	The PANIC Alarm System is a python based suite to manage the configuration, triggering and acknowledge of alarms and automated actions in a Tango control system. The suite was developed at Alba in 2007 and since then it has been adopted by several other facilities and installations such as Synchrotrons and large telescopes, integrating in the process a large set of community-requested features. Its scalability is based on the stand-alone PyAlarm engines, that operate distributed across the control system; and the PANIC python API and user interfaces, that centralize the operation and configuration of the system. Each PyAlarm engine performs polled or event-triggered evaluation of alarm rules, complex logical operations and regular expression searches. The activation, recovery or reset of any alarm in the system can trigger actions like email, SMS, audible messages, local/remote logging, database insertion or execution of tango commands. This paper describes the evolution of the suite, its compatibility with other alarm handlers in Tango, the current state-of-the-art features, the compliance with Alarm Management standards and the future needs.

TUPHA165	New developments for the TANGO Alarm System	797

	The TANGO Alarm System, based on an efficient event-driven, highly configurable rule-based engine named AlarmHandler, has undergone a deep refactoring. The dedicated MySQL database has been dropped; the TANGO database now stores all the configuration whereas the HDB++ historical database keeps all the alarms history. Correlating alarms with any other engineering data is now much simpler. A dynamic attribute is provided for each alarm rule; this allows to easily build a hierarchy of AlarmHandlers. The AlarmHandler manages Attribute quality in the alarm rules and provides possible exceptions resulting in alarm evaluation. Mathematical functions, such as sin, cos, pow, min, max and ternary conditionals are available in the alarm formulae. The TANGO AlarmHandler device server is now based on the IEC 62682 standard.

	TANGO HDB++ is a high performance event-driven archiving system which stores data with micro-second resolution timestamps, using archivers written in C++. HDB++ currently supports MySQL and Apache Cassandra back-ends but could be easily extended to support additional back-ends. Since the initial release many improvements and new features have been added to the HDB++. In addition to bug-fixes and optimizations, the support for context-based archiving allows to define an archiving strategy for each attribute, specifying when it has to be archived or not. Temporary archiving is supported by means of a time-to-live parameter, available on a per-attribute basis. The Cassandra back-end is using Cassandra TTL native feature underneath to implement the time-to-live feature. With dynamic loading of specific libraries switching back-ends can be done on-the-fly and is as simple as changing a property. Partition and maintenance scripts are now available for HDB++ and MySQL. The HDB++ tools, such as extraction libraries and GUIs, followed HDB++ evolution to help the user to take full advantage of the new features.
