Hi all,
We have some
problem in using sscan records with one motor as one positioner and one ADC
value from the detector.
Hardware:
VME+MVME5500+MAXv-8000
Software:
EPICS base3.14.8+MotorR6-2-2+Sscan
from synApps5_2 + (some transform records)
The problem
happens frequently when the scan is processing . When it happens:
1. All the PVs
on the EDM interface are connected, but no motor (residing in this IOC) has any
response to the new setting value of its Motor.DVAL. It seems the IOC doesn’t accept command from OPI any
more;
2. The
commands like ‘dbl’ are still working normally on the minicom console;
3. The network
between OPI and IOC is ok;
4. When
restart the IOC by typing the ‘reboot’ command on the minicom console, the
IOC can’t be recovered normally.
5. The IOC
have to be restarted by powering off and on.
We also tried
to split sscan to a PC/Linux/IOC, the problems still appear.
Any suggestion
and idea are welcomed.
