ALM, ALMI – Alarm activation

Block SymbolsLicensing group: STANDARD

Function Description
The ALM and ALMI block is used to generate an alarm. The alarm is active when the input U=on. The alarm must be defined by the ALARMS block and is uniquely identified using the id parameter. Active alarms can be displayed by special component in HMI. Status change of the alarm and its acknowledgment is also stored in the archive (if defined in configuration in the ALARMS block). The alarm can be acknowledged by setting the parameter ACK=on.

Remark: The system displays the acknowledgment status, allows the user to acknowledge the ongoing alarm and can display the acknowledgment status in the HMI and in the archive. Acknowledging alarms has no further meaning for REXYGEN itself and nothing depends on it. Whether alarms will be acknowledged depends on the filter settings in the visualization and the design of the entire system.

Inputs

U	Alarm is active when $U = on$	Bool

Outputs

iE	Error code	Error

Parameters

id	Unique identification number of the alarm. Alarm is disabled for $id = 0$ . Value $id = - 1$ means that alarm is identified by name (e.g. name of the block without ALM(I) prefix) not by id. $↓$ -1 $↑$ 65535 $⊙$ -1	Long (I32)
ACK	Set $ACK = on$ acknowledge alarm. The algorithm immediately reverts the parameter to $ACK = off$ .	Bool
av1..av8	Value associated with alarm. See description of the ALARMS block to clarify how this value is propagate into alarm description. $↓$ 1.79769e+308 $⊙$ -1.79769e+308	Double (F64)
