The embedded IOC in these iSeg CC24 controllers is indeed
fastest and easiest route to getting EPICS control of the
If you only have a few crates you can hand customize and
the iseg_epics.db and iseg_epics.sub files and you're good
At SLAC we'll be deploying 6-10 of these mpod crates each w/
HV modules and may add some additional crates and/or LV
as we commission more LCLS2 chambers.
We wanted to be able to upgrade and version control our iSeg
w/ the same tools and EPICS 7 base releases as our other
IOCs so we
found a way to do that and also add access security.
iSeg provided us w/ the arm-apalis gnu toolchain so we're
the iSegHAL module on our RHEL7 build server along w/ our
and support modules and building IOC releases there on NFS.
The CC24 uses systemd services for startup, so we disable
and install three slac systemd services. One service does
an NFS mount,
the next runs a startup script on the NFS mount that does
mounts, and a third that launches the IOC.
I've got this working on a demo unit and am looking forward
our deployment crates and HV in so I can iron out any kinks
in the scripts.
I"ve actually made a number of other changes to our demo
system in the
course of this development so I need to make sure this all
works from a
clean factory CC24.
If anyone's interested, contact me and I can provide more
details re how
to get this working.

Why don't you use directly the CC24 embedded IOC ?
I am using the EPICS "isegHAL" which is already in
the controler, so from the iCS controler WEB page in
the EPICS section you just have to :
- download the "iseg_epics.db" and "iseg_epics.sub"
- modify these files if needed
- Upload these new files
- reboot the EPICS IOC
and it should works !

I am building an IOC for an iseg CC24 Master power
supply, and need an EPICS module called 'isegHAL'. I
wasn't able to find a download for it on the
hardware support by manufacturer EPICS webpage (https://epics.anl.gov/modules/manufacturer.php#ISEG).
Would anyone know about this module or where to get
