Getting started

In order to start a session of the NP04 Run Control follow this step-by-step guide:
  1. Log into np04rcui using the personal CERN credentials ( ssh -XC <username> )
  2. Execute the alias RC for the Run Control multi-partition panel.
  3. Enter your CERN credentials when prompted.

Legacy mode: in order to operate the Run Control locally from the np04-srv-024:

  1. Log into np04-srv-024 using the np04daq account ( ssh -XC )
  2. Execute the alias RC_024 (note the different alias) for the Run Control multi-partition panel.
  3. Enter your CERN credentials when prompted.

You now have the NP04 Run Control GUI available for operation.

In order to start a run follow this steps (clicking on the ProcessManager button you will open the DAQInterface real-time log):

  1. Identify an available Partition (all nodes are grayed out) browsing the tab menu.
  2. Click on the (open) lock icon next to the Partition top node and select "Take" to get the exclusive command of the Partition.
  3. Before booting the system, click on the BoardReaders node in the left tree viewer. This will open the BoardReaders page, allowing you to include or exclude APAs and components.
  4. Repeat the previous point with the EventBuilders node in order to define your data acquisition system.
  5. From the top Partition node, select the artdaq folder from which to execute the acquisition system.
  6. After defining the desired system, click on the Partition state button (now displaying UNKNOWN state). You can now click on BOOT
  7. When the included processes are BOOTED, you can now CONFIGURE the processes. The CONFIGURE command requires the user to select the desired configuration and Run type from the activated drop-down menu. After the selection, the configuration files are applied to the processes.
  8. Select START from the top node to start a new run. Run number will be automatically fetched.
  9. The system is now RUNNING
  10. The previous step enables the optional "Trigger options" panel. Select a trigger rate and Enable the triggers.
  11. The system transitions to RUNNING with the InhibitMaster inhibiting all trigger. You need to click on the "Allow trigger" button in order to get triggers flowing.
  12. In order to stop a run, select STOP from the top node.
  13. After stopping the run, use SHUTDOWN to terminate and kill the processes. The system will then transition to UNKNOWN state.

After operation and/or before closing the RC panel, remember to Log out (right-click on the top-right yellow key) or release the tree from the top node lock.

In case of problems consult the Troubleshooting section.
