4. Guidelines and concepts
Use experience gained at FLASH
FLASH is a small version of the XFEL
Developed and test at FLASH (partly PETRA)
be ready when XFEL (construction) gets ready
Develop generic recipes and frameworks
ensure portability (FLASH  XFEL)
Implement on middle layer where possible
have common interfaces & exception handling
reduce load on front ends
to e.g. avoid “wildly running FBs”

13. Automation: Sequencer
Sequencer done by P. Castro and J. Maass
In standard operation at PETRA and FLASH
Fits all needs, except …
… need extension to allow cascading of sequences
some architectural rework needed (implement as service)
Accelerator Controls Conceptual Design Review, 14. Dec. 2009, Raimund Kammering - MCS4

14. Automation: FSM, DOOCS server
FSM designer
Can not use old (ddd based)
create new one in jddd?
create FSM C++ library?
we need scenarios/use cases!
DOOCS server
mainly for hardware near automation
mostly used on front-end
… but can also be used on middle layer

16. Measured performance and gained experience meets requirements
Summary/conclusions
Existing frameworks are sufficient for solving the expected high level software tasks
Measured performance and gained experience meets requirements
Frameworks cover full range of expected applications
Test and implementations at FLASH need to be continued
A graphical FSM designer or library might be helpful
Needed tools lists and use cases need to be completed
monitors and actuators need to be specified
algorithms and data exchange must be worked out
