VISION, EXPERIENCE, ANSWERS FOR INDUSTRY ARC VIEW MARCH 11, 2021 Sensor Data Integrity for Process Plants is a Problem: Here's How Users Can Solve It By Larry O'Brien Keywords Sensor Data Integrity, Cybersecurity, PAS, Plant Asset Management, Intelligent Field Devices Overview Data integrity of intelligent sensors has been a persistent problem in the process industries for decades. The ubiquitous spread of intelligent field devices, control valves, and analytical equipment held the promise of better management and maintenance of these devices, but – instead – created a huge data management problem. Sensor data almost always show inconsistencies across different applications that rely on their data. There is no "single version of the truth" that provides the true state of the sensor in a consistent manner across applications. Plant asset management systems (PAM), dis- tributed control systems (DCS), safety instrumented systems (SIS), and engineering applications like Hexagon's PPM division's Intergraph Smart ® Intrumentation frequently show a different picture of what the intelligent device looks like. These inconsistencies affect change management, device maintenance, overall plant performance, and can increase cybersecurity risk. Poor sensor data management is also a huge contributor to unplanned downtime, which ARC estimates costs the process industries over $1 trillion a year. ARC Advisory Group recently met with PAS to discuss the company's new solution to solve the sensor data management problem. To the best of ARC's knowledge, the PAS Sensor Data Integrity solution is the first vendor- Having pervasive intelligent sensors and actuators in process plants has created a significant data management problem for end users. The influx of less expensive and easier-to-connect IoT and wireless sensors exacerbates this problem, increases cybersecurity risk, and expands the threat surface. End users haven't had much luck solving this problem, often resorting to costly manual data reconciliation through spreadsheets. PAS recently released its Sensor Data Integrity offering, which provides a vendor-independent solution for sensor data and integrity management.
