Application Server 2023 R2 SP1 includes a number of new features, hot fixes, and provides support for the latest versions of Microsoft products. Refer to the GCS Technology Matrix for the list of supported Microsoft products.

Improved OMI web client

The web client for use with OMI ViewApps has been enhanced to eliminate many of the limitations that existed previously, and provide better alignment with the native behavior of desktop ViewApps.

OMI web client supported as Progressive Web Application

The OMI web client supports being saved as a Progressive Web Application (PWA). When an OMI web client PWA is launched, it displays a landing page listing all the deployed ViewApps. For an OMI web client PWA to work, the machine with the deployed WebViewEngine must be reachable.

OMI web client security enhancements

The system supports OS-user-based and OS-group-based security in the OMI web client. This includes support for the following MyViewApp namespace security attributes:

MyViewApp.LoggedInUserName (User Logon)
MyViewApp.LoggedInUserRoles (User Logon Roles)
MyViewApp.LoggedInAccessLevel (Access Level)

AlarmApp enhancements

The OMI AlarmApp has new columns available for alarm messages and ack messages. A new option has also been added to apply color or to blink an entire row, or just a single column.

HistoricalTrendApp enhancement

Follow Current Context now works for the HistoricalTrendApp.

Application Server instance name length

The maximum number of characters allowed for Application Server instances has been increased from 32 to 128.

Note that only instance names support 128 characters. Template object names continue to support a maximum length of 32 characters.
Graphics, Layouts, Screen Profiles, ViewAppNamespaces, ViewApps, InTouch ViewApps, and ViewEngines continue to support a maximum length of 32 characters.

Change Network Account utility

To simplify IT security tasks for multi-node systems, the Change Network Account utility, also known as .AdminUser Change Utility, lets you paste a plain text password into the utility. Copying the password from the utility remains prohibited.

Resolved issues

This table describes important resolved issues in AVEVA Application Server. Many of these issues were also included in Patch Releases 01 though 04 of System Platform 2023. Some issues that have been fixed in this release may not be listed.

Originating Issue	Related Issues	Case/SR Number	Description
3275787		960407245	In a multi-development setup, in the presence of simultaneous activities, the aaIDE.exe hung and then crashed, leading to closure of the application for all users. Specifically, when USER 1 had the IDE open with no active actions, and USER 2 was engaged in object imports, the subsequent opening of the IDE by USER 3 triggered the crash.
3306897		960366948	GRAccess-based applications could not be used because their use wrongly reset template option selections to their default values. This forced the re-embedding of graphic symbols in the template container graphic.
3321814		960402939	No exclamation point icon is visible on an instance when errors/warnings do exist for the instance.
3343835		960418008	For nested templates, the "Create Instance" function generates different generic names than before. In the previous version, the parent instance was given the name passed as a parameter, and the children were given generic names as in the IDE (nested template name + index). In the new version, all instances take the name given in the parameter with an index.
3356780		960421136	Redundant app engine assets appeared twice in the navigation bar (presumably once for the primary and once for the partner), and the faceplate did not display when the redundant app engine assets are selected.
3383589	3412404	960406922	After deployment, the Engine.Objects dimension and array are not updated.
3386280		960426261	After a disconnect, when MQTT reconnected, Store and Forward data was missing.
3397682	3022955	960429245	When you have a Parent object with a Graphic that contains graphics from Child Objects, use of the Select Alternate Symbol right-click option on the Child Graphic did allow selection of other Graphics on the Child Object, but when the user selected OK, the Owning object name was not set correctly.
3416027		960435416	Application Server 2023 was stuck at check-in at the 81% mark.
3421862		960437496	Application Server’s IO attributes were not getting data from the Telemetry Server (via PCS).
3423855		960438566	Some objects derived from object wizards lost inherited script function content after some unrelated objects were imported.
3447121		960440539	New internal alarm primitive names were getting reset to the old names and settings.
3474020		960449737	After validating objects on an Application Server 2023 P03 galaxy, instances that were derived from templates with object wizards reverted to the default settings of the parent template.
3447542		960426421	A null reference exception was encountered during testing of the OPCUA Service connecting OPCUA tools client software while users were browsing data.
