AVEVA PI Server 2024 - Release Notes

Overview

AVEVA™ PI Server 2024 R2 is a feature release focusing on performance, accessibility, and manageability. This release also includes a variety of bug fixes and security remediations to improve the stability and functionality of the Data Archive and PI Asset Framework (AF).

The PI Server 2024 R2 installation kit has updated components for Data Archive, AF Server, PI Notifications Service, PI Analysis Service, and AF Client. Some of the components including Buffer Subsystem, PI SDK, and PI Collective Manager will remain at the same version as delivered by the previous release.

New features

The features in this section were introduced in the PI Server 2024 R2 release:

AF Client:

• File-based Known Servers Table (KST) Implementation for AF SDK Applications: Applications that utilize the AF SDK (Software Development Kit), such as PI DataLink, will now employ a file-based KST. This new approach is designed to facilitate easier access and management by loading known Data Archives from a file-based table. Meanwhile, PI SDK applications will use a separate, dedicated KST.

  For more information, see Manage and migrate the Known Servers Table.

• The Language Packs feature has replaced the Language Packs Multilingual User Interface (MUI): You can now select the Language Packs feature during a PI AF Client installation to set the user interface (UI) for PI System Explorer and PI Builder to a language other than English. A separate MUI kit is no longer required. Note that PI Builder will use the Office display language on the Excel Options menu if the language is supported.

For more information, see the PI AF Client Release Notes.

PI AF Server:

• Support for cloud-hosted database solutions: Prior to AVEVA PI Server 2024, SQL Server was the only backend database for Asset Framework. Now, you can also choose Microsoft Azure SQL Database to store and manage your Asset Framework data.

Data Archive:

• Improvements to the PI Archive Subsystem: Enhancements to read cache enables faster data reads when data is already in the cache. The enhancements allow for tuning the system to increase the read cache size without compromising the read time.

• New and changed tuning parameters -- The following tuning parameters have been added or changed:

  • Archive_MaxFreezeDuration parameter: Used to specify the wait time for the flush threads of each archive set to pause. Ranges from 20,000 to 60,000 milliseconds (ms). Defaults to 20,000 ms.

  • Backup_MaxFreezeDuration: Used to specify the wait time for a freeze duration. Ranges from 60,000 to 120,000 milliseconds (ms). Defaults to 60,000 ms.

• Improvements to Update Manager: This service has been enhanced to accept and process simultaneous requests, leading to faster response and recovery times after an outage.This improvement minimizes system downtimes and promotes rapid recovery after outages or system modifications. It also enables faster update deployment, backfill performance, client sign ups, and monitoring capabilities for prompt issue detection and resolution.

• Out-of-order event improvements: This enhancement allows for more efficient handling of out-of-sequence PI point values. Specifically, it enables large write and read operations to occur simultaneously without sacrificing performance or data integrity.

PI Server:

• Certificate Management for Data Archive and AF Products: The 2024 release of AVEVA PI Server enhances certificate management for Data Archive and Asset Framework (AF) products, supporting automatic TLS certificate rotation using AVEVA’s Platform Common Services (PCS). Administrators can choose automatic certificate renewal via Platform Common Services (PCS) or manual renewal for greater control. TLS version 1.3 is supported in this release. TLS is also required when using OpenID Connect (OIDC) authentication.

  Refer to Certificate management for Data Archive and AF products in the installation guide for detailed instructions on configuring and managing certificates in your environment.
