ELT French Instrument control Software expert group

Two groups of participants: From October 24th - 26th or from October 29th - 31st

EFISOFT organises a formation with Beckhoff France in Villebon sur Yvette. This formation will regroup french actors from several projects (HARMONY, MICADO, MAORY, MOSAIC, HIRES) within the EFISOFT structure.

We have a preliminary agenda created with Beckhoff:

Day 1

  • Presentation of the Beckhoff Architecture
  • Mount/ Dismount / maintenance of PCs and controlers
  • TwinCAT software installation
  • EtherCAT network overview
  • Deployment of EtherCat network under TwinCAT2/TwinCAT3.
  • Diagnostic level details.
  • Peripheric scan (input/output drives)
  • Configuration of device architecture
  • Automate coding within IEC 61131-3 norm :
    • Variable creation
    • Link to physical input and output
    • Overview of coding tools (structures, block functions ...)
    • Usage of debug tools (stop, crossed links, ...)
    • Soft loading, creation of Bootproject
    • Example of code
  • Diagnostic of Hardware and software

Day 2

  • Remote connection from PC
  • Soft transfert between PLC and PC
  • Fundamantal notion on RunTimeNC-PTP
  • NC task axes function (absolute, relative movements, synchronization)
  • Motors and variators setting
  • NC task setting
  • TC-MC2 library and use of bloc functions applied of axes movements
  • Scope view
  • Diagnostic and maintenance of motion hardware

Day 3

  • Global TwinCAT PLC HMI overview
  • Project creation
  • Deployment of IHM
  • Use of Scope view tools
  • Experimental exercise with PLC and IHM (reinforcement of acquired knowledge of day 1)
  • Training on machine maintenance / looking for breakdown (reinforcement of acquired knowledge of day 1)
  • Maintenance of industrial PC : saving data, performance analyse, deployment
  • Questions, and other specific point not covered

European Southern Observatory

Instrument Control Systems Seminar - 11.11 - 14.11.2019


The purpose of the seminar is to provide the instrument developers with an overview of the ELT hardware and software development platform, which will be used for implementing the control of the instruments. It is also an opportunity to present and explain the framework solutions being developed by ESO in the area of instrument control and get immediate feedback from the participants.

Who might be interested in attending the seminar:

  • Instrument control software developers.
  • Control engineers.
  • Electronics engineers.
  • System engineers and project managers who need an overview of the technologies in use.
  • Pipeline developers/developers of data reduction software.

Considering the number of speakers and different subjects that will be covered, the level of detail of each talk may vary.

The ELT is still in an early development phase and therefore not complete and subject to changes and updates for what concerns technology and some design choices. Nevertheless we believe that makes sense to have the seminar now for making the developers acquainted with the existing solutions and the ELT plans for the coming years.


The participants will have themselves to care of their travel arrangements and accommodation.

The following hotels, located in Garching, provide easy access to ESO:

For other logistical matters, please contact Svea Teupke (This email address is being protected from spambots. You need JavaScript enabled to view it.) or Jens Knudstrup (This email address is being protected from spambots. You need JavaScript enabled to view it.).

We have defined an upper ceiling of 80 participants that can attend the seminar.


The preliminary agenda can be accessed here.

Information about the Pipeline Seminar on the 15.11.2019, can be accessed here.

efi|soft is a french national group of experts dedicated to the control command software development of all ELT instruments. efi|soft covers :

  • control and supervision of technical and scientific detection devices
  • control and supervision of instruments functionnalities
  • coordination af all instruments subsystems, e.g. the telescope or the adaptive optics system.
