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)
