	The Daniel K. Inouye Solar Telescope (DKIST) is currently under construction in Hawaii. The telescope control system comprises a significant number of subsystems to coordinate the operation of the telescope and its instruments. Integrating delivered subsystems into the control framework and managing existing subsystem versions requires careful management, including processes that provide confidence in the current operational state of the whole control system. Continuous software Quality Assurance provides test metrics on these systems using a Testing Automation Framework (TAF), which provides system and assembly test capabilities to ensure that software and control requirements are met. This paper discusses the requirements for a Quality Assurance program and the implementation of the TAF to execute it.

TUPHA159	Malcolm: A Middlelayer Framework for Generic Continuous Scanning	780
	T.M. Cobb, M. Basham, G. Knap, C. Mita, M.P. Taylor, G.D. Yendell DLS, Oxfordshire, United Kingdom A. Greer OSL, Cambridge, United Kingdom
	Malcolm is a middlelayer framework that implements high level configure/run behaviour of control system components like those used in continuous scans. It was created as part of the Mapping project at Diamond Light Source to improve the performance of continuous scanning and make it easier to share code between beamlines. It takes the form of a Python framework which wraps up groups of EPICS PVs into modular "Blocks". A hierarchy of these can be created, with the Blocks at the top of the tree providing a higher level scanning interface to GDA, Diamond's Generic Data Acquisition software. The framework can be used as a library in continuous scanning scripts, or can act as a server via pluggable communications modules. It currently has server and client support for both pvData over pvAccess, and JSON over websockets. When running as a webserver this allows a web GUI to be used to visualize the connections between these blocks (like the wiring of EPICS areaDetector plugins). This paper details the architecture and design of framework, and gives some examples of its use at Diamond.

TUPHA212	Odin - a Control and Data Acquisition Framework for Excalibur 1M and 3M Detectors	966
	G.D. Yendell, U.K. Pedersen, N. Tartoni, S. Williams DLS, Oxfordshire, United Kingdom A. Greer OSL, Cambridge, United Kingdom T.C. Nicholls STFC/RAL, Chilton, Didcot, Oxon, United Kingdom
	Detectors currently being commissioned at Diamond Light Source (DLS) bring the need for more sophisticated control and data acquisition software. The Excalibur 1M and 3M are modular detectors comprised of rows of identical stripes. The Odin framework emulates this architecture by operating multiple file writers on different server nodes, managed by a central controller. The low-level control and communication is implemented in a vendor supplied C library with a set of C-Python bindings, providing a fast and robust API to control the detector nodes, alongside a simple interface to interact with the file writer instances over ZeroMQ. The file writer is a C++ module that uses plugins to interpret the raw data and provide the format to write to file, allowing it to be used with other detectors such as Percival and Eiger. At DLS we implement an areaDetector driver to integrate Odin with the beamline EPICS control system. However, because Odin provides a simple HTTP Rest API, it can be used by any site control system. This paper presents the architecture and design of the Odin framework and illustrates its usage as a controller of complex, modular detector systems.
