Troubleshooting Alarm Server Connection Status for Color Animation
I am currently attempting to link a color animation to a rectangle that changes based on its connection status to the Alarm Server. Despite my attempts using "system\AlarmStatus='Connected'", I have not been successful. I also tried using RNA://$Global/
Although I have not personally tested it, consider using the function AE_HistoryStatus.AE_HistoryStatus( "My_FTAE_SERVER_Name" ). This function returns a value ranging from 0 to 8 that indicates the status of the connection to the alarm history database. The possible statuses are as follows: 0 for initializing the connection, 1 for being connected, 2 for being disconnected, 3 for starting logging, 4 for database definition deletion, 5 for failed logging, 6 for stopping logging, 7 for stopped logging, and 8 for alarm history not being configured. With 9 different states, using a color animation may not be ideal. Instead, consider using a multi-State Indicator for better functionality. Please note that this information pertains to the Alarm and Event server, and not the older HMI Tag Alarms. The alarm tags under the system folder are specific to the old method and do not apply to Alarms and Events.
I have experimented with your recommendation but am facing difficulties in achieving the correct format. I am currently attempting to simply display an integer as a test. The expressions I have tested include: 1. {AE_HistoryStatus(Alarm 4867)} 2. {AE_HistoryStatus(/Area1/Alarm 4867)} 3. {AE_HistoryStatus("/Area1/Alarm 4867")} 4. {AE_HistoryStatus("Alarm 4867")} 5. {AE_HistoryStatus"Alarm 4867"} 6. {AE_HistoryStatus:Alarm 4867}. It appears that the use of the open bracket is causing issues.
Have you experienced the benefits of using {AE_HistoryStatus("Alarm_4867")} yet?
Have you experienced the latest version of Alarms and Events, {AE_HistoryStatus("Alarm_4867")}? I can confirm that I have tried it myself, and it is indeed the new V13 release.
It appears that the AE_HistoryStatus feature was introduced in version 14. When I checked a device running version 13, I noticed that this feature was not included.
It sounds like you're on the right track, but have you tried checking the syntax and the data types for the expressions you're using? Sometimes, the Alarm Server connection might require specific triggers or even a refresh to update the status. Also, make sure that the Alarm Server is configured correctly within your project's settings, as an incorrect path can lead to those expression not being recognized. You might want to experiment with a simple test to output the connection status on a label first to ensure you're getting the right data before trying to link it to your color animation. Good luck!
