For Windows nodes, the 10-minute rate averages (in events/minute) can be monitored with a client application such as ProcessBook.
Configuring I/O Rate Tags with PI ICU (Windows)
The PI Interface Configuration Utility (PI ICU) provides a user interface for creating and managing I/O Rate Tags.
PI ICU currently allows for one I/O Rate tag to be configured for each copy of the interface that is in use. Some interfaces allow for multiple I/O Rate tags.
The Enable IORates for this interface check box enables or disables I/O Rates for the current interface. To disable I/O Rates for the selected interface, uncheck this box. To enable I/O Rates for the selected interface, check this box.
Tag Status
The Tag Status column indicates whether the I/O Rate tag exists in PI. The possible states are:
Unknown – This status indicates that the PI ICU is not able to access the PI Server
In File
The In File column indicates whether the I/O Rate tag listed in the tag name and the event counter is in the IORates.dat file. The possible states are:
Yes – This status indicates that the tag name and event counter are in the IORates.dat file
No – This status indicates that the tag name and event counter are not in the IORates.dat file
Event Counter
The Event Counter correlates a tag specified in the iorates.dat file with this copy of the interface. The command-line equivalent is /ec=x, where x is the same number that is assigned to a tag name in the iorates.dat file.
Tagname
The tag name listed under the Tagname column is the name of the I/O Rate tag.
Snapshot
The Snapshot column holds the snapshot value of the I/O Rate tag, if the I/O Rate tag exists in PI. The Snapshot column is updated when the IORates/Status Tagstab is clicked, and when the Interface is first loaded.
