Why Automotive Manufacturers Are Augmenting Data Historians, Not Replacing Them

A modern vehicle assembly line generates more time-stamped telemetry before lunch than most data historians were built to hold: weld temperatures, torque readings, and vibration traces from every robot, torque tool, vision system, and test stand, and on most historians, each signal carries its own line-item cost because the systems are still priced per tag. That model was fine when data was scarce; it breaks down as OEMs and Tier 1 and Tier 2 suppliers add sensors, stations, and higher sampling rates every year, turning instrumentation into a budgeting exercise before it becomes a visibility g
