OSIsoft PI Server Client Access
Port 545 is primarily used for communication between OSIsoft PI Servers and client systems. The PI System is a widely deployed industrial data management platform that collects, analyzes, visualizes, and shares large amounts of high-fidelity, time-series data from various sources including sensors, controllers, and SCADA systems. This port supports connectivity and data exchange between the PI Server infrastructure and client applications..
Port 545 enables client access to OSIsoft PI Servers, a critical component in industrial environments for managing real-time operational data. The PI System supports the collection and aggregation of sensor outputs, control signals, and system events then organizes this data within a centralized repository. Client applications leverage port 545 to send queries, perform analytics, and retrieve time-series data necessary for monitoring and optimization.
Communication over port 545 generally utilizes proprietary protocols optimized for high-volume, low-latency data transfers crucial for real-time data monitoring and analytics. Interfaces can include custom APIs, SDKs, or standard remote data access libraries embedded within OSIsoft’s client toolset, often integrated with visualization dashboards and analytics engines.
Given its role in industrial data flows, port 545 is commonly configured within secure, isolated network architectures. Its use often overlaps with other protocols and ports dedicated to historian and SCADA system communication, but it remains an essential conduit tailored to OSIsoft’s data structures and workflows.
