Application Server 2023 R2 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.

New features and enhancements

Operations Control and connected experience

Operations Control is a way to license Application Server and other AVEVA System Platform products. It is a subscription license for either or both of the AVEVA Operations Control packages, Edge and Supervisory. Operations Control includes unlimited use of all products in the product package for your defined set of users. If you use Operations Control, you can also enable connected experience.

Connected experience enables Single Sign-on (SSO) for all Operations Control products on a given node. It supports common user authentication, authorization, and access entitlements across AVEVA Operations Control products. It includes:

User authentication via a single common user ID, configured and managed within AVEVA Connect.
User authorization via roles, groups, and rules (allow/deny).
Single Sign On: After you sign on to a supported product, subsequent sign ons to that product or other supported products on the node are automatic.

Connected experience requires access to the AVEVA Connect cloud repository from each node where you want to use it.

Support for import of SVG as an Industrial Graphic

The Industrial Graphic Editor supports import of Scalable Vector Graphics (SVG) as Industrial Graphics. You can perform the following:

Import an SVG into the Industrial Graphic Editor. The graphic elements automatically get converted to an Industrial Graphic, which can include many primitives.
Insert the SVG while using the Image icon from the Tools panel of the Industrial Graphic Editor.
Use SVG for the UpImage and DownImage on a button.
Use SVG for the Quality & Status display icons under Styles configuration.

Improved user interface

The System Platform IDE has an improved user interface that provides object status at a glance.

New OMI Web Client

The web client for use with OMI ViewApps is completely new. The new client offers better performance, a look and feel more like the desktop client, and an easier way to make ViewApps available from a browser: you just assign them to an instance of the new WebViewEngine object type.

OPC UA scripting

You can now use Application Server object scripts and/or Industrial Graphics scripts to call OPC UA servers. Method calls are executed in the OPC UA server through the OPC UA client, are supported through the OPC client in the OI Gateway Communication Driver.

Alarm latching and alarm dismiss

Latching is a new alarm state that can be enabled for a Galaxy. When latching is enabled, an acknowledged alarm that has returned to a normal value will continue to be displayed in the LATCHED alarm state. Alarms go to the LATCHED state if you ACK an alarm from UNACK_RTN state or return an alarm from ACK state. LATCHED alarms continue to be displayed to show that the alarms did occur. A dismiss command will return alarms that are in the LATCHED state to normal.

Application Server gRPC support

To enhance the security of Galaxy Repository operations, gRPC can be enabled for the System Management Server. This allows all GR-related operations, such as deploy/undeploy and start/stop to be executed over a secure channel.

Application Server resolved issues

Original Issue	Related Issues	Case/SR Number	Description
1848600		960157869	Creating a new instance of a working, deployed OMI application caused all of the working instances of the application to need to be redeployed.
1860423		960174949	Intermittently, the Secured Write "Retrieving Reason Description" timed out and displayed the message Unable to retrieve Reason Description.
1877088		960176481	In dynamic text referencing for Integer alarms, comment did not work with String arrays.
1888024		960161993	While importing objects from a specific CSV file, the IDE closed with the message Connection to the Galaxy Repository has been lost. Archestra IDE will shut down.
1892267		960171722	If a platform was deployed when installing a patch for AVEVA System Platform, the AlarmClient and TrendClient controls were not updated. No warnings or error messages were written to the log.
1911736		960166135	While deploying a redundant engine, the bootstrap service encountered an error, stopping the engine and the platform. The error message generated was aaEngine.exe RedundancyPrimitiveRuntime2 Error INVALID HRESULT LINE 246 FILE <path>\RedundancyPrimitiveRuntime.cpp
1914761		960180506	Some objects were not updating dynamic data on the Application Object Server. Redeploying the objects fixed the issue.
1926125		960179494	Changing the SQL Server Compatibility level to 2019 made importing objects unacceptably slow.
1934343	1819846 1862300	960190420	There was a performance issue when using a derived template to create instances through GRAccess with a large Galaxy (Galaxy size over 2GB, 31K IO size).
1939546		960191284	InTouch values were not being updated due to an issue with the NmxSvc service.
1941500		960185850	When using the scan mode "Active on Demand" and warm redundancy for the backup engine, failover to the backup engine caused all items to become active.
1949369		960192655	Changing a limit alarm value did not cause the alarm condition to be re-evaluated for buffered attributes. A buffered attribute's alarm state did not change until the next time the attribute value was updated.
1969449		960196010	After writing to an attribute in the OPC client, the client that updated the attribute did not see the new value, while other clients did.
1988488	2118272	960200700	After upgrading AVEVA System Platform, a Galaxy which had not shown any object errors or warnings showed over 3000.

