  At Alba, the Controls Section provides the software that is needed to operate the accelerators, the beamlines and the peripheral laboratories. It covers a wide range of areas or subsystems like vacuum, motion, data acquisition and analysis, graphical interfaces, or archiving. Since the installation and commissioning phases, we have been producing the software solutions mostly in single-developer projects based on the personal criteria. This organization scheme allowed each control engineer to gain the expertise in particular areas by being the unit contact responsible to develop and deliver products. In order to enrich the designs and improve the quality of solutions we have grouped the engineers in teams. The hierarchy of the product backlogs, represents the desired features and the known defects in a transparent way. Instead of planning the whole project upfront, we try to design the products incrementally and develop them in short iterations mitigating the risk of not satisfying the emerging user requirements. This paper describes the introduction of the Scrum framework as the product development strategy in a service oriented organization like the Computing Division at Alba*.

  The Equipment Protection Systems and Personnel Safety Systems of the ALBA Synchrotron are complex and highly distributed control systems based on PLC's from different vendors. EPS and PSS not only regulate the interlocks of the whole ALBA facility but provide an extense network of analog and digital sensors that collect information from all subsystems; as well as its logical states. TANGO is the Control System framework used at ALBA, providing several tools and services (GUI's, Archiving, Alarms) in which EPS and PSS systems must be integrated. PyPLC, a dynamic Tango device, have been developed in python to provide a flexible interface and enable PLC developers to automatically update it. This paper describes how protection systems and the PLC code generation cycle have been fully integrated within TANGO Control System at ALBA.

  The Alba Controls Group develops and operates a diverse variety of controls software which is shared within international communities of users and developers. This includes: generic frameworks like Sardana* and Taurus**, numerous Tango*** device servers and applications where, among others, we can find PyAlarm and Panic****, and specific experiment procedures and hardware controllers. A study has commenced on how to improve the delivery process of our software from the hands of developers to laboratories, by making this process more reliable, predictable and risk-controlled. Automated unit and acceptance tests combined with the continuous integration, have been introduced, providing valuable and fast feedback to the developers. In order to renew and automate our legacy packaging and deployment system we have evaluated modern alternatives. The above practices were brought together into a design of the continuous delivery pipelines which were validated on a set of diverse software. This paper presents this study, its results and a proposal of the cost-effective implementation.

  TANGO is a distributed Control System with an active community of developers. The community features multiple services like Archiving or Alarms with an heterogeneous mix of technologies and look-and-feels that must be integrated in the final user workflow. The Viewer and Commander Control Application (VACCA) was developed on top of Taurus to provide TANGO with the user experience of a commercial SCADA, keeping the advantages of open source. The Taurus GUI application enables scientists to design their own live applications using drag-and-drop from the widget catalog. The VACCA User Interface provides a template mechanism for synoptic-driven applications and extends the widget catalog to interact with all the components of the control system (Alarms, Archiving, Databases, Hosts Administration). The elements of VACCA are described in this paper, as well as its mechanisms to encapsulate all services in a GUI for an specific subsystem (e.g. Vacuum).
