ALM, ALMI – Alarm store value

Block SymbolsLicensing group: STANDARD

Function Description
The ALM and ALMI blocks are used for generating alarms. An alarm is activated when the input U changes to on. Each alarm must be defined using the ALARMS block and is uniquely identified by the id parameter (see 10). Active alarms (i.e., with U=on) can be displayed in the AlarmsTable visualization component. Records of the alarm state change and its acknowledgment are stored in the archive if allowed in the ALARMS block configuration. An alarm can be acknowledged by activating the ACK=onparameter.

Note: The system allows displaying the acknowledgment status, acknowledging an active alarm, and can display this status in both the HMI and the archive. However, the REXYGEN system does not operate further on the acknowledgment and no functionality depends on it. Decisions about acknowledging alarms depend on the filter settings in the visualization and on the specific system design.

This block does not propagate the signal quality. More information can be found in the 1.4 section.
