Re: Help understanding DTYP Soft Timestamp

Hi Marco,

The part of that record which copies timestamps is the TSEL link pointing to the .TIME field of the record whose timestamp you want to copy. There is documentation for the TSEL and related TSE fields here, hope this helps:

Subject: Help understanding DTYP Soft Timestamp

 

Hello all. Today I came across this interesting record:

record(stringin, "$(P)$(R)customTimeTimestampIn") {
    field(DTYP, "Soft Timestamp")
    field(SDIS, "$(CUSTOM_TIMESTAMP) CP MS")
    field(DISV, "-1")
    field(TSEL, "$(CUSTOM_TIMESTAMP).TIME CA")
    field(INP,  "@%s.%f")
}

It's a record meant to get the timestamp from another record via CA.
I had never seen the Soft Timestamp DTYP before. After digging a while I found some e-mails on tech-talk

https://epics.anl.gov/tech-talk/2020/msg01593.php

But couldn't find the documentation on how to use this. Is there any specific link I should look for?

Thanks in advance,

Marco
