[Dsg-hallb_magnets] DBX Cryocon Watchdog PV

[Brian Eng]

Probably a tag scope issue if I had to guess. We can worry about this some other time as it isn't critical.

It's not happy with DBX_CryoCon_Watchdog, "Unknown tag or Path error".  I reverted back to the old one.

Now is a good time to do that. Bothe magnets are OFF at least until tomorrow.

Team,

Be careful and ensure that magnets are at ZERO current before employing any changes..
The impact will be very high in terms of down time to cool if that dumps..!

That change is in, just need to reboot ioctorusCryo when the time is right to pick it up.

That tag exists on the PLC but doesn't seem to be used anywhere, which makes sense why the value isn't changing in CSS.

The tag should be DBX_CryoCon_Watchdog on 96.17

Ah, my copy/paste had some odd character in it.  The tag is "CryoCon_Watchdog" on 129.57.96.17.

I'm not sure what it should be, that's what is on the CSS screen.

Hi Brian,

I don't see that PV being alive.  Is that the correct name for the PV?

Nathan,

Do you know which PLC tag this PV is supposed to be using?

B_TORUS:DBX:CryoCon:WatchDog

It doesn't seem to be incrementing like I'd expect it to.

Thanks
Brian
