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
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
the next runs a startup script on the
NFS mount that does other NFS
mounts, and a third that launches the
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
- 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?
