I've successfully configured a client-server SCADA model using Zenon 12 Energy Edition for a substation. The server-side functions as expected, with the alert icon flashing appropriately when alarms occur. I'm using an internal variable named "Alarm_Area_Status" with the "Intern -Driver for internal variables" driver object type.

However, the alert icon is not functioning correctly on the client-side Service Engine PC. Despite the "Intern -Driver for internal variables" being successfully sent to the client, the internal variable values do not update when an alarm triggers. All other variable types and drivers are working as intended.

Has anyone else encountered this issue, and if so, how did you resolve it?

Thank you for your assistance.
