This should work and does in all of my tests, and on many production
systems.
Do you get any error messages?
Could it be a problem with access security i.e. the other IOC cannot
access the PV at all (no read access)?
If these hints don't get you any further, I am willing to investigate
this in more depth, but for that more information is needed:
* the exact versions of EPICS base and sequencer that you are using
* under which OS the IOCs run
* a complete log of the build and the IOC startup process for both IOCs
(please add them as attachment, not in the text part of the mail);
It would be helpful if you could run seqChanShow on the IOC that
contains the sequencer program, so we can see whether the PV is
connected at all.
Cheers
