15. 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

16. 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?
