Using the PID Tuner, you can apply the latest insights in control engineering to your industrial environment with the click of a button. PID controllers in any software and hardware environment (Siemens, Allen Bradley, Omron, Arduino, etc.) can be optimally tuned with the PID Tuner.

The PID Tuner tunes PID controllers based on a model. Usually, this will be a model obtained from actual data. The procedure to obtain such a model is refered to as identification. The data should not just be ordinary data, but data obtained during a so-called identification experiment. Below, we explain the steps in the DotX PID Tuner that one usually will have to go through:
Step 1. connect the PID Tuner on-line, or switch on some data logger to use the PID Tuner later in off-line mode
Step 2. while the loop is active, perform a setpoint bump test, or gather data while setpoint is changed by a master loop. Also, perform an open loop bump test for identification purposes
Step 3. Identify a model from the experimental data obtained in step 2
Step 4. Select the PID type
Step 5. Tune the PID
Step 6. Verify

    Supports on-line and off-line mode

    In on-line mode, all required data are obtained in real-time, through OPC communication. In off-line mode, you can import data from files (csv format).

    Extensive Model Identification Options

    The PID tuning requires a System Model, and this model is usually obtained from data (model identification). The PID Tuner does not only support identification of the FOTD model, but also SOTD model.

    Supports tuning of all PID types

    Supports all PID types, among which DeltaV, Siemens, Omron, Rockwell , Yokogawa. Different vendors use different PID types. Therefore, we included all options: the parallel form, direct form, proportional band format and setpoint weight parameters. Scaling parameters, often not published, are found by automatic fitting.

    Extensive tuning options

    The PID Tuner supports tuning not only the P, I and D constants but also the other options supported by vendors, such as setpoint weighting, setpoint filtering, deadbands, rate and position limitations,
