We have an EPCIS server (ioc) running on our raspberry (ext-027377). It talks to our MesyTec modules (MSCF shapers, MHV4 high-voltages).
In principal it should be running all the time, but here is the manual how to check/start it:

-login on GSI-linux using <litv-exp> user
-type in console: e121pi (alias for: 'ssh -X litv-exp@ext-027377.gsi.de')
-open the "mrcc" screen session: screen -x mrcc
-if the ioc is running you will see here terminal outputs like:

Quote:
cbLow: Active ringpi:mrcc:mhv2:getRcStatus
cbLow: Active ringpi:mrcc:mhv2:getCurrent1

-if this is not the case, you have to restart the ioc:
- <Ctrl>+c to end any running ioc (if it has errors)
- the command to start the ioc: e121_ioc (alias for '/home/litv-exp/epics/mrcc_ioc/bin/linux-arm/mrcc /home/litv-exp/epics/mrcc_ioc/iocBoot/iocmrcc/start_ringpi.cmd')
- now the terminal outputs should be as quoted above (errors show up in red)

- finally <Ctrl>+a d to exit the screen session
  5   Fri Dec 7 11:39:41 2018 Jan GloriusSlowControlGUI for remote control of MSCF+MHV4
We have a GUI for remote controlling our MesyTec modules MSCF16 and MHV4 for E121 experiment.

Here is the instructions to run it:

1. login to GSI-linux using <litv-exp> user
2. get the EPICS environment by typing in terminal: epicsfind
3. type in terminal: GUIe121 (alias for 'medm -x /u/litv-exp/E121/medm/e121.adl')

if you get the message: 'medm: command not found' you didn't load the EPICS environment (2.)

The GUI is more or less self-explaining.
Be sure to follow this procedure when changing a value (e.g. threshold for MSCF):

1. click on small text-panel with value
2. leave mouse pointer inside panel
3. change value by typing
4. press enter

We have a GUI for remote controlling our MesyTec modules MSCF16 and MHV4 for E121 experiment.

Here is the instructions to run it:

1. login to GSI-linux using <litv-exp> user
litv-exp@astrum1:~$ ssh -X litv-exp@lxg1254.gsi.de

2. get the EPICS environment by typing in terminal: epicsfind
litv-exp@lxg1254:~$ epicsfind
Found nice EPICS in /u/litv-exp/epics/opt_x86_64-linux-gnu_4.9.2.


3. type in terminal: GUIe121 (alias for 'medm -x /u/litv-exp/E121/medm/e121.adl')

Sergey and Yuri are tuning Tl beam. The particle number in ers is about 1e4. I(SIS)=5e8

some events on MWPC can be seen !

The Tl fragments are being stacked (almost ~20 staacks) and tried to store nicely in ESR.
The plan is to see the number of contaminants on the inner detector (CsISiPHOS) after the gas jet is on (Ar gas jet) and minimise this number for different FRS settings !!

P.S. Prayers have magical powers :) :)
