Class Description


This class monitors a Tango device attribute. A formula is applied on two consecutive attribute readings. If this formula is true, a voice alarm message is sent to the Control Room. The attribute to be monitored, the voice alarm message and the formula are defined as properties. <p> The device attribute <b>IsAlarm</b> has to be polled to force the attribute reading. The polling period is the delta time between the two consecutive attribute readings. In the formula, <b>previous_attr_value</b> has to be used to reference the previous attribute reading while <b>attr_value</b> has to be used to reference the last attribute reading

AlarmTriggerScalar: DevString This read-only attribute is set to the present "AlarmTrigger" property value which is the alarm formula
AlarmMessageScalar: DevString The message sent to the text talker device in case of alarm
MonitoredAttributeScalar: DevString The full monitored attribute name (device name/att name)
EnabledScalar: DevBoolean This read-write attribute enables, when set to "true", the emission of a vocal message alarm

Class Description


This class is simply an alarm generator for the cube used in ESRF data center. The cube is a cube with servers installed on two sides of the cube. Several cooling units (6) are installed in this cube to cool down the servers. This class manages alarm when some problems are detected in the cooling system
