PIDSnap

About PIDSnap

PIDSnap analyzes photographs of PID loop trend screens and faceplates to diagnose control issues and guide tuning adjustments. It distinguishes between problems that can be solved by tuning and those requiring mechanical intervention, such as valve stiction or output saturation. The tool performs a pre-flight check of loop configuration to identify structural issues before any tuning begins. Users upload trend images via a phone or computer, and PIDSnap classifies the response into one of eight fundamental loop signatures. If tuning is viable, it provides step-by-step guidance with observation-based criteria for each adjustment, ensuring changes are validated before proceeding. The process avoids model-based assumptions and relies solely on user-confirmed values from the faceplate. All outputs are informational and require manual implementation by the user, who remains responsible for process safety and compliance with management-of-change procedures. PIDSnap operates without direct connection to control systems and does not generate or store plant-specific data beyond the uploaded images.
