Features

Axiom

WARNING OF BREAKING CHANGES

The script engine in Axiom has been significantly changed. The result is that Axiom applications with scripting may no longer work correctly until the script is modified for the new scripting engine. If you are concerned about this and wish to have your scripting applications converted before upgrading, please contact Canary Support.

Scripting Updates:

File conversion attempts to convert old scripts to new script with no guarantee that scripts will not break. Simple scripts should convert, but more complicated scripts may need to be modified manually. The application will still load if scripts do not work after conversion and the editor will report errors in code with a shortcut to open script editor at the breaking location.

Documentation w/ examples built into Axiom

Per screen (only compiled if screen has scripting)

Recompile screen script without save/reload after script edit

Axiom Applications/ChartFiles Updates:

Converts files on service startup (keeps old files for optional downgrade or conversion fixes if issues are found)

Performance improvements when loading applications/charts

Property Names Updates:

Changes to make names more consistent across controls

Changes to better indicate property purpose

Editor Updates:

Performance improvements when editing

Touch support improvements

Added breadcrumb (single select)

-  Shows all parents of selected control

-  Shows shortcut actions for selected control

Added breadcrumb (multi-select)

-  Shows all controls selected

-  Shows shortcut actions common across selected controls

Properties organized by groups

Screen management UI changes

Asset controls/properties unavailable if no asset templates available on local view

Script controls/properties unavailable if user is not admin (anonymous is no longer an admin user, but anonymous users can be given script access by modifying a settings.json file on the server)

Tag browse context improvements (opens at asset instance context)

        

Controls Updates:

Can only change “Name” of controls when scripting is enabled. Outside of scripting, the “Name” of a control has little significance.

Grid Updates:

Asset performance improvements

New GridRow control

Editing does not add control to next row on paste (can copy entire row)

        

AssetTemplate Updates:

Performance improvements

Editing not limited to first instance

Header/Footer stylistic changes

Control Limits Updates:

are no longer used.

Can assign an Asset to the Panel control.

Added ability to show a scale on the Spark Chart with the high and low of the scale.

A Spark Chart will allow one scale to be configured and auto scale the one that is not
configured.

Created better scale bounds for discrete tags (0-1).

Changed scales to only show significant digits to give more trending area.

Reworked scale sizing especially when scales were staggered.

Added the "Live Scroll Percent from Live Edge" to Axiom. This was an option in Trend Link.

Added scale dragging, resizing and hi/low scale edits.

Added Display property to Linear Gauge to be "Standard", "Fill", or "Cutaway". The "Fill"
display will have a scale next to the "Cutaway".

Provided a new function Fallback(,) for adhoc trend calculation to allow a user to provide a value
when an input trend's pixel doesn't have a value.

Added Browser only "Full screen" button and "Esc" or F11 to toggle Full Screen mode.

Added icon in menu bar to Add Trends without opening Edit dialog.

Setting the "Aggregate Interval" to 00:00:00 in the export will output the raw data (only
when a value or quality changed).

Removed aggregates "Start", "End" and "Delta" which are replaced with "Startbound", "Endbound"
and "Deltabounds".

Reserving licenses for a multi-tenant security group will limit multi-tenant users of that
group to the number of reserved licenses.

Added better prompts to save scripting changes.

Added option to stay logged in until cookies are cleared from the machine.

Added a CanaryBasePath registry entry to move meta data (charts, applications, sender buffer)
to a user defined location.

Added ability for the Historian to send annotations to a redundant historian.

Added ability to execute adhoc event queries and find events functionality to the Web API.

Annotation audit was changed to use Axiom user credentials in place of Windows credentials.

Powershell script examples to call Web API for process data & raw data and export to CSV file.

Enhancement to Historian trend vectors to prevent file corruption when being split.

Collectors Changes

Added MQTT Sparkplug B Collector.

For OPC UA Collector, users can specify a full endpoint of an OPC UA server in place of host name, port.

Reworked the CygNet Collector to rebuild the tag list in the background and then swap it in
after a resync.

Added several new options to CSV import.

Added logic in CygNet Collector/Sender/Receiver to externally store tag properties in a
SQLite database and make the Views Service aware.

Bug Fixes

Axiom

Fixed duplicate session creation in axiom audit from the web interface.

Fixed parsing of tags with "\" escape character in front of embedded "." so the legend properly displays tag names.

Fix to allow Administrators to add folders under Read Only directory.

Axiom will rename any reserved names used for screens or controls without throwing an error.

Historian

Fix to allow the Views service to fully load the browse tree for large models. Accessing the
Views while it was loading could cause slow down of the system.

Fixed a case in the Historian when viewing an annotation over 512 bytes using the Admin.

Collectors

Fix bug to allow OPC UA Collector to reconnect to UA server when the UA server no longer has the
Session ID.

Excel Add-in

Fixed Excel Add-In problem with Adhoc Events returning data for Cloud tenants.

The Excel Add-In was changed to release the license/connection after every Add-In call.
