Send rate (milliseconds)
Send rate is the time in milliseconds that PIBufss waits between sending up to the Maximum
transfer objects (described below) to the Historian Server. The default value is 100. The valid
range is 0 to 2,000,000.
Maximum transfer objects
Maximum transfer objects is the maximum number of events that PIBufss sends between
each Send rate pause. The default value is 500. The valid range is 1 to 2,000,000.
Event Queue File Size (Mbytes)
This is the size of the event queue files. PIBufss stores the buffered data to these files. The
default value is 32. The range is 8 to 131072 (8 to 128 Gbytes). Please see the section
entitled, “Queue File Sizing” in the pibufss.chm file for details on how to appropriately size
the event queue files.
Event Queue Path
This is the location of the event queue file. The default value is [PIHOME]\DAT .
For optimal performance and reliability, Rockwell Automation recommends that you place
the PIBufss event queue files on a different drive/controller from the system drive and the
drive with the Windows paging file. (By default, these two drives are the same.)
Bufserv
For Bufserv, the paragraphs below describe the settings that may require user intervention.
Please contact Rockwell Automation Technical Support for assistance in further optimizing
these and all remaining settings.
