Experimental Physics and Industrial Control System
Pete:
here is a tarball to test.
you may need to edit configure/RELEASE file if
EPICS_BASE and SNCSEQ on your mashine are different from
EPICS_BASE=/usr/local/epics/base
SNCSEQ=/usr/local/epics/snc
Also, for this test you will need a couple EPICS
string PVs in the other IOC on the local network.
In my case I used
23d:XY:my2:StrCmd
23d:XY:my2:StrRsp in the VxWorks IOC with PMAC
controller.
We observed weird behaviour of the SNL test program
with EPICS releases 3.14.9 and 3.14.10 and with SNL releases 2.0.11 and
2.0.12.
To run the test:
make
cd iocBoot/my_ioc
./st.cmd
seq snc_my_test,"mydev=<PV
prefix>"
Regards,
Oleg
