| TUAPL05 | PandABox: A Multipurpose Platform for Multi-technique Scanning and Feedback Applications | 143 |
|
||
|
PandABox is a development project resulting from a collaboration between Synchrotron SOLEIL and Diamond Light Source started in October 2015. The initial objective driving the project was to provide multi-channel encoder processing for synchronizing data acquisitions with motion systems in experimental continuous scans. The resulting system is a multi-purpose platform well adapted for multi-technique scanning and feedback applications. This flexible and modular platform embeds an industrial electronics board with a powerful Xilinx Zynq 7030 SoC (Avnet PicoZed), FMC slot, SFP module, TTL and LDVS I/Os and removable encoder peripheral modules. In the same manner, the firmware and software framework has been developed in a modular way to be easily configurable and adaptable. The whole system is open and extensible from the hardware level up to integration with control systems like TANGO or EPICS. This paper details the hardware capabilities, platform performance, framework adaptability, and the project status at both sites.

| TUPHA159 | Malcolm: A Middlelayer Framework for Generic Continuous Scanning | 780 |
|
||
| 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. | ||

| TUPHA190 | Adaptations to CS-Studio for Use at Diamond Light Source | 880 |
|
||
| Control System Studio (CS-Studio) is one of the most widely-used display managers for EPICS. It is based on the Eclipse Rich Client Platform (Eclipse RCP), allowing for coherent integration of interfaces for different systems with common graphical elements and preferences. However, this user interface presents a different way of working to those from the previous generation of EPICS tools such as Extensible Display Manager (EDM) and Striptool. At Diamond Light Source, EDM has been used since commissioning in two different ways: for machine operations and for beamline controls. Both uses of EDM will eventually be replaced with CS-Studio and significant effort has been put into this transition. Two kinds of change proved necessary: adaptations to CS-Studio itself, and changes to the typical user workflows. This paper presents both types of changes that were needed to make CS-Studio a productive tool at Diamond. | ||

| THPHA068 | PandABlocks Open FPGA Framework and Web Stack | 1539 |
|
||
| PandABlocks is the open source firmware and software stack that powers PandABox, a Zynq SoC based "Position and Acquisition" platform for delivering triggers during multi-technique scanning. PandABlocks consists of a number of FPGA functional blocks that can be wired together at run-time according to application specific requirements. Status reporting and high speed data acquisition is handled by the onboard ARM processor and exposed via a TCP server with a protocol suitable for integration into control systems like "EPICS" or "TANGO". Also included in the framework is a webserver and web GUI to visualize and change the wiring of the blocks. The whole system adapts to the functional blocks present in the current FPGA build, allowing different FPGA firmware be created to support new FMC cards without rebuilding the TCP server and webserver. This paper details how the different layers of PandABlocks work together and how the system can be used to implement novel triggering applications. | ||

| THPHA184 | MalcolmJS: a Browser-Based Graphical User Interface | 1869 |
|
||
| A browser-based graphical user interface has been developed at Diamond. It is known as known as MalcolmJS as it communicates using Diamond's Malcolm Middleware protocol. The original goal was to communicate, via websockets with a PandABox in order to allow a user to examine and set attributes of numerous functional blocks within the instrument. With the continuing maturity of the JavaScript language, in particular the release of ES6, along with the availability of off-the-shelf reactive open-source JavaScript libraries, such as Facebook's React and Node.js, a rich set of tools and frameworks have entered the arena of user interface development suitable for control systems. This paper describes the design decisions based on these tools, experiences and lessons learned during and after the development process and the possibilities for future development as a generic, adaptable framework for instrument and control system user interfaces. | ||
