GPIB Local Slow Control (LSC) Server Information

What can the GPIB LSC do?

• Able to control most GPIB boards.
  
• Currently able to control:
• Trigger Conditioner Boards
• Trigger Logic Board
• Front End Boards
• Can be easily extended to control:
• RTF (Receiver/Trigger/Filter) Board



How does the GPIB LSC do this?

• Receives change of run state commands from Run Control.
• The change of run state commands includes pointers to configuration files.
• The configuration files are configuration manager generated.
• Here are a couple sample configuration files:
• Here is a sample trigger conditioner board configuration file.
• Here is a sample trigger logic board configuration file.
• Here is a sample front end board configuration script (this calls individual configuration files).
• Here is a sample front end board configuration file.


• Verifies that the change of run state command with the InterLock Manager.



• Writes the appropriate commands to the GPIB boards.
• Have successfully changed settings on the Trigger Conditioner and Trigger Logic boards across the UCSB network.
• Expect to verify that settings can be remotely changed on the Front End Board before the DAQ review.



What if an error occurs?

• Many failures are reported to the Run Control Server
• For example, attempting to write an invalid command to a GPIB board would return a failure to the Run Control Server.
• As we learn the causes for errors, we can make the GPIB LSC correct its own errors.
• We should start to implement this in the near future.
• Errors will be sent to the Error Manager.
• Error Bridge to send the errors has already been implemented.
• However, the GPIB LSC does not yet utilize the Error Bridge to send errors to the Error Manager.



Where can I find documentation on the actual GPIB boards?

• Trigger Conditioner board design and diagnostics information is available.
• Trigger Logic board design and diagnostics information is available.
• RTF (Receiver/Trigger/Filter) board documentation can be found here.
• Front End board documentation can be found here.
• Other GPIB documentation can be found here.
