However, if the Historian Server contains an interface-specific Trust entry that allows a
particular interface program to write data, you must have a Trust entry specific to buffering.
The following are the appropriate entries for the Application Name field of a Trust entry:
Buffering Application Application Name field for Trust
Buffer Subsystem PIBufss.exe
PI API Buffer Server APIBE (if the PI API is using 4 character process
names)
APIBUF (if the PI API is using 8 character process
names)
To use a process name greater than 4 characters in length for a trust application name, use the
LONGAPPNAME=1 in the PIClient.ini file.

To select PIBufss as the buffering application, choose Enable buffering with PI Buffer
Subsystem.
To select Bufserv as the buffering application, choose Enable buffering with API Buffer
