EPICS:

/data2/epics-7.0.2.2/base-7.0.2.2/

1.  Data inherited from EPICS  and stored as tsv files:

  /data2/e1039_data/slowcontrol_data/

As of 10/23/2020 the following six groups are being saved (and also archived)

  1. Chambers: spill_XXXXXXXX_ChamHv.tsv

  2. Slow control Life scripts:  spill_XXXXXXXX_ReadSlowCont.tsv

  3. Acnet spill_XXXXXXXX_Acnet.tsv

  4. Hall enviroment  spill_XXXXXXXX_HallEnv.tsv

  5. Hodoscopes  spill_XXXXXXXXX_HodoHv.tsv

  6. Dark Photon Hodoscopes spill_XXXXXXXX_DPhodo.tsv

2. Data Stored in Archiver binary format (see below under Archiver Data Storage )

EPICS ALARMS:

Alarms are defined as deviations from thresholds provided by the system experts for each PV in a given system

The values are kept in the master spreadsheet file YYYY_MM_DD_vlist_master.ods under /data2/e1039/daq/slowcontrols/var_catalog.

...

These thresholds are checked whenever a PV is processed by the EPICS server. When this thresholds are not met , the EPICS server sends a broadcast message to each process that monitors the relevant PV.  The ALH, MEDM, and CSS are used as a monitoring processes.


Detailed ALARM information page is here.



Archiver Basics

How to start  or  stop

cd /data2/epics-7.0.2.2/base-7.0.2.2/epics-extensions/archiver_appliance

export JAVA_HOME=/data2/epics-7.0.2.2/base-7.0.2.2/epics-extensions/DownloadsShared/jdk-14.0.2/

./prelim_setupArchiver.sh stop/start

How to launch browser: 

in a terminal execute:

firefox http://localhost:17665/mgmt/ui/index.html &

That should bring up a window like this below  (takes approximately 30 seconds from a remote connection ie LANL to FNAL):

How to check the status of PV or archive a PV?

1.Type (one PV per line) the name of your PV ie T1 and T2 in the example below.

2.Click on Check Status

3.If its not being archived (the case for new PV) click on the Archive button.

4. If its already archived and you would like to inspect its history click on quick chart

4.This should bring you to the history plot. You can choose the time frame of your choice up to one year.

ARCHIVER Data storage

The short term storage differs from medium/long term locations for the following reasons (Thanks to P. Reimer for pointing this out)

  1. Primarily, if there are network problems, they may effect some links, but at least the Archiver will still be able to store whatever data EPICS has that is valid, regardless of whether or not /data2 is reachable.

  2. If there are network problems, the Archiver will still have access to recent (which we can define) data to serve to which ever clients can reach it regardless of whether or not /data2 is reachable.

  3. The Archiver will respond slightly faster as there is one network hop that it will not have to do when storing or reading data.

Short term (few hours): /home/epics/archiver/archappl/sts

Medium Term(~2 days) : /data2/e1039_data/slowcontrol_data/epics_archiver/mts

Long term: /data2/e1039_data/slowcontrol_data/epics_archiver/lts

CS-STUDIO

CS-STUDIO location

This is not EPICS based but this were it was agreed to install

Instructions Launching CS-Studio and Monitoring Detectors

See:

Data Monitoring tools for detector experts


CS-STUDIO baseline projects

/data2/e1039/daq/slowcontrols/epics/css_projects/CSS/

from the above the following projects have been created:

Hall environment:

HD.plt HH.plt HT.plt P1.plt P.plt T1.plt

Drift Chambers:

D1_V.plt D1_I.plt D2_V.plt D2_I.plt D3_V.plt D3_I.plt

Prop tubes:

P4_V.plt  and P4_i.plt


Hodoscopes:

The following sample projects have been created

LC_H3_EN_HV.plt

LC_CM.plt

X3XT_MV.plt

H3XT_DV.plt

 

Dark Photon Hodoscopes:

These is the most demanding of all detectors with 1192 PV's

We have created the following sample projects:

DP1_LT1_V.plt

DP1_LT1_CH_I.plt

and

DP1_LT1_CH1-10_I.plt which is a subset of DP1_LT1_CH_I.plt
