Experimental Physics and Industrial Control System
Hi,
Two questions:
1. If a channel is connected or reconnects, and a call to
ca_create_subscription succeeds or has previously succeeded, is there
anything else that could go wrong on the ioc side that might cause the
channel not to be monitored (other than the channel disconnecting)? And if
so, is there a way to tell from the client side? Do I have to wait for the
event handler to be called before I can trust that everything is working?
2. How do you usually deal with setting a pv invalid if the data is being
put to it from an external program (ie, not device support) and that
program fails? Do you write device support for the ioc hosting the pv, and
use it to get the value and a status update from the program? Is there a
more preferred method?
Thank you,
Patrick
