Hi Andrew,

 I could spend a small portion of my life to help this. However, you

and community should be OK with my bad English first :) If it is OK,

please guide me how to do this.

Hi Eric,

 While I am reading your email, I remembered my old question again,

and I actually am writing similar DB file recently.

 I would like to sync a PV value of Set with a PV value of RB in the

case when an IOC should be restarted with the assumption that the device

is ON. I asked Michael (MD), his codes help to figure out how to do this

long ago.

 It only covers 50% of your case. I hope it may help you more to make

your ioc robustly. Here is db snip codes

``` ----- snip -----

record(bo, "$(P)Update-Cmd")
{
	....
	field(PINI, "YES")
	field(ZNAM, "Revert")
	field(ONAM, "revert")
	field(FLNK, "$(P)Update:Fout_")
}

record(fanout, "$(P)Update:Fout_")
{
	.....
	field(LNK1, "$(P)PLL-RB")
	.....
}

record(bo, "$(P)PLL-Sel")
{
	....
	field( OUT, "@a.proto setVal(LO,i) $(PORT)")
	field(ZNAM, "Open")
	field(ONAM, "Closed")
	field(FLNK, "$(P)PLL-RB")
}

record(bi, "$(P)PLL-RB")
{
	....
	field( INP, "@a.proto getVal(LO,i) $(PORT)")
	field(ZNAM, "Open")
	field(ONAM, "Closed")
	field(FLNK, "$(P)PLL-RB_")
}

record(longout, "$(P)PLL-RB_")
{
	field( DOL, "$(P)PLL-RB NPP")
	field(OMSL, "closed_loop")
	field( OUT, "$(P)PLL-Sel NPP")
}

``` --- snip snip -----

   Thank you.

   Best,

   Han

Is there a 3.15 version of the record reference manual somewhere?  The
one I’ve been using
https://wiki-ext.aps.anl.gov/epics/index.php/RRM_3-14
is clearly old.

No, using a wiki didn't work well with multiple parallel releases, and
updating all those tables is almost impossible, so we started converting
those pages into Perl POD format inside the record.dbd file.

We strip off the POD before installing the DBD files, and generate HTML
from the POD and DBD info as part of the Build process (so the tables
get updated automatically). Unfortunately as you'll see if you look in
your base-3.15/html directory though we haven't got terribly far with
the conversion process. Help with this is always welcome, email me!

My quick attempt at trying the above with the 4 changed to a 5 didn’t
result in much useful….

Check the release notes for a description of the record-type changes:
