Non-DCS (PLC) Version
Designed for smaller PLC-based control systems.
PID Loop Tuning as easy as:
- Select the controller.
- Specify PID address.
- Select Autotune.
With AutoTune, answer the questions, and your loop is tuned. Tunes
and analyzes loops from data collected in either manual or automatic.
During AutoTune, you have total control of the tuning process.
Get data for analysis and tuning from a setpoint change.

ExperTune Connects to ANY Controller
Over 500 controller algorithms supported.
How To Connect To Your Controller
ExperTune Saves Time and Increases Profitability
- Optimizes your control loops.
- Reduces tuning time from hours to minutes per loop.
- Improves product quality.
- Reduces waste and rework.
- Saves energy.
It's All In The Faceplate
When working with the software, click on the faceplate and you are on-line, live. From the
faceplate, change setpoint, output, mode and download tunings.
Performance Increase
Tells you how much better the response will be with the new settings.
Control Performance
Choose from:
- Optimal: minimum absolute error to step load - recommended
- Fast: quarter amplitude damping (approximates Ziegler Nichols)
- Slow: 10% overshoot
- Setpoint (Lambda) PID tuning.
Test different tunings in simulation before you download to find
the best one for your process.
Safety Factor
Adjust the safety factor for the response and robustness you want.
There is always a trade-off between fast tuning and sensitivity to
changing process conditions (changing gain and dead time ). The
fastest tuning with the lowest safety factor is also the most
sensitive to a changing process. Conversely, the slowest tuning with
the highest safety factor is the least sensitive or more robust.
ExperTune quickly lets you compare simulated time and robustness
plots, off-line, before you download PID values. Compares current to
new values.
Advanced Data Editing
Graphically zoom on the data you want to use. Clean up the data by
averaging or drag the mouse to change the data on the screen.
Tune Several Loops At Once
View the interactions of a loop on others. Save time tuning and on
start-ups by tuning several at the same time.
- Simulation. See the process response off-line before
you download tuning. Try "what if"—change a PID parameter and
instantly see the new response compared to current tuning. Set point or
upset response.
- Modeling. Up to second order with dead time. From
one chunk of data.
- Robustness.
Available only with ExperTune, this quickly shows the tradeoff between
tuning and stability. Compares current to new. See the
Robustness Presentation.
- Frequency response.
- More Analysis Options
The analysis windows are completely automated, integrated and
cohesive. Select a different model, change PID selection or enter
your own PID values and ExperTune instantly updates all plots.
ExperTune automatically analyzes loop data and reports on your valve condition.
