SOLEIL technical solutions
for Beam Lines Control
« A control system is a sea of network objects,
every part of the control system should be a
network object whether it is a low-level, highlevel or application oriented frameworks »

Hardware devices
 The electronics group has standardized many hardware systems for
Machine and BeamLines with commercial solutions:
 Vacuum control done via PLC and Profibus -> Siemens
 Motor Control -> Galil
 All cPCI acquisition boards :
 Digital I/O boards -> ADLink
 Counting boards -> National Instruments
 Analog I/O boards -> ADLink
 Video acquisition -> National Instruments
 …
 So all the « generic » devices developed for these systems are used
on Machine and BeamLines :




Vacuum: VacuumValve, Thermocouples, IonPump …
Motor: ControlBox, GalilAxis, GalilSlit…
CPCI acquisition board: ImgGrabber, SingleShotDIO, EventCounting…
…
 For non standardized systems such as detectors:

 Specific devices were developed.

Equipment and sub system devices
 For beamline systems such as :
 Mirrors
 Monochromators
 Diffractometers
 Some libraries were developed based on a long term specification work
done with beamline scientists :
 MonochromatorLib
 HKL lib…
 The devices are then developed on top of these libraries:
 If possible a generic device is developed: (GenericBender,
DiffractometerEulerian4C, …)
 If not possible: a device per beamline (MonochromatorDiffabs,
MonochromatorSamba, …)
 These libraries allow:
 Reduced the device development cycle (One week per Monochromator)
 Standardized optics devices control software interface

Process And Calculation devices
 As for other devices, we tried to standardize:
 ScanServer
 DataFitter
 TangoParser
 Java Generic Devices (statecomposers,
attributelistewriters, ..)
 BeamImgAnalyzer
 Archiving devices
 DataRecorder: data storage in Nexus Format (see next
presentation of S.Poirier)
…

Supervision: GlobalScreen
 As for the Machine, we provide
the GlobalScreen IDE which
allows non software developers
to realize their own Supervision
Applications:
 A work group in Experiment
Division has defined « graphical
views » for common equipments:
 Front End
 Mirror, Monochromator, …
 Each beamline has
developed its own
application using these elementary
components.

Process Driving: Salsa
 Salsa is the application on top of the Scan Server
device to realize:
 TimeScan
 1D Scan
 2D Scan
 Deployed and will
be used on all
Beamlines
 Used also on the
Machine

Process Driving: Passerelle
PASSERELLE
allow to
graphically
design
sequences by drag
and drop
and execute them
 PASSERELLE is provided by a company called ISENCIA
 That realized process driving for industrial companies.
 PASSERELLE is based on an environment for scientific
modelisation and simulation: PTOLEMY (developed by the
Berkeley University)

Principle
 We connect « boxes » and « wires »:
 The « boxes » are called ACTORS, they execute an action.
 The « wires » are called MESSAGES, they transfer data.
 The graphic language for editing sequences provided all
functionnalities to build complex logics:




Loops
Comparison
Error management
Parameterization
 Every actor is configurable with parameters.
 Our team is developing actors that control Tango devices.

Passerelle users’ environments: IDE
IDE: development, configuration, execution,
debugging:

14
Passerelle users’ environments: Generic HMI
 Graphical panel on top of any Passerelle sequence.
 Possibility for users to customize the configuration panel :
 Selection of the visible parameters.
 Parameters’ labels.
 Panels organization.
 Allow to launch it,
and visualize
User logs

20th March 2007 – Tango Meeting – G.Abeillé
15
Passerelle users’ environments: Specific HMI
 Principle:
 Some beamlines were not happy with the generic HMI
 For complex sequences the parameterization with the generic HMI is too
complicated.
 Allow end users to do acquisition on the beamline without any
knowledge about Tango or Passerelle
 These GUI appear to be « the beamline acquisition application »
 But it is only possible for fixed range of sequences:
 Because sequences modification may imply the evolution of the
configuration interface.
 For the moment, these Specific HMI are developed by us
(Java):
 But our aim is to provide « something » that could be
developed/customized by beamline teams (as for GlobalScreen)

Passerelle users’ environments: Specific HMI
 At the moment, 4 Specific HMI have been developed:

17
Passerelle users’ environments:
Bossa Nova, a prototype
 An application that allows to
create « a batch »
of many passerelle
sequences:
A table where
the user gives
the list of
sequences to
execute
The Passerelle
Generic HMI to edit
the parameters of each
sequence of the table

Conclusion
 A big effort has been made by both the electronics and computing
teams to standardize as much as possible:
 We spend many time in specifications meetings with our client before
starting coding something.
 We have adopt the iterative cycle for development of user tools:
 We now provide versions devices/applications in cycle of 1-3 weeks so that
client can test it and precise its specifications.
 There is still many work to do for us:
 Quality, e.g.:
 many documentation still to been done
 It is not clear what version of devices are deployed.
 Integration: we provide many graphical tools the users see as small bricks.
At the end, it should be integrated in one/few applications.
 Because everything is done in Java, there are no technical difficulties to do it.
 The problem is that the clients do not have a clear vision of how they want to
have !!
