2. How to check a particular PV
is connected,
in sequencer?
Use pvConnected [1].
3. How to run multiple ioc(it
may be soft or hard, having sequencer program ) on a single
linux machine(Fedora
19).
I am getting warning when running
multiple
IOC machine. similar to ...
cas warning : configure TCP port was
unavailable
cas warning : using dynamically assigned TCP port 56892
cas warning : but now two or more severs share the same UDP
port
cas warning : Depending on your IP kernel this server may not
be
cas warning : reachable with UDP unicast (a host's IP in
EPICS_CA_ADDR_LIST)
I found some mail trail online
but could
not get straight way. I also tried with putting firewall off.
These are the warnings that you get when you run multiple IOCs on
one machine.
They are warnings (and not errors), and the only way to avoid them
would be running only one IOC on a machine.
(Details are in the CA Reference Manual [2].)
4. How to monitor a passive
record even
it has same value after update.(as camonitor do not
show/reflected same
value update in pv ).
This depends on the record type. For analog records, set MDEL to -1
to get a monitor update for each processing.
(This is described in the Record Reference Manual [3].)
Please read the documentation that is available at the EPICS web
site. [4]
Attending a training can also get you up to speed quickly. (Usually
two-day trainings are held at the EPICS Collaboration Meetings. [5])
