Timeout

Installed apps on the IEM OS that are subscribed to the event service, that you have activated during the creation of the app in the IE App Publisher, receive a notification when you perform a system event, for example an IEM OS shutdown or reboot.

When you click the Timeout Settings tile, the System Commands Timeout Settings screen is displayed:

In this screen, you set the maximum waiting time for these apps to acknowledge the triggered system event. After the set time has passed, the system event will be performed. By default, the maximum time is 5 minutes. Minimum value is 1 minute and maximum value is 60 minutes. To save the changes, click Update.

If the IEM OS does not get an acknowledgement from the app, the IEM OS performs the system event anyways. In that case, app data may be lost.

When you click the NTP Health Status Timers tile, the `NTP Health Status Timers screen is displayed:

Any changes of the NTP server status will be displayed in the Recent Events screen.
