[Dsg-rich] [New Logentry] RICH hardware interlock program updated, cRIOs rebooted.

[Tyler Lemon]

Hello, 

The new PVs for the differential pressure transducers have been added to MYA for archiving. 

Their PVs are: 
N2/EP differential pressure - B_DET_RICH_INTLK_N2-EP_DIFF_PR 
N2/atm differential pressure - B_DET_RICH_INTLK_N2-ATM_DIFF_PR 

Best regards, 
Tyler

RICH hardware interlock program updated, cRIOs rebooted.

The N2 cRIO's LabVIEW program has been updated to read two differential pressure transducers. 

The two pressure transducers were installed and connected to the cRIO on March 12, 2018. One pressure transducer measures the pressure differential between RICH's N2 volume and EP. The second measures the pressure differential between RICH's N2 volume and atmosphere. 

A request has been made to Nathan to add the signals to RICH's IOC. The PV names requested are below: 
N2/EP differential pressure - B_DET_RICH_INTLK_N2-EP_DIFF_PR 
N2/atm differential pressure - B_DET_RICH_INTLK_N2-ATM_DIFF_PR 

If the PV names end up changing, this entry will be updated with the correct PV names. 

The code to read the RICH air-cooling tank's water concentration in PPM through EPICS was also corrected. This signal has the PV: B_DET_RICH_INTLK_AIR_H20_PPM1. 

No changes were made to the EP cRIO interlock program, but the cRIO was rebooted 

Both cRIOs are back online. LV has been turned back on at the direction of Marco Contalbrigo.
