[Dsg-halla_gem] [EXTERNAL] SBS Gas panel web page not working

Tue Nov 16 18:11:49 EST 2021

John,
I noticed it just a bit ago. I’m checking on the Raspberry pi now, I can’t connect to the muxes. It may be an issue with the bench supply.

Marc,

We had a power issue today and the computer for gas monitoring shut off. Since then we haven't been able to see a heartbeat on the gas flow monitor.

Please advise,

John

On the gas panel monitor in EEL 125 there seems to be an issue. The values do not update regardless if I refresh/reload the page or if I manually change flow values.

Please advise,

John

Hi Anu,

I moved the monitoring file back to the original directory. Here is the link:

Anu,

That explains the issue. I moved the wrong page to off-line. I’ll correct it.

Hi Marc,

Thanks for the link. We can see the readback fine now. However, there is a discrepancy between the channel numbers we read in this link vs the channel numbers we read on the screen in front of the gas panel.
On the screen in front of the gas panel, channel numbers start with 9 in agreement with the flow meter numbering, whereas in this link the channel numbers start with 1.

Could you please correct that if possible?

Best,
Anu

Thanks for sending that Marc. The first link that Anu sent doesn't work but the one you sent does. I guess it got changed/updated at some point?

Thanks for the help and sending that over.

Hi Anu,

I just checked the SBS monitoring page. It is still working. But I did clean up all my test files from the directory this morning.

The link is https://epicsweb.jlab.org/wedm/screen?edl=%2fa%2fopsuser%2fmccops%2fedm%2fdsg%2fSBS_GEM_Flow_48.edl

Holly,

I wasn't referring to the BB gas panel.

There is a similar one that we use in EEL now for SBS GEMs.

Hi Marc,

The following link you provided us with to monitor SBS gas panel flow rates did not work starting today morning
https://epicsweb.jlab.org/wedm/screen?edl=%2fa%2fopsuser%2fmccops%2fedm%2fdsg%2fSBS_GEM_flow_press.edl

Could you please take a look into it when you get a chance?
Thanks!
