The TANGO Controls Framework continues to improve. This paper will describe how TANGO kernel development has evolved since the last ICALEPCS conference. TANGO kernel projects source code repositories have been transferred from subversion on Sourceforge.net to git on GitHub.com. Continuous integration with Travis CI and the GitHub pull request mechanism should foster external contributions. Thanks to the TANGO collaboration contract, parts of the kernel development and documentation have been sub-contracted to companies specialized in TANGO. The involvement of the TANGO community helped to define the roadmap which will be presented in this paper and also led to the introduction of Long Term Support versions. The paper will present how the kernel is evolving to support pluggable protocols - the main new feature of the next major version of TANGO.

BLISS - Experiments Control for ESRF EBS Beamlines

BLISS is the new ESRF control system for running experiments, with full deployment aimed for the end of the EBS upgrade program in 2020. BLISS provides a global approach to run synchrotron experiments, thanks to hardware integration, Python sequences and an advanced scanning engine. As a Python package, BLISS can be easily embedded into any Python application and data management features enable online data analysis. In addition, BLISS ships with tools to enhance scientists user experience and can easily be integrated into TANGO based environments, with generic TANGO servers on top of BLISS controllers. BLISS configuration facility can be used as an alternative TANGO database. Delineating all aspects of the BLISS project from beamline device configuration up to the integrated user interface, this talk will present the technical choices that drove BLISS design and will describe the BLISS software architecture and technology stack in depth.

The TANGO Controls Framework* continues to mature and be adopted by new sites and applications. This paper will describe how TANGO has moved closer to industry with the creation of startups and addressing industrial use cases. It will describe what progress has been made since the last ICALEPCS in 2015 to ensure the sustainability of TANGO for scientific and industrial users. It will present TANGO web based technologies and the deployment of TANGO in the cloud. Furthermore it will describe how the community has re-organised itself to fund and improve code sharing, documentation, code quality assurance and maintenance.

Reactive Programming, and How It Fits Within Control Systems

V. Michel
MAX IV Laboratory, Lund University, Lund, Sweden

The MAX-IV synchrotron decided to adopt events as the main communication channel in order to increase both the responsiveness and reliability of its TANGO* control system. That means the tango (software) devices do not perform read hardware operation on client request but instead maintain a reliable communication with the hardware while publishing the data through event channels. Reactive programming** is an asynchronous programming paradigm oriented around data streams and the propagation of change. Instead of using the traditional imperative approach of maintaining the integrity of variables, a reactive program expresses the relationship between data streams. High-level tango devices (software devices aggregating data from other tango devices) make very good candidates for reactive programming. More precisely, it is possible to describe the attributes of those devices as relationships, where the input data comes from the event channels of lower-level devices. The facadedevice*** python library is an attempt to implement the reactive machinery within a tango device base class, and provides a descriptive API for defining the relationships in a clear and concise way.
