RADE Applications EN-STI-ECE-MTA

The Challenge Linux Windows Mac GPN TN DB CMW RBAC Timing Files PLC DAQ OBSTACLES Different protocols, libraries, file types, hardware layers. -> To teach LabVIEW to understand them all? Different platforms (Windows, Linux, Mac) Different networks (GPN, TN) To make your LabVIEW application communicate with the accelerator, you have to go through all these obstacles. (It would be a maze without RADE :) ) RADE Applications EN-STI-ECE-MTA

Initial Requirements Fast programming Rapid learning curve Drag and drop GUI development Wide range of analysis libraries Light/independent environment LabVIEW Integration with CERN infrastructures Applications that are developed rapidly, that can be easily maintained even though the implementation time is short. Two aspects: RADE based on LabVIEW (LabVIEW covers many of the requirements, but we need some more.) Light: no database declarations, no external libraries (everything encapsulated in LabVIEW) LabVIEW: all in one (no editor/compiler separately) RADE Applications EN-STI-ECE-MTA

RADE Framework Training Support Templates Configuration files Documentation LabVIEW DB Files JAPC libs PLC CMW Java Based on LabVIEW (covers many of the requirements already) 1) Communication with different front-ends and protocols 2) To properly use the communication libraries, we have created templates, config files, help documentation 3) RADE offers you a space in nfs where to store your config files (centralized location in nfs) RADE Applications EN-STI-ECE-MTA

RADE Core Technology LabVIEW user application LabVIEW C/C++ shared lib
Server Server Server 3 different mechanisms: 1) Natively in LabVIEW 2) Shared libraries 3) Connection to a server LabVIEW <-(HTTP)-> Tomcat server <-> Java services Next slide: what this architecture means to the user (it’s simple, just the beautiful LabVIEW palette) Java Java Java SDDS PLC MTA-lib RBAC RIO SQL TGM ALARM eLogBook RADE Applications EN-STI-ECE-MTA

RADE Palette How the programmer sees RADE. RADE Applications EN-STI-ECE-MTA

Coping With Large Applications
“RADE phase one” resulted in complicated applications that had to be maintained. -> Next step was to take care of the applications. - Large applications, maintenance, multiple developer communication etc. Short-life applications (“We’re gonna use it just for a month”) becoming part of the infrastructure (totem, post mortem) Some times they changed to long-term application. They have to be maintainable. -> we needed development rules and ways to work - Programmer can change, protocols might change, etc. Many different ways to do the same thing RADE Applications EN-STI-ECE-MTA

Large Application Requirements
Fast programming Rapid learning curve Drag and drop GUI development Wide range of analysis libraries Light/independent environment LabVIEW Integration with CERN infrastructures Source control and distribution Dedicated templates Applications that are developed rapidly, that can be easily maintained even though the implementation time is short. Two aspects: Animate new req. After existing RADE Applications EN-STI-ECE-MTA

Source Control The main source control system at CERN is Subversion RADE Applications EN-STI-ECE-MTA

State Machine Template
Several design patterns and concepts in the form of templates, adapted to RADE and CERN specific requirements RADE Applications EN-STI-ECE-MTA

Development help RADE design patterns and templates LabVIEW Guides: cern.ch/enice/RADE-Guides Code review: make LabVIEW code beautiful Use templates -> create clean code RADE Applications EN-STI-ECE-MTA

Outline MTA Why RADE? The challenge Coping with large applications RADE today Hands On session RIO: Live data from the front-ends RBAC: Role based access control SQL: CERN Database connections MTAlib and OpenG toolkits RADE Applications EN-STI-ECE-MTA

RADE Input/Output (RIO)
Live data from the front-ends RADE Applications EN-STI-ECE-MTA

What is RIO? Client applications RADE Input/Output (RIO) InCA
JAPC InCA CERN front-ends RADE Applications EN-STI-ECE-MTA

JAPC or CMW? Which protocol to use: in GPN use JAPC not in GPN, use CMW DIP (Data Interchange Protocol) to transmit data from accelerator to experiments. JAPC and InCA could be replaced by DIP. Only publisher/subscriber. To get and set data CMW was implemented. Then we could think of JAPC as an extension for Java development. InCA JAPC RADE Applications EN-STI-ECE-MTA

RIO: Basics 1. 2. 3. RADE Applications EN-STI-ECE-MTA

Get data from front-end

Set data to front-end RADE Applications EN-STI-ECE-MTA

Subscription to front-end data
Put operation.vi in a loop Check for timeout and error RADE Applications EN-STI-ECE-MTA

RIO data types Field name in LV = field name of device
Field type in LV = field type of device Japc2Lv_T2-abcopm02/Mixed: Field name Field data type D Double Bool Boolean C2D300 String [ ] I642D300 I64 [ ] [ ] C1D300 String RADE Applications EN-STI-ECE-MTA

Exercise Get, Set and Subscribe data on a CERN device
Goal: Implement GET/SET/Subscribe operations for CERN device using RIO Toolkit. RADE Applications EN-STI-ECE-MTA

Quiz 1 The device “PR.GSQDN1/CCV” has the following fields: lambdaX: I32 data: Double msg: String Which of the following Data Type is not correct? 1. 2. 3. 4. RADE Applications EN-STI-ECE-MTA

Quiz 2 The device “PR.BPM/Setting” has the following fields: bucketBBB: I32[ ] bucketSelect: I16 gain: I32 Which of the following Data Type is not correct? 1. 2. 3. 4. This is a trick. All are correct. RADE Applications EN-STI-ECE-MTA

Quiz 4 Which VI is used to execute SQL queries for CERN databases? SQL.vi Where can we find it in the RADE palette? RADE -> SQL RADE Applications EN-STI-ECE-MTA

Quiz 5 How to extract signal data from LHC logging Database? SQL-MA.vi -> lhclog RADE Applications EN-STI-ECE-MTA

MTA-lib OpenG: Community reviewed to a certain extent. One has to know that the VIs exist to use them. No performance guarantees. RADE Applications EN-STI-ECE-MTA

OpenG community Non-NI LabVIEW community Several green “time-saving” VIs Many polymorphic VIs → build executable to improve performance Non-NI LabVIEW Communities: – Forum and wiki – Forum and file repository - One of the few non-NI LabVIEW communities. You’d like to have something more in the MTA palette? -> Let us know RADE Applications EN-STI-ECE-MTA

MTA-lib: Data Palette Variant: A container that can contain different data types. Great for generic programming, but can add overhead. RADE Applications EN-STI-ECE-MTA

OpenG Use case: Variants containing generic data. RADE Applications EN-STI-ECE-MTA

MTA-lib: Array Palette
