Spia

Local daq

il Sector Collector vede un bit Trigout alto e da li' in poi per 40 bx (cicli) immagazzina i

dati, che conserva aspettando che il ROS li legga (cosa che il ROS fa quando riceve un

L1A)


Setup per il commissioning del settore

Hardware necessario: ROS finale Sector Collector finale

Software: DCS controllo minicrate HV LV framework versione 3 (backup: ISR setup)


Setup per il cosmic challenge

Integrazione DCS-RUN Control (FSM)

At the top level (Central DCS) a minimum number of commands are defined:

• ON : – Instructs the DCS sub-systems to be ready for data taking. This

command has a configuration parameter (Tag/Version key) recognized by the Configuration Database.

• STANDBY:– Instructs the DCS sub-systems to be in an intermediate state,

e.g. a state safer from the detector operation point of view when preparing for data taking, such that the time required for a change to ON be shorter that the transition OFF-ON.

• OFF:– Instructs the DCS sub-systems to shut down the detector at

the end of a data taking season (once a year).

• The reconfiguration of the DCS system uses the ON (or STANDBY) command with a different configuration Tag/Version key.


Subdetector DCS FSM

• ON:– The subdetector in ready for data taking

• STANDBY– The subdetector is in standby state

• OFF– The subdetector is in off state

• ERROR – The subdetector is in error state because some faulty

component was identified. In case of error the sub-system should act as following:

– Send an alarm to the alarm system– Initiate a recovery procedure– If the recovery procedure fails change state to ERROR– Compute the estimated detector inefficiency for data taking due to the

error. The inefficiency is transmitted as a parameter of the ERROR state (to be elaborated)


Minicrate FSM

• Stato 0 : OFF• Stato 1 : Inizializzazione

– Comunicazione Server OK – Verifica link ottico e rame– CCB fase di boot terminata OK– LV ok? Crates ok?– Status (minicrate mode)– Check FEB readout, Trigger board, RO board– Allineamento– Pressione
