The date of last load of data to the database (see section Moving through the list of alarms) is refreshed when changes in the database appear.

If there is no any change in the database in 5 minutes, the CUT field is forcibly updated and then is updated once a minute. At the same time there will be a gap from the current system time by 5 minutes. After coming of new information from any of the Agent of Control, the CUT become equal to the current system time of the computer.

Loading data to the database is performed by the Data loader for Monitoring module.

If files with technical information are received from Agents of Control (e.g. camera enabled), these files are loaded to the database with a period specified while configuring Data loader in the Loading period (sec) parameter, 10 seconds by default. If files with information on alarms are received from Agents of Control (e.g. vibration sensor triggered), this information is loaded to the database immediately.

After each load to the database, a message is sent to the Control panel interface component to update the information.

If, after receiving files with technical condition, Server of Control determines that object state has not changed, then nothing is loaded to the database. This is why the timer is used to forcibly update interfaces (see section Data loading from database to the interface objects).

In the Alarm date field in the interface objects, the time of alarm information load to the database after receiving it from the Agent of Control is displayed, not the time of alarm appearing at the site.

Note.

To enable alarm registration with the time it emerged on site, create the TimeAlarmFromAgent key in the Windows registry and set it to 1 (see Registry keys reference guide for more details on the key and the Working with Windows OS registry section of Axxon PSIM software. Administrator's Guide for more details on how to operate registry keys).
