Setting up and Running an Epics Input/Output Controller

Running the Epics IOC

The above installation will build all the epics modules, including the Xspress3 application in the current folder. It will also create a ‘bin’ directory in your /home/xspress3/epics’ folder that contains scripts to set your environment and run the Xspress3 IOC:

bin/bash_profile.sh bash script to set environmental variables bin/procServ useful utility for long-running tasks like an IOC bin/medm simple, minimal Epics display manager bin/run_xspress3.sh bash script to run an XSPRESS3 IOC bin/start_ioc python script to run the Xspress3 using procServ bin/run_xrfcontrol.py python script to view and control the Xpsress3 bin/run_medm.sh bash script to launch medm for your Xspress3

After building you can configure an Xspress3 IOC, starting with one of the defaults in the

/home/xspress3/epics/xspress3/iocs/xspress3IOC/iocBoot

directory. Note that if you change the prefix or the number of detector elements used, you may need to edit several of the files in the bin/ directory to match your configuration.

Once properly configured, you should be able to run your xspress3 in a long-running procServ process with

/home/xspress3/epics/bin/start_ioc xspress3

and then view screens for your detector either using an Epics display manager like medm, caqtdm, or css/boy. Display screens for these display managers can be found in the folders

/home/xspress3/epics/adls screen files for medm /home/xspress3/epics/uis screen files for caqtm /home/xspress3/epics/opis screen files for css/boy

For example, you will be able to run MEDM for your Xspress3 with

/home/xspress3/epics/bin/run_medm.sh

You will also be able to run a dedicated XRF Control application with

/home/xspress3/epics/bin/run_xrfcontrol.py
