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

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
