[Dsg-rich] [New Logentry] RICH Hardware Interlock program updated

[Tyler Lemon]

Hello, 

The RICH hardware interlock screen on clascss has been updated. Screenshots of all tabs are attached. 

There are now four tabs on the screen: 
1.) interlock status and signal monitoring - same as previous version 
2.) threshold and enable control settings - all data for each sensor on same line as requested 
3.) summary of interlocks - same as previous version 
4.) nitrogen volume - front projection of RICH showing nitrogen volume sensors. 

Once sensor locations for the electronic panel are finalized, a graphic showing those sensor locations on the electronic panel will be added. 

At the top of the screen, there are two indicators for the override switch on the cRIO chassis. They currently show "OVERRIDE OFF" and are disconnected. These indicators will be fixed in the upcoming days once their PV is added to the EPICS server. 

Best regards, 
Tyler

Hello Tyler, 

Could you please edit the user GUI in such a way that we have 
all parameters for each sensor in one line. 
For example 
Name : current value : Low Limit : High Limit : Interlock Status : Enable/Disabl. : Interlock Errors 
For a moment all these parameters are on two pages in different columns. 

The summary of interlocks is OK. 

We will appreciate if you can do it. 
Thank you, 
Valery

RICH Hardware Interlock program updated 


Lognumber 3496634 . Submitted by tlemon on Mon, 11/27/2017 - 16:35. Logbooks: 	RICH 


The LabVIEW program for the RICH hardware interlocks has been updated. 

The updated program (interlock program version 23) has been deployed to the cRIO and set as its start-up application. Changes made in the update are listed below. 

1.) Added subVI containing look-up table for all humidity sensor calibrations. Before, all humidity sensors had their own unique subVI with their calibration constants. Look-up table subVI puts all calibrations constants in the same subVI for easy access and changes. NOTE : all calibration constants in new subVI are the same as before the update. Only coding of how program obtains constants for sensors has changed. 

2.) Debugged "threshold control" control on LabVIEW UI. Previously, program was stuck in "EPICS Threshold Control" mode and could not be changed on LabVIEW UI Expert tab. Found part of LabVIEW code causing issue and after correction, threshold control mode can now be toggled between "EPICS Threshold Control" mode and "UI Threshold Control" mode on the LabVIEW UI Expert tab. 

3.) Enabled indicators on LabVIEW UI to show status of keyed override switches. Logic for indicator was already in program, but commented out as keyed switch hardware had not yet been installed. After enabling indicator, it was verified that the indicator correctly reads the status of the override switch.
