[Dsg-rich] Found typo in cRIO client preventing air tank PPM from writing to EPICS

[Tyler Lemon]

Hello, 

The update of the N2 Vol cRIO EPICS client is complete to fix the typo preventing the water concentration in the air-cooling buffer tank from writing to EPICS is complete. 

The water concentration PV is "B_DET_RICH_INTLK_AIR_H2O_PPM1". An indicator will be added to the RICH EPICS screens to display the value. 

The cRIO is back online and running as normal. Any alarms after this point should be investigated as an issue. 

Best regards, 
Tyler

Hello, 

During the deployment of the RICH EPICS client correction, there was a false high nitrogen flow alarm caused by incorrect interlock limits loading during reboot of cRIO. 

Nitrogen flow did not changed from before or after reboot. 

There may be more false alarms from the loading of incorrect interlock limits during the checks and final reboot to fix fix the water concentration PV. 

Best regards, 
Tyler

Hello, 

I looked at the EPICS client this morning for RICH N2 cRIO that is responsible for publishing the air-cooling buffer tank's water concentration to EPICS and found a typo for the PV name on the cRIO. 

Correcting the typo should allow the water concentration to be written to EPICS. 

Once the LabVIEW is corrected, thecRIO will need to be rebooted to deploy the changes. 

RICH HV/LV is off, but if there is any reason the cRIO should not be rebooted without using an override switch, please let us know. 

Best regards, 
Tyler
