Generates PID parameter values for your process loops.

Auto-Tune conducts a step tuning test on your PID loops in either manual or automatic mode. The software collects process data and analyzes it, and then identifies a model that represents the true process dynamics.

Auto-Tune uses advanced Internal Model Control (IMC) based algorithms to calculate robust tuning parameters for the PID loop under test.

Process models generated by INTUNE software can also be used to tune model-based controllers.

Performs the tuning of both inner and outer cascaded loops in one test, eliminating the two-step manual tuning of cascaded control loops.

Evaluates the optimized PID parameters of both inner and outer loops in one step, and can perform single-step tuning in three modes:

• Open Loop Test
• Closed Loop Test
• Monitoring Loop Performance

Note: This functionality is not available in the INTUNE Single Loop version.

Handles and characterizes multiple disturbances that can affect the control loop and its PV. Users can define multiple feedforward controllers on each loop.

• Results of FF calculations are shown in a new tab within the results tab display; it is labeled “Disturbance Model.”
• Results of normal tune calculations are shown on another tab within the results tab display labeled “Process Model.”
• Users can switch between these two tabs to see the calculation results and the trend displays of the respective data sets.

Feedforward tuning can also be performed on archived process data using Data-Tune.

Once Auto-Tune has performed calculations, users have the option to download both the disturbance model and the feedforward parameters to the FF Controller.

Uses sophisticated pattern recognition techniques to analyze and interpret process data in real time and:

• Detect abnormal process characteristics, such as controller output (CO) saturation or sluggish response to process load changes or persistent oscillations.
• Confirm all abnormal process characteristics, and logs activity with a time and date stamp.

Designed for continuous background operation, when activated, Adapt-Tune can perform self-tuning in either Advisory or Automatic mode:

• Advisory mode: Recommends PID changes and prompts operator to acknowledge and download.
• Automatic mode: Recommends PID changes and automatically downloads to the controller; creates message in event logger

Use off-line with imported ASCII data to generate process models and suggest PID tuning parameter values.

INTUNE typically requires a data file with columns of data containing PV, SP, and CO data.

Use off-line for predicting the performance of your PID control using different PID factor settings.

• Automatically upload process models generated by INTUNE and perform “what-if?” type analysis, avoiding expensive trials on your real process.
• Use the Compare PIDs feature to simulate and compare the effects of up to four different sets of PID terms on your process—without intruding on or changing your process.
• Access online, real-time simulation capabilities for PID and non-PID process elements.

Provides reporting to document performance, tuning, and simulation, as well as your system configuration, device setup, and communications health.

• 14 different report types offer flexibility and convenience.
• Generate reports on demand, periodically, or based on an event trigger.
• Several reports offer ActiveX controls for interactive viewing of trends and key data.
