3. G. Maron, Agata Week, Orsay, January 2007 3 Run Control Main Tasks Access to the Agata data acquisition system (login) Configure the daq –Select the partition to run (i.e. a gts partition, enable/disable ancillary, etc.) –Run multiple partition (e.g. calibration mode) Synchronize other sub-system (e.g. slow control, trigger, ancillary, etc.) to be configured Control the overall system (e.g. start, stop, etc.) Handle all the information (e.g. generic log) and error/state messages –Show (e.g. alarms) –Archive (history) –Handle the error in some automatic way (e.g. expert system) to help to fix malfunctioning Monitor the DAQ (e.g. data rate, error rate, etc) Provide access to the GUIs Provide tools to help the cooperation for people in shift (e.g. logbook, chat, videoconference, etc.)

Slow Control main tasks –Store (DB) hardware configurations –Load a given configuration –Monitor the component –Handle error/alarm events and pass them to the Run Control

Controls, Errors and Monitors: the “hooks” of the Sub-Systems

7. G. Maron, Agata Week, Orsay, January 2007 7 “Hooks” definition General –The sub-systems hooks should be an interface as much as possible homogeneous between the different systems. This help the task of the top IM. –Some effort should be put in this phase to define these interfaces Hooks –Controls Send commands and receives back a status Set and get parameters –Errors Send log information and errors. Errors are sent asynchronously –Monitor A publish/subscribe mechanism should be used to select the variables to monitor

8. G. Maron, Agata Week, Orsay, January 2007 8 Monitor Hooks Daq application e.g. Data Readout V1 V2 V3 1. Publish the variables that can be published (defined at the code level of the application) 2. Brows the variables you want to monitor (e.g. Data rate) 3. Get the selected variables (e.g. Data rate every 2 seconds) e.g. V1 = Data Rate V2 = Error Rate V3 = Buffer Occupancy

9. G. Maron, Agata Week, Orsay, January 2007 9 Every DAQ node should have the monitor hooks Monitor Collector nodes should be defined in order to have summary views of the sub-system of part of it Daq application V1 V2 V3 Daq application V1 V2 V3 Daq application V1 V2 V3 Daq application V1 V2 V3 Monitor Collector V4 V5 V6 Monitor Subscribers Monitor Subscribers
