I will attmpt to make it clear
in 3.14 - you database allows you to have 60 character names
channel access allows you to search for much longer names
but......
you cannot change the fields within the database that may refer to names that are longer than 40 characters as the channel access type dbr_string is configured to be 40 characters. This means that you can define the database to link any of these 60 character named records together - but you cannot change them over channel access during operation.


The caution for channel access clients must also be heeded. It is unclear that all of the clients have been tested with the longer names.
