The sequence record allows you to add delays for each step, and it has more links than the fanout record. You would probably add a delay before Link 0 and "0" delay for the rest.

I checked that the PROC field does process the record, and it does.  I mistyped the fanout record name at startup, which is why those were not propagating, but they are now and I do not have an issue with undefined records.  My problem is now that the records are not propagating to the hardware.  If I process an individual record, the value propagates, but not when I run the fanout record.  Is there a way to slow down the fanout processing, or is this a job for the sequencer?

 

Thank you,

 

Iain.

Hi Iain,

 

You could try writing to the PROC field to verify that processing the record clears the UDF field.  If it does, then you could set the TPRO field in the database, and reboot, to check that the fanout record is actually processing the record.

Subject: Autosave PVs showing up as INVALID(UDF_ALARM)

 

I am using autosave in an IOC.  Several PVs show up as INVALID(UDF_ALARM).  Autosave is set to restore in pass 1, and the PVs appear to be in the autosave .sav files.  In addition, I use a series of fanout records to try to force processing of the PVs, although I again get the Undefined status.  Are there any items I can check to try to resolve this?

 

Thank you,
