Patch 01 (Nov 11, 2026)

Known Issues

• 5220884 - Common Platform plugins in Configurator appear unconfigured after Patch 01 is uninstalled

  In the event that Plant SCADA 2026 Patch 01 needs to be uninstalled and reverted to the original release, two Common Platform plugins in Configurator, System Management Server and Federated Identity Provider, will appear to be unconfigured. Note that the configuration has not been lost, it just does not display correctly in Configurator. All services should continue to function as configured. To resolve the issue, reapply the previous configuration and click the Configure button on each plugin.

Alarm Server

• 5185685 - Alarm server stops working due to Process Analyst alarm pen separator

  If the Windows locale setting specifies a decimal separator that is not the dot character, displaying an alarm pen in the Process Analyst control may have caused the alarm server to stop working. Alarm pens can now be displayed regardless of the locale settings.

Alarms

• 5023595 - Alarm server stops when a standby server finishes synchronizing

  If a time stamped alarm was configured with an empty Variable Tag field, then the alarm server could stop unexpectedly. This may happen when a standby server finishes synchronizing with the main server, or when a standby server takes the role of the main alarm server. The alarm server can now handle time stamped alarms without a variable tag configured as these types of alarms are not evaluated. The project compiler now also shows a warning for any time stamped alarms that have an empty Variable Tag field, allowing the user to discover and correct the configuration before running a project.

Client

• 4920209 - Genies do not display correct state information

  Multi-state text, color and symbol set objects would display correctly in all cases when used on a standard page. However, if they were used in Genies, then there were cases where the object could display incorrect state information. Where there were blank states for particular multi-state display items in a Genie substitution, these state values would not be persisted correctly. In some cases, this would lead to either later states in the object also being persisted incorrectly or displayed in the incorrect state. Runtime now takes account of these empty states in Genies so that the client uses the same behavior as multi-state objects placed on a page.

Graphics Builder

• 4943453 - Graphics Builder stops working when all symbols in a symbol set are cleared

  This occurred after all of the symbols configured in a symbol set were cleared. If a new symbol was added to a position after the last position of the previously deleted symbols, Graphics Builder would stop working when OK or Apply were selected. This no longer occurs.

Runtime

• 4712758 - Periodic Events calling ServerInfoEx stop executing after a period of time

  Periodic Events that call the ServerInfoEx function will no longer stop due to the function being blocked.

Runtime Manager

• 5194020 - Runtime Manager and Connectivity Service Manager may stop working at startup when Windows is not English

  If the Windows display language was not English, or the language used for the original Windows installation was not English, then Runtime Manager and Connectivity Service Manager may have not worked when started. These applications will now start regardless of the display language.
