PI Interface for Bailey Infi90 77Appendix Ebb Terminology To understand
this interface manual, you should be familiar with the terminology used in this document.
Buffering Buffering refers to an interface node’s ability to store temporarily the data that interfaces collect and to forward these data to the appropriate PI Servers.
N-Way Buffering If you have PI Servers that
are part of a PI Collective, PIBufss supports n-way buffering.
N-way buffering refers to the ability of a buffering application to send the same data to each of the PI Servers in a PI Collective. (Bufserv also supports n-way buffering to multiple PI Servers however it does not guarantee identical archive records since point compressions attributes could be different between PI Servers. With this in mind, OSIsoft recommends that you run PIBufss instead)
ICU ICU refers to the PI Interface Configuration Utility. The ICU is the primary application that you use to configure PI interface programs. You must install the ICU on the same computer on which an interface runs. A single copy of the ICU manages all of the interfaces on a particular computer. You can configure an interface by editing a startup command file. However, OSIsoft discourages this approach. Instead, OSIsoft strongly recommends that you use the ICU for interface management tasks.
ICU Control An ICU Control is a plugin to the ICU. Whereas the ICU handles functionality
common to all interfaces, an ICU Control implements interface-specific behavior. Most PI interfaces have an associated ICU Control.
