You could put in a counter and break out of that loop after a certain
number of tries?

One way to implement a loop is which a calcout record. The CALC
expression determines whether or not to loop, and the OOPT field
specifies the condition in which the output link is executed. The
output link should a CA link, otherwise EPICS will break what looks to
it like an infinite loop.

Hello,
I would like to automate phasing of servomotors in Delta Tau.
1. Send phasing command via asyn, wait
2. If Phasing successful(bit x is set), ->DONE
3. If Phasing error(bit y is set), do 1 again.
I would like to do it in the database, and not via sequencer, because it
will give me a luxury of using a substitution file and repeating the
same for 9 motors and looks much easier. It would be interesting to see
how Delta Tau will handle several simultaneous phasing requests.
Thank you for your advice.
Oksana