2127825		960111993	There were delays in data updates in an OMI application when switching between primary and backup servers.
2137381		960226495	If a client computer running the alarm control was rebooted, shelved alarms appeared in the control as if they were active. To correct this, each alarm had to be unshelved, then shelved again.
2138833		960214835	In some cases, adding a new symbol to a graphic corrupted the graphic, causing it to show a circular reference message. This could also affect other graphics in the same object.
2139129	2137841	960228455	After modifying a template, the template's child objects showed warnings. There were no warnings before the template was modified. Validating the objects cleared the warning state.
2145673		960230037	In AVEVA System Platform 2023, if you cleared the Associate Galaxy Graphics check box for an InTouch ViewApp template, the option remained selected when you opened the template again.
2149159		960221364	The output destination for some instances was changed from "---" to the default when a locked property in the instance's template was changed and the template was checked in.
2158159		960219741	Changes to a symbol that belonged to an area were not being saved correctly. When the area was closed and re-opened, the original symbol reappeared, without the editing changes.
2171127		960218196	The .AlarmInhibit setting was not retained when an Engine was redeployed.

2180583		960238103	After rebooting a platform, the platform engine crashed while the application engine instance continued to run. There were no MX communications and you could not deploy or undeploy objects on the platform.
2183152			Intermittently, when using a warm redundant engine, if the primary engine was disconnected from the network, causing failover to the backup engine, then reconnected to the network, the Object Viewer could not resolve references. Attributes showed bad quality with a Communication Error until the Object Viewer was closed and re-opened. This issue was specific to the Object Viewer; OMI VIewApps and InTouch Applications showed correct values.
2184681		960235646	When using Azure AD as the authentication provider, only groups without a space in their names were listed when adding new roles.
2219073		960229273	New users could write to an attribute from an OMI VIewApp only when on the Application Object Server where the object was running.

