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)

17. Padova 16 Nov 2004Marina Passaseo17 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.

18. Padova 16 Nov 2004Marina Passaseo18 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)
