aps_machine.py #972

Closed prjemian closed 3 months ago

prjemian commented 5 months ago

Need to add 164.54.188.8 to your EPICS_CA_ADDR_LIST.

The new MEDM screens that I've seen are using 'S-DCCT:CurrentM' for storage ring current.

prjemian commented 5 months ago

On further investigation, a DCCT is a DC Current Transformer. It is not the storage ring current. It is related, though. The article states:

The change of stored current with time monitored with the DCCT provides a measure of beam lifetime.

@jkirchman replies on Teams:

If used with an oxygen-based host (my preference is 'tin'), 'xfd-display' does work properly. You can find many of the older usual screens that you may be used to. If I check one of the usual screens, I can see what operator and basic storage ring PVs are now used: 606 jkirchman@tin ~> grep chan /usr/local/iocapps/adlsys/sr/fe/SR_Status.adl | sort | uniq chan="Mt:TopUpAutoEnableC.VAL" chan="NoOfShuttersOpenA" chan="OPS:message1" chan="OPS:message2" chan="OPS:message3" chan="OPS:message4" chan="OPS:message5" chan="OPS:message6" chan="RF-ACIS:FePermit:Sect1To35IdM" chan="RF-ACIS:FePermit:Sect1To35IdM.RVAL" chan="S:ActualMode" chan="S-DCCT:CurrentM" chan="S:DesiredMode" chan="S:FillNumber" chan="S:injectingStatusBI" chan="S:IOC:timeOfDayForm1SI" chan="S:OrbitCorrection:CC" chan="SRFB:GBL:LoopStatusBI" chan="S:SRlifeTimeHrsCC"

Can test at first beamlines to start with APS-U era.

Make sure the device will connect. If not:

Is the signal still appropriate?
Check the assigned PV for any signals that do not connect.

We'd need to make sure that the beam line account can access the storage PVs through the new gateway.

Usually configured in the ~/.bash_aliases file.