2213923		960227806	In AVEVA System Platform 2023, you could not retrieve the value of the TYPE parameter from a DIObject. The parameter seemed to be removed by the ScanGroupRuntime.
2219405		960236095	In AVEVA System Platform 2023, when using Azure AD as the authentication provider, once a user had logged into an OMI VIewApp using their user name and password, they could then log in to InTouch for System Platform using only their user name, without having to enter a password.
2292916		960253318	When using a redundant AppEngine, the View In Object Viewer feature did not automatically focus on the selected object.
2293862		960245764	The Cross Reference tab for an object did not always show all cross references.
2296755		960251997	Deploying objects that pointed to a DDESuiteLink object on another AppEngine on the same platform caused LMX warnings during or just after deployment. In addition, some objects, not limited to the ones that received the warning, showed bad quality in the Object Viewer.
2304964		960234377	The GR Platform aaEngine process kept using increasing amounts of memory until the system became unresponsive and showed the message Heap Create failed Not enough storage is available to process this command. At that point, the server needed to be restarted.
2320864		960262032	During some installations, the AVEVA NmxSvc service was not set up properly.
2322204		960245921	If failover to a backup GR node occurred after an alarm occurred but before it was acknowledged, acknowledging the alarm sometimes failed with the message Failed to Ack the Alarm; Operational error: Alarm Acknowledged Already.
2325393		960256256	Enhanced the logging of the application category component to better troubleshoot object deployment issues.
2329110		960259732	Improved check-in performance after adding options to a template.
2338358		960263766	In the galaxy browser, filtering by attribute did not work for device integration objects or RDI objects.
2354864	2167852	960269666	An InTouch application running in a remote desktop session would freeze for a few seconds to a few minutes, then resume working normally.
2357627		960264356	After turning on the Simplified Layout option in the System Platform IDE, the keyboard shortcuts for IDE features did not work. This continued until you restarted the IDE, even if you turned off Simplified Layout.
2365598		960271756	After some AVEVA System Platform upgrades, Boolean ASP arrays stopped working. The arrays had been configured following the instructions in Tech Note TN000022758 (legacy ID TN423).
2372346		960270563	Under certain conditions, when checking in a template that had had unrelated changes made, the AlarmSourceAttr attribute was locked in error.
2384675	2197622	960243658	When using a DDESuiteLink object to read from an OI.MQTT server, after a disconnection and reconnection, store-and-forward late data was being played back through the HMI and was missing from the Historian.
2396741		960275948	When "Enable advanced communication management" is enabled in the IDE, values for attributes stop updating when written to with a different datatype.
2396784	2339386	960278840	The AVEVA Galaxy Repository Service (aaGR.exe) was sometimes crashing randomly.
2412334	987524	960275032	After updating an OMI ViewApp and deploying it to two or more hosts, launching the ViewApp sometimes still launched the older version of the ViewApp.
2420563		960282853	After changing a template with a large number of child objects, the changes were not always propagated to all children. In this case, the save process reported that it was successful, but errors were recorded in the logger.
2422899		960284673	The Change Network Account dialog box was unreadable on a Chinese Operating System after upgrading to 2023 Patch 01.
2422443	2380893	960244101	Using a GRAccess application to change the Symbol Wizard option descriptions of a UDO changed the OMI ViewApp runtime behavior of the embedded symbol.
2435545		960278150	For some Galaxies, Galaxy load and validation took much longer after an upgrade to a newer version of AVEVA System Platform.
2442091		960265213	In the IDE, the properties window for an attribute was always too small when it first opened and needed to be resized.
2414287		960291144	After installing a Microsoft update, started to see "APPCRASH events for aaObjectViewer.exe and wm.exe in the Windows Logger after closing the Object Viewer. These events did not cause any problem with using the IDE.
2441229		960283947	The GalaxyBrowser pop-up window always opened to the last position it had occupied for any user. If the new user had a smaller monitor than the previous user, this sometimes caused the Galaxy Browser position to be completely off the screen of the smaller monitor.
2452008		960287309	After exporting a Galaxy from 2014 P01 and then importing it to 2023, the default element styles were missing from the new Galaxy.
2464781		960294256	With redundant engines deployed and redundancy alarms enabled, no alarm was generated when the primary engine shut down and the redundant engine took over.
2473677		960295264	In some cases, after an upgrade from 2014 P01 to 2023, customized alarm severity images appeared enlarged and distorted.
2476051		960297286	The IDE opens the wrong object in the Object Editor if you perform these actions, in order: Select an object (object A) in the Deployment pane. Select an object (object B) in the Templates pane. From the Home ribbon, select Open or Open read only. This correctly opens the Object Editor for object B. Close the Object Editor. Again, from the Home ribbon, select Open or Open read only. This time, the Object Editor opens for object A instead of object B, as it should.
2482518		960290054	When historizing alarm data using A2ALMDB, the displayed timestamp for buffered data was incorrect. It did not take into account the time zone offset from UTC.
2489138		960281235	Importing previously exported alarm messages sometimes failed with a timeout error reported in the log.
2493247		960300171	When there were complex visibility expressions in the Object Wizard Visibility Settings, the choices chosen for an instance did not display in the IDE, though they worked correctly in runtime.
2513357		960291831	After upgrading from System Platform2017 U3 SP1, when a new item was added in the PLC\OFS UPC server, the new object did not show any data until the OPCDA DI object was redeployed.

2567323		960225587	If an Object Wizard included a User Defined Attribute (UDA) with the buffered property set to true and an option to set the UDA to Used or Not Used, creating and saving an instance with the option set to Not Used caused the warning Buffered enabled UDA <attribute name> does not have an input source.
2574326		960297592	After working correctly for a period of time, the Web Client display showed ###Hatch#. Restarting the ASBService service fixed the issue, but it re-occurred after periodically. Log showed Failed to connect PDMS-Web. Error description: "No connection was established at the service endpoint".
2582433		960312547	After migrating from 2020 R2 SP1 to 2023 P01, deploying an instance created from a template that contained a series of User Defined Attributes caused multiple warning messages in the log. The deployment appeared to be successful, but attempting to undeploy the instance caused an object is not registered to the engine error and sometimes hung the engine.
2588645	2541429	960295797	If an Application Object Server hosting the primary object engines was unplugged from the SCADA network, then re-attached, the platform failed to restart.

