Aspen Watch™

Sustainability and performance monitoring for advanced process control applications

Aspen Watch is part of Aspen’s sustainability solution for APC. It provides performance monitoring with standard and custom KPIs, generates advice to operators based on expert rules, and enables engineers to monitor PID control loops. It provides full uncompressed historization and visualization of all controller-related data on a cycle-to-cycle basis. Aspen Watch is a core element of AspenTech’s aspenONE™ Advanced Process Control applications.
