Setting up and Running an Epics Input/Output Controller

Running the Epics IOC

The above installation will build all the epics modules, including the Xspress 3 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 Xspress 3 IOC

File	Description
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 XSPRESS 3 IOC
bin/start_ioc	python script to run the Xspress3 using procServ
bin/run_xrfcontrol.py	python script to view and control the Xspress 3
bin/run_medm.sh	bash script to launch medm for your Xspress 3

After building you can configure an Xspress 3 IOC, starting with one of the defaults in the ioc directory:

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

Note

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 xspress 3 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:

File	Description
/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 Xspress 3 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
