The embedded IOC in these iSeg CC24 controllers is indeed the
fastest and easiest route to getting EPICS control of the modules.
If you only have a few crates you can hand customize and install
the iseg_epics.db and iseg_epics.sub files and you're good to go!
At SLAC we'll be deploying 6-10 of these mpod crates each w/ several
HV modules and may add some additional crates and/or LV modules
as we commission more LCLS2 chambers.
We wanted to be able to upgrade and version control our iSeg IOCs
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 cross-compiling
the iSegHAL module on our RHEL7 build server along w/ our EPICS base
and support modules and building IOC releases there on NFS.
The CC24 uses systemd services for startup, so we disable the isegioc
and install three slac systemd services. One service does an NFS mount,
the next runs a startup script on the NFS mount that does other NFS
mounts, and a third that launches the IOC.
I've got this working on a demo unit and am looking forward to getting
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" files
- 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 it?
