[Dsg-hallb_magnets] Magnet cRIO status in EPICS

Hi Tyler,

These indicators come from the PLC.  This is for checking communication from cRIO to PLC.  Probably the tag names just need to be updated in the Solenoid Logic to match the EPICs PV

Best Regards,

Nick

Hello Wesley, 

On the EPICS screens for the Torus and Solenoid interlock status, there are indicators for "cRIO FastDAQ Comm" and "cRIO Comm". I've noticed that while the Solenoid Fast-Daq cRIO and Solenoid LV cRIO are operational, both Solenoid cRIO Comm indicators are red. 

How are these communication checks determined? Is there data that need to be sent to EPICS from the cRIOs for these indicators? 

Best regards, 
Tyler
