New in Application Server and AVEVA OMI 2023 R2

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

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. The OMI web client is supported by the latest versions of the Google Chrome and Microsoft Edge browsers.

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, and are supported through the OPC client in the OI Gateway Communication Driver.

Alarm latching and alarm dismiss

If the Alarm latching feature is enabled, an acknowledged alarm that has returned to a normal value will continue to be displayed in the LATCHED alarm state. LATCHED alarms can be displayed in the current alarms mode to show that the alarms did occur. Alarms go to the LATCHED state when:

• ACKing an alarm from UNACK_RTN state.

  or

• Returning an alarm from ACK state.

To view the LATCHED state, enable the LATCHED state in the Alarms and events configuration screen of the IDE. You can dismiss the LATCHED alarms to remove the LATCHED alarms from the current mode of the Alarm Client Control grid. The dismissed LATCHED alarms will be visible in the recent mode of the Alarm Client Control.
