[Dsg-halla_gem] GEM PV database file

[Marc Mcmullen]

Hi Steve,

I did a “caget” on a couple of the PVs on the opsl00 server and the Raspberry Pi. The reply is invalid channel name.

I did ping adaqsc from both the opsl00 server and the RP. I can see it from both.

I also did a test using PVs running on a soft IOC on the Pi and was able to verify those on opsl00.

Marc:

I setup the records.  I attached the .db file that is running on adaqsc.

I made the SCAN for the records “Passive”.  I think that is right for how you are using the records.  And I made the device type of every record “Soft Channel”.

Let me know if WEDM/opsl00 can see these records.  I didn’t check.

That will be fine, can you use HAGEM:BB? So we can distinguish between the big bite and super big bite.

Marc:

I will set these up on adaqsc.

I assume that some other thing will be pushing the values to the signals.

Would it be OK to replace “tedf” in the signal names with “HAGEM”?

Hi Steve,

I believe the GEM group will want to start monitoring the BigBite GEM gas flow remotely. I think you said you could add the database file for the PVs to an IOC for Hall A. These PVs will be displayed by a WEDM page on accelerators opsl00 server. I have attached a .txt file which we used for the .db on the IOC when the system was located in the TEDF, but that was on a different subnet which is not available in Hall A.

Regards,
Marc
