Learn about AVEVA™ PI System Connector 3

AVEVA PI System Connector 3 (PSC3) is the latest generation of the PI System Connector, designed to support modern deployment architectures and evolving security requirements.

This section introduces what’s new in PSC3, explains the key high-level differences compared to PI System Connector 2 (PSC2), and helps you determine whether upgrading to PSC3 is appropriate for your environment.

What's New in AVEVA PI System Connector 3

AVEVA PI System Connector 3 offers the following new features and functionality:

• Support for brokered and direct delivery models, enabling connectors to deliver data directly or through chained brokers to traverse DMZs and segmented networks while reducing overall architectural complexity.

• Improved scalability and manageability, featuring less configuration and components to manage along with easier troubleshooting.

• More robust caching behavior, providing greater resilience and automatic recovery during downstream outages.

• Release components (connector, broker, and configuration tools are now delivered in a single, integrated installer.

• New, simpler UI to easily manage and troubleshoot connector and broker components

• Enhanced migration support, including a dedicated migration utility and guidance for upgrading from PSC2.

• Support for OpenID Connect (OIDC) providing enhanced security and an improved user experience.

• Monitoring and health visibility, providing clearer insight into connector status, data flow, and operational conditions

• Enhanced monitoring and health transparency, offering better understanding of connector status, data movement, and operational states

How is PI System Connector 2 different from AVEVA PI System Connector 3?

This section highlights the high-level architectural and capability differences between PI System Connector 2 (PSC2) and AVEVA PI System Connector 3 (PSC3), focusing on how PSC3 modernizes deployment, resiliency, and network support.

Deployment model

PSC2 typically required a full connector stack at each network boundary, while PSC3 uses a cleaner separation between connectors and brokers to reduce duplication and configuration overhead.

Network and security handling

PSC3 is designed to better accommodate segmented networks and DMZs by introducing brokers that securely forward data across boundaries, rather than relying on tightly coupled relay components.

Operational complexity

PSC3 simplifies troubleshooting and maintenance by reducing the number of interdependent components involved in moving data end‑to‑end.

Upgrade path

PSC3 includes explicit migration tooling and documentation, whereas PSC2 upgrades typically relied on manual reconfiguration

Who should upgrade to AVEVA PI System Connector 3?

• Customers seeking to collect data from various locations and consolidate it into a centralized system.

• Organizations in controlled industries that are looking to simplify how they share data across their environments.

• Users aiming to simplify AF model duplication to facilitate data analysis, dashboard creation and ensure consistency in how assets and processes are modeled.
