached attributes or assets will be added to your view.
  • Improved ConfigHub: introducing a completely re-styled interface for system administrators to monitor the key services of TrendMiner, manage the application license back-ups, and configure security in one central location.

Application Enhancements

  • Unified application top-bar: common top-bar enabling easy navigation between TrendHub, ContextHub and the new DashHub.
  • Export image: (stacked) trend plots and scatter plots can be exported to a PNG, for reporting purposes. A list of tags and layers are included in the export.
  • Updating TrendHub views: from this release on, it is possible to save the changes you made to a TrendHub view without first opening the view in edit mode.
  • Visualization of context items on assets and attributes: in TrendHub, when adding attributes via the asset browser, context items on these attributes and their direct ancestors are now also visualized, next to the context items which are directly on the tag.
  • Additional filter options in ContextHub: additional filters for description and all extra properties added via the context fields are now available for ContextHub views.
  • Configurable columns in ContextHub table view: the table now also lets you configure which columns need to be visible, so you can display important properties on your grid.

Bug fixes

  • When modifying formula tags, unusual data are immediately cleared from the cache and correctly handled in the comparison table and searches.
  • Occasional performance issues related to the memory management of the service that runs the searches are resolved.
  • Context-item search: Attributes pop-up now also works with long list of attributes.
  • Issue which saw monitors switch off when retrieval of LDAP groups are failing, addressed.

Known issues

  • It will no longer be possible to edit ACL entries in ConfigHub when downgrading from 2019.R2 to 2018.R2.
  • Scooter values may change when zooming in after adding the scooter. This is due to the fact that scooters currently interpolate the data points on the chart.
  • The back button of the browser does not correctly restore the panel state.
  • Tag grouping is not yet remembered as part of the view state, and may be lost when refreshing the view or loading a saved view.
  • When calculated tags are deleted, they cannot be created with the same name again.
  • Exporting data from a view may fail with too many filter periods activated.

Important: Migration of user accounts

As from this release, usernames in TrendMiner are case insensitive. Accounts with matching usernames (variations in upper and lowercase usernames) will be merged, which might have the following side effects;

  • saved work from older duplicate accounts can appear when you log in;
  • your preference settings such as tag colors and recommendation engine settings from one of the duplicate accounts will be persisted to the remaining account, which might overwrite the settings of the last used account;
  • you might lose your admin role since the setting from one of the duplicate accounts will be persisted to the remaining account;
  • your level ACLs on user names will be lost when your casing does not match the casing used in AD/LDAP.

Synopsis functionality

NEW! DashHub

DashHub consolidates all the available information about your production processes you want to see, into one dashboard; providing you an instant overview of your TrendHub and ContextHub views, without having to locate information each time you open TrendMiner.


Click on a tile (using click through icon) of your choice to be instantly directed to your view of interest in TrendHub and ContextHub, with all the flexibility normally afforded to you by TrendMiner, when you want to dig deeper into your data.

Note: Use this for creating dashboards that can serve as campaign overviews, operating period comparisons, incident analyses, …


Note: Use this to attach meta information like batch numbers and quality results for a batch record, weather data, OEE figures or information on your periods of loss.

Context fields

Add extra properties to your context items with the context fields configuration that was added to TrendMiner. Administrators can now attach extra properties called ‘context fields’ to a context type so users are presented with extra information fields when filling out their context items.




Filters on context fields

You can target context field information in your context views using the existing filter framework to ask meaningful questions to your process, such as; was a certain property called Methylenchlorid in a range of 5 to 60?


Configurable columns in ContextHub tables

The ContextHub grid now lets you configure which columns need to be visible, so you can display important properties on your overview, such as, the amount of loss on items of Performance loss.


Extended OSIsoft PI Event Frames integration

The built-in TrendMiner connector to PI Event Frames now synchronizes the attributes from event frames to context item fields. Use this feature to take advantage of your OSIsoft PI Event Frames infrastructure to kick-start your analysis in TrendMiner;

  • adding contextual information to your process data;
  • defining a set of interesting time-intervals using filter criteria on the event frame attributes;
  • visualizing and overlaying event frames to compare situations of interest.

Important: Upgrade to Plant integration version 3.1.3 or later is required to include this additional functionality.

Unified application top-bar

A common top-bar allowing for easy navigation between TrendHub, ContextHub and the new DashHub.
