Instrument Control System Seminar, 20 th -24 th October 2014 ESPRESSO PLC TwinCAT SW  PLC projects  MAIN PLC project  Standard devices libraries Libraries provided by ESO ( Common_TC3.lib, Motor_TC3.lib, Lamp_TC3.lib, IODev_TC3, LDLS_TC3...)  Special devices libraries Provided by us ( Shutter.lib )  Variables stored by type: Enumerated Structure  Visualizations Control template

Instrument Control System Seminar, 20 th -24 th October 2014 ESPRESSO PLC TwinCAT SW  HW configuration  Motors axis parameters Default velocity, acceleration, jerk,...

Instrument Control System Seminar, 20 th -24 th October 2014 ESPRESSO TwinCAT libraries examples  ESO Motor library Motor PLC configuration panel Motor PLC control panel

Instrument Control System Seminar, 20 th -24 th October 2014 ESPRESSO TwinCAT libraries examples Shutter PLC control panel  Shutter library  PLC: interface between NGC and 3 shutters Open/Close CMD from NGC Configuration set from WS Control panel for maintenance Shutter control system

Instrument Control System Seminar, 20 th -24 th October 2014 TwinCAT - impressions  Important to have TwinCAT and Visual Studio versions aligned between users  Useful to store parameters in NOVRAM memory  TwinCAT 3 in Visual Studio may give problems sometimes with the visualizations (youth problems?)  Care with libraries managment and libraries dependencies

Instrument Control System Seminar, 20 th -24 th October 2014 Conclusions and suggestions for the future  We had very constructive suggestions and help from ESO for the development and testing of the ESPRESSO PLC projects!  TwinCAT 3 ESO projects tutorial could be useful for the future  Project files name policy  Twincat project folder organization (template)  Software versioning and revision control system: SVN?  SVN tutorial ?  Right place to archive the PLC code?
