What record type are you using?

SEVR=INVALID and STAT=UDF mean that the record's value is undefined.

If you are processing an undefined output record, its value will usually

still be undefined after processing, so SEVR/STAT will remain INVALID/UDF.

If you are processing an input record using PINI=YES, usually its value

will be retrieved, so that the records get defined and the status is reset.

If your input record reads using ChannelAccess (from a remote record),

it will still be undefined, as PINI processing happens before

ChannelAccess is started.

A better way to trace processing is setting the TPRO ("trace

processing") field of your record to "1". This will make it print a line

on the console when it processes.

Hi,

I have a problem of understanding the initialization of databaserecords during
iocInit. If I set the field PINI to YES, i would expect accordng to the
documentation, that the record gets processed once during iocInit. But it dos
not as a call to dbpr with the record name gives SEVR: Invalid.
Only after triggering the record with dbtr the revcord gets processed.
I'm using EPICS base 3.14.12.4 on an arm Platform. But I have seen the same
behaviour on an x86_64 machine.
Is my understanding of the documentation wrong, or do I need additional fields
to be set to get the record processed during init?
