Hi All,
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.
Cheers,
- Bruce

Dear Ethan,
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 !
regards,
Laurent.

Hello all,
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?
Thank you,
Ethan
