Wesley, 

Under the Detector/FT menu in the clas12_menu.opi file, there needs to be GUI's for the FT Interlock system. 


The CSS test GUI we made to test the FT EPICS interface could be used, however it does not look like the other existing CLAS12 GUI's (compact, dark colored background, etc.). 


In the new SVT svtOverview.opi, a section for hard interlocks has been added. GUI's similar to this is needed for the FT. 


A softIOC is not needed since the FT Interlock cRio is configured as an EPICS server (IOC). 


Regarding the alarm handler, there will be a few signals for the handler to report the status of the system. We'll list them later after talking to the FT group that is coming in May. 


DSG will be implementing a similar new Hardware Interlock System for the RICH in the upcoming few months. We'll also be upgrading the existing SVT Hardware Interlock System to include the EPICS interface that will use the GUI's that have been started already. I'll mention these projects in the next slow controls meeting.

Peter, 

It's not clear what you are asking. It looks like you are pretty far along. The older version of cs-studio you are using may have compatibility issues with the latest version we are testing. But that's easy to try. 

The documentation and block diagram you doesn't really answer these things: 

Do you need a softIOC to write these PVs too or did you make one? 
Do you need the alarm handler setup? 

You still have a standing invitation to the slow controls meetings. But as Brian/George did for gas systems, you can keep us in the loop without attending.

Hello Wesley, 

The Hall B FT group needs a CSS GUI for the FT Hardware Interlock System. This GUI would be integrated into the other FT EPICS screens. 

The FT Hardware Interlock System is an independent backup system which can disable the LV, HV, and FT chiller. The system can be monitored and trip thresholds adjusted via Labview and/or an EPICS GUI. 


DSG has completed the initial programming on the cRio for the EPICS interface. Located in the EEL building and configured as an EPICS server, the PV signals are now available via the Hall B .86 subnet. The EPICS interface has been tested via a CSS test GUI. 


Detailed information on the system configuration, hardware, EPICS PV signal names, CSS test screen .OPI file, and LabVIEW interface can be found on the FT Hardware Interlock System website here:
