Configure n-way buffering for interfaces with PI Buffer Subsystem

The procedure in this section describes how you can use PI Interface Configuration Utility (PI ICU) to configure PI Buffer Subsystem and n-way buffering for an interface that sends data to a Data Archive collective.

Note: If you have configured interface failover, you must configure n-way buffering at both the primary interface and the redundant interface. Use PI ICU to ensure that each interface is dependent on PI Buffer Subsystem.

1. Click Start > All Programs > PI System > PI Interface Configuration Utility.

2. In Interface, select the interface.

3. In the page tree, select General.

4. Start buffering (PI Buffer Subsystem version 4.3 or later).

5. Verify that buffering is working as expected by doing one of the following:

   • If you are using PI Buffer Subsystem 4.3 or later, view the Buffering Manager dashboard.

   • If you are using an earlier version, see Verify that buffered data is being sent to PI Data Archive.
