Hi Sorry if I am resuming an old thread, But I did not find any updated documentation about this topic. According to the EPICS wiki (which I think is not updated) https://wiki-ext.aps.anl.gov/epics/index.php/RRM_3-14_dbCommon The max allowed characters for PV name are 60 + NULL Which is common all the records type. However if I look at the ai record wiki in the Display Parameter section https://wiki-ext.aps.anl.gov/epics/index.php/RRM_3-14_Analog_Input#Operator_Display_Parameters I see that there is a limitation on the displayed .NAME field which is 29 char + NULL even if it I guess from 3.15 on is 39 + NULL. Could you please clarify why you have this limitation when the .NAME field is called ?
