	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.

Since 2015 the SKA Consortia joined in a global effort to identify, investigate and select a single control system framework suitable for providing the functionalities required by the SKA telescope monitoring and control. The TANGO Controls framework has been selected and comprehensive work has started to provide telescope-wide detailed guidelines, design patterns and architectural views to build Element and Central monitoring and control systems exploiting the TANGO Controls framework capabilities.

FRAPL01	Status of the Square Kilometre Array	1982
	J. Santander-Vela, L. Pivetta, N.P. Rees SKA Organisation, Macclesfield, United Kingdom
	The Square Kilometre Array (SKA) is a global project to build a multi-purpose radio telescope that will play a major role in answering key questions in modern astrophysics and cosmology. It will be one of a small number of cornerstone observatories around the world that will provide astrophysicists and cosmologists with a transformational view of the Universe. Two major goals of the SKA is to study the history and role of neutral Hydrogen in the Universe from the dark ages to the present-day, and to employ pulsars as probes of fundamental physics. Since 2008, the global radio astronomy community has been engaged in the development of the SKA and is now nearing the end of the 'Pre-Construction' phase. This talk will give an overview of the current status of the SKA and the plans for construction, focusing on the computing and software aspects of the project.
