By combining TDengine\u2019s scalable time-series engine with semantic integration, we\u2019ve created a unified view of machine operations and domain knowledge that is both high-performance and explainable. This semantic approach lets us ask cross-domain questions and combine expert logic with real-time data \u2014 without building fragile custom pipelines.<\/p>\n<\/blockquote>\n\n\n\n

Frequently Asked Questions<\/h2>\n\n\n
\n
\n
\n

What is PI System and why look for an alternative?<\/h3>\n
\n\n

PI System is a long-established data historian widely used in industrial operations. However, it can be expensive, closed, and challenging to scale in modern, cloud-native environments. Many organizations are exploring alternatives that offer better performance, lower cost, and easier integration.<\/p>\n\n<\/div>\n<\/div>\n

\n

How does TDengine compare to PI System?<\/h3>\n
\n\n

TDengine is a modern time-series database designed for IoT and industrial data. Unlike PI System\u2019s traditional architecture, TDengine is cloud-native and AI-native, horizontally scalable, and built on an open-source core.<\/p>\n\n<\/div>\n<\/div>\n

\n

Can TDengine replace PI System entirely?<\/h3>\n
\n\n

In new deployments, yes. TDengine can ingest, store, and analyze the same industrial time-series data that PI System handles. TDengine also provides a zero-code data connector so that you don’t need to rip and replace existing PI System deployments.<\/p>\n\n<\/div>\n<\/div>\n

\n

Can TDengine IDMP replace PI AF and PI Vision?<\/h3>\n
\n\n

Yes. TDengine IDMP offers equivalent modeling (Elements, Templates, Attributes) and built-in dashboards with AI-powered analytics.<\/p>\n\n<\/div>\n<\/div>\n

\n

How does TDengine integrate with existing industrial tools and standards?<\/h3>\n
\n\n

TDengine supports industry-standard protocols and interfaces such as MQTT, OPC, JDBC, and ODBC. This makes it easy to integrate with data collection systems as well as visualization, analytics, and BI platforms\u2014similar to how PI System connects, but with more openness and less vendor lock-in.<\/p>\n\n<\/div>\n<\/div>\n

\n

What are the cost advantages of TDengine vs. PI System?<\/h3>\n
\n\n

TDengine\u2019s core-based pricing model is more flexible that PI System’s tag-based licensing, and you only pay for the resources you use. Many customers report dramatic reductions in infrastructure and licensing costs compared to PI System.<\/p>\n\n<\/div>\n<\/div>\n

\n

What makes TDengine more scalable than PI System?<\/h3>\n
\n\n

TDengine uses a distributed, cloud-native architecture that scales horizontally\u2014just add more nodes to handle more devices or higher data frequency. PI System\u2019s architecture is more centralized, which can make scaling complex and costly.<\/p>\n\n<\/div>\n<\/div>\n

\n

How does TDengine support AI and machine learning compared to PI System?<\/h3>\n
\n\n

TDengine is an AI-driven platform that includes AI functionality out of the box, most notably zero-query intelligence, which uses AI to generate visualizations and real-time analysis tasks without requiring prompts or queries. TDengine TDgpt also enables AI\/ML-based forecasting and anomaly detection. By contrast, PI System does not provide native AI capabilities\u2014users typically need to purchase and integrate external analytics modules or rely on third-party platforms.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n
