INTUNE Tuning Tools

INTUNE Productivity Tools

Using INTUNE® tuning software, you get better PID loop control results, with tighter tolerances and reduced scrap and downtime. The ability to maintain all your PID loops at their optimal operating conditions translates immediately into huge savings in manufacturing costs and higher productivity.

Learn how you can use these INTUNE productivity tools for optimal tuning:

INTUNE Tuning Tools

Results page displays trend data used, process model parameters, model correlation statistics, and 3 sets of PID parameters.

Auto-Tune

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.


INTUNE Tuning Tools

Evaluates parameters of the inner and outer loops in one step. This figure shows the result for the outer cascade loop.

One-Shot Cascade Auto-Tune

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.

The Disturbance Model results tab shows the model, transfer function, and correlation statistics.

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

Feedforward Compensation Auto-Tune

The Feedforward Controller (FF) was created to handle and characterize multiple disturbances that can affect the control loop and its PV. Users can define multiple FF 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.

FF 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.

This display of the Adapt-Tune feature shows the Event Log and PID control box.

Adapt-Tune

The Adapt-Tune feature is designed for continuous background operation. When activated, it can perform selftuning in either Advisory or Automatic mode.

  • Advisory mode: Recommended PID changes prompt for operator acknowledgment and download
  • Automatic mode: Recommended PID changes are automatically downloaded to the controller, with a message to the event logger.

The Adapt-Tune feature uses sophisticated pattern recognition techniques to analyze and interpret process data in real time.

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

Data-Tune

INTUNE's tuning tools include an off-line data tuning tool that uses 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.


INTUNE Tuning Tools

The Compare PIDs Online Simulation plugin allows users to preview the action of up to 4 sets of PID parameters. This shows 2 sets.

Simulation

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

  • Automatically uploads process models generated by INTUNE and performs "what-if?" type analysis, avoiding expensive trials on your real process.
  • With the Compare PIDs feature, you can simulate and compare the effects of up to four different sets of PID terms on your process—without intruding on or changing your process.
  • Offers online, realtime simulation capabilities for PID and non-PID process elements.

INTUNE Tuning Tools

Auto-Tuning results report with ActiveX Trend.

Web-Based Reports

Web-based reports document your performance monitoring, 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.

Workspace

INTUNE's Workspace is the userfriendly way of navigating from initial project setup to advanced operations.

The Loops Toolbar creates and manages loops, controllers, and functionality.

An unlimited number of PID loops and controllers can be configured and grouped in projects for the 10-loop package.

The I/O Toolbar manages control devices such as PLCs and DCSs.

The Properties Toolbar shows a runtime view of properties for loops, devices, and controllers.

Connectivity

OPC Foundation MemberINTUNE connects to most I/O devices and their associated controllers using OPC technology. The OPC client allows easy access to any control system through the controller OPC server.

For the more commonly used controllers, INTUNE automatically maps the parameters of the selected controller to the INTUNE controller object.

INTUNE maintains real-time connections with your process PID loops, and updates all process parameters at every sampling interval specified.

INTUNE is also its own OPC Server, so other clients have access to INTUNE's unique performance calculations and measures.
