Experimental Physics and
Industrial Control System

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 ?

 

Thanks

Alfio
