	Funding: Tango Community At the turn of 2020/2021, the Tango community faced the challenge of a massive migration of all Tango software repositories from GitHub to GitLab. The motivation has been a change in the pricing model of the Travis CI provider and the shutdown of the JFrog Bintray service used for artifact hosting. GitLab has been chosen as a FOSS-friendly platform for storing both the code and build artifacts and for providing CI/CD services. The migration process faced several challenges, both technical, like redesign and rewrite of CI pipelines, and non-technical, like coordination of actions impacting multiple interdependent repositories. This paper explains the strategies adopted for migration, the outcomes, and the impact on the Tango Controls collaboration.

	The Tango Controls collaboration has continued to grow since ICALEPCS 2019. Multiple new releases were made of the stable release V9. The new versions include support for new compiler versions, new features and bug fixes. The collaboration has adopted a sustainable approach to kernel development to cope with changes in the community. New projects have adopted Tango Controls while others have completed commissioning of challenging new facilities. This paper will present the status of the Tango-Controls collaboration since 2019 and how it is helping new and old sites to maintain a modern control system.

THBL01	Control System Management and Deployment at MAX IV	819
	B. Bertrand, Á. Freitas, V. Hardion MAX IV Laboratory, Lund University, Lund, Sweden
	The control systems of big research facilities like synchrotron are composed of many different hardware and software parts. Deploying and maintaining such systems require proper workflows and tools. MAX IV has been using Ansible to manage and deploy its full control system, both software and infrastructure, for quite some time with great success. All required software (i.e. tango devices, GUIs…) used to be packaged as RPMs (Red Hat Package Manager) making deployment and dependencies management easy. Using RPMs brings many advantages (big community, well tested packages, stability) but also comes with a few drawbacks, mainly the dependency to the release cycle of the Operating System. The Python ecosystem is changing quickly and using recent modules can become challenging with RPMs. We have been investigating conda as an alternative package manager. Conda is a popular open-source package, dependency and environment management system. This paper will describe our workflow and experience working with both package managers.

THPV011	Notifications with Native Mobile Application	883
	B. Bertrand, J. Forsberg MAX IV Laboratory, Lund University, Lund, Sweden E. Laface, G. Weiss ESS, Lund, Sweden
	Notifications are an essential part of any control system. Many people want to be notified of specific events. There are several ways to send notifications: SMS, e-mails or messaging applications like Slack and Telegram are some common ones. Those solutions frequently require some central configuration to record who will receive messages, which is difficult to maintain. ESS developed a native mobile application, both for iOS and Android, to manage notifications. The application allows the users to subscribe to the topics they are interested in, removing the need for a central configuration. A web server is used as gateway to send all notifications following Apple and Google protocols. This server exposes a REST API that is used both by clients to send messages and mobile applications to retrieve and manage those messages. This paper will detail the technical implementation as well as the lessons learnt from this approach.

FRBR04	Continuous Scans with Position Based Hardware Triggers	1069
	H. Enquist, A. Bartalesi, B. Bertrand, J. Forsberg, Á. Freitas, V. Hardion, M. Lindberg, C. Takahashi MAX IV Laboratory, Lund University, Lund, Sweden
	At beamline end-stations, data taking that relies on traditional step scanning, in which motors are repeatedly started and stopped, leads to inefficient usage of the x-ray source. This also increases the risk of sample radiation damage. We have developed a system where scans are performed while continuously moving the motors. To ensure stable repeatable measurements, the detector triggers are generated, in hardware, from the motor encoder positions. Before the scan starts, a list of positions is generated and as the scan progresses a trigger is produced as each successive position in the list is reached. The encoder signals from the motors are connected both to the IcePAP motion controller for closed loop operation, and a PandABox which is used as the trigger source. Control is from Tango and Sardana with a TriggerGate controller that calculates the motor positions and configures the PandABox. The scanned motor can be either a single motor, for example a sample positioner, or a combined motion like a monochromator. When combined motions are required, these make use of the parametric trajectory mode of the IcePAP. This enables continuous scans of coupled axes with non-linear paths.
