Admitting to your problems is how you fix them. lol. Once I got the ao to scan correctly, problem solved. Power supply is updating properly now. :)

All,
I'm using a subroutine record to calculate a drive voltage. The output of the subroutine is tied to the DOL of an ao record and used closed_loop as normal. The UDF of the ao is never getting cleared after startup. If I force UDF to 0 the ao processes and sends the correct stream to the power supply and changes the voltage. Any ideas on why UDF is not clearing allowing the ao to process as the drive voltage updates? I am missing something else?


Thanks,

Wesley
