Was ist der beste Weg um diese Werte zu archivieren?

1.) Should the 8 values be made available as ‘individual’ scalar PVs on the embedded system as well?

I think yes.  


2.) Run a ‘converter’ on another system that maps the custom struct to scalar PVs?

As long as there is sufficient information to do so, then yes.

see also: https ://epics.anl.gov/tech-talk/2025/msg00928.php


3.) Another idea ?

Serve up the same data in both structures?

This would complicate your server, but would handle a situation where your current structure does not have sufficient meta-data for NTScalar (like a timestamp).
