Thanks all for your replies.
Ralph: using DRVH/DRVL instead of HOPR/LOPR indeed solves my issue. Thanks!
Ulrik: please find attached a screenshot of the records I’m now using (I was previously using HOPR/LOPR as you suggested) and one of the Phoebus configuration file. Even though the issue is now solved by using
DRVH/DRVL, I would still appreciate if you could tell me if there’s something else that could be improved in the logic I’m using.
Thanks,
Alessandra

Subject: Re: Changing runtime limits with Channel Access
Also keep in mind that the ao record has two sets of range/limits fields.
HOPR/LOPR - "Operating Range" - hints for clients (like Phoebus) how to display things.
DRVH/DRVL - "Drive Limits" - these limits are clipping the output value that the record will write.
Depending on your specific use case and application, you might want to set both to the same value, or both to different values, or only one, or only the other one. (Or none, for completeness.)
