Advanced Process Control, Controller Performance Monitoring and Alarm Management

Controller Performance Monitoring

The tuning parameters of a controller are optimal only at the time of tuning. Changes of process or operating conditions lead to a slow degradation of control quality. We continuously analyze the performance of all your controllers and visualize the results in a way that the condition of your plant becomes transparent at a glance.

Your gain ...

The utilization of controller performance monitoring provides:

• information about the effectiveness of every single control loop within your plant
• insight about promising starting-points for process control optimization
• timely identification of faulty field devices or equipment (e. g. wear of sensors or actuators, fouling)
• avoidance of unscheduled shutdowns by condition-based maintenance

Our approach

• continuous recording of all necessary process data tags
• calculation, evaluation and interpretation of statistical loop performance indices
• correlation analysis to identify the root cause for problems with interacting control loops
• hierarchical presentation of results from plant overview down to detailed analysis of single control loops
• integration of hardware and software within your control system infrastructure
