Freiburg, May 2011 EST Design Study. End of Phase-III Meeting 2 Instrument Control Software Overview The instruments are designed and constructed to be used simultaneously and synchronized. There will be also a deep interaction among the ICS and some external sub- system developed by other sub-WPs

Freiburg, May 2011 EST Design Study. End of Phase-III Meeting 3 EST ICS architecture Two options are available to send a command to ICS. In the former case an already defined configuration, i.e., list of commands and parameters, can be send to the ICS through the sequencer. In the latter case a generic user can select a configuration by the GUI. Moreover, the user can download a complete configuration and can use the GUI to modify some parameters or part of the setup.