Known issues

This section describes known issues that remain in Application SAerver 2023 R2 and in AVEVA OMI 2023 R2.

Issue Number	Description
Security mismatch	Some connected experience configuration scenarios can result in unexpected behavior. Scenario 1: Ability to access security tabs when an unsupported authentication mode has been configured. If a galaxy using Galaxy security has been created without connected experience, and then connected experience is configured, if you: Connect to the galaxy and change the authentication mode to Authentication Providers. Add a new group and cancel the changes. You will be able to access the security tabs in an unsupported authentication mode. Scenario 2: Cancelling read-only message box in the security editor closes the IDE. If a galaxy using Galaxy security has been created without connected experience, then the IDE is closed, and then you configure connected experience and login to the IDE with an AVEVA Connect user, when you: Connect to the galaxy and click Yes when the dialog appears. Launch a second instance of the IDE and connect to the same galaxy. Navigate to the security page in the second IDE. A dialog opens and asks if you want to open in read-only mode. Click No. The IDE closes (the IDE should not close in this scenario). Scenario 3: The Authentication Providers security mode can be enabled without configuring any roles. If you connect to a galaxy and select Authentication Provider security, and then navigate to the Roles tab, but: You do not add any roles. Click Save. The IDE will shut down. Note that changes should not be allowed in this scenario since no role is configured and there is no Administrator login support under Operations Control mode.
2897808	The SignedAlarmAck feature is not currently supported for Application Server and AVEVA OMI when AVEVA Operations Control connected experience is configured. Attempting to sign an alarm acknowledgement fails, and an error message is generated that warns of incorrect user credentials.
1869732	If the domain controller goes down and at the same time, an IDE user attempts to perform a change user operation, there is a slight possibility that Windows will display a crash dialog for the IDE. Note: This is a very rare scenario. Workaround: Restart the IDE to proceed.
1861501	Endpoints on remote nodes, including redundant SSO nodes, are not discovered when the Global Discovery Server is not available. As a result, logging in to a Galaxy using Azure AD credentials when the security mode is Authentication Provider is not successful. Workaround: For discovery of any endpoints that are not on the local node, then a GDS (global discovery) server MUST be available for discovery. You can configure a secondary GDS to avoid non-discovery, which can occur when the redundant SSO is on a different node. You can configure secondary discovery servers in the System Platform IDE. See the Application Server help for instructions on configuring multi-galaxy communication. You can also configure a secondary discovery server through the PCS Configuration utility. Open the PCS Services Configuration utility C:\Program Files (x86)\Common Files\ArchestrA\Services\aaServiceConfiguration.exe Open the Configure link (near the top of the utility window), the select Discovery Service from the menu. Enter a secondary node name for both the Local and Cross solution. "Local solution" is equivalent to Local Galaxy server in the System Platform IDE, and "Cross solution" is equivalent to Multi-Galaxy server.
1846869	When System Platform is configured with a standalone System Management Server (SMS) and Authentication Provider, other nodes pointing to the SMS node may not be able to reach the Authentication Provider on the SMS node for user authentication. Workaround: Use one of the recommended SMS system configurations described in the System Platform Installation Guide. Refer to the section "Recommended SMS Architecture Utilizing an Authentication Provider."
1842703	If, after configuring a node to connect to an existing System Management Server, you choose to make the node a redundant SSO server, the Configurator does not indicate that the Authentication Provider configuration parameters must be configured (green checkmark is still shown and the Configure button is grayed out). Workaround: Select the Authentication Provider configuration option and configure the parameters as described in the System Platform Installation Guide.
CR L00138837	AppEngine can crash due to calls made to API dlls even when using try/catch. This issue is specific to Nullable data types. The recommendation is to use wrapped API DLLs in Application Server scripting.
TFS 1404918	If a network failure occurs on the active engine node and Warm Redundancy is enabled, the last value is shown as NULL for slow-changing Tags. Workaround: Perform a SQL Insert or CSV Insert for the tag in question on the Historian side. This will restore the value in the Historian trend.
