Re: IOC with Normative Types

[Dave Bracey via Tech-talk <tech-talk at aps.anl.gov>]

If I generated an IOC with makeBaseApp.pl, how would I add a PV which is an NTScalar?  What record type would map to that?  How would I add device support to service the record?

 

I’m not finding any substantive documentation.  I feel I must not be understanding how this works.  Do the existing record types map to NT PV’s?

 

I’m expecting to see a new set of record types for the NT types, and to specify those in an IOC’s DB.  Is this not the case?

In short, you do almost nothing.

Instead of “softIoc” you use “softIocPVA” to run your database.

Instead of “caget” you can then use “pvget”, and instead of the Channel Access DBR.. types you get NT.

See PV Access intro on https://controlssoftware.sns.ornl.gov/training/2022_USPAS/,

or watch the video from 2022 EPICS meeting,

https://indico.cern.ch/event/1173788/page/25739-workshops-and-trainings,

https://indico.cern.ch/event/1173788/page/27020-video-material

 

If you build your own IOC, check the output of “makeBaseApp.pl -t example” for the crucial Makefile section to add PVA, as shown around 28 minutes into the video.

 

Thanks,

How does one build an IOC that integrates the NT types?

 

Are there any guides or examples -  i.e. a “Hello World” project anywhere?

 

I’m having a hard time finding any such material.
