Data Logging and Process Control Software

Data acquisition systems need to be versatile and easily expanded when requirements grow. The Windmill software suite meets these needs and has proved itself in hundreds of applications including:

  • Quality assurance
  • Research and development
  • Environmental monitoring
  • Test and measurement

We package Windmill with all our hardware. It comes with free technical support for life.

We're sorry but we no longer offer Windmill as a stand-alone product. It is only available with data acquisition hardware.

Truly Modular | Testimonials | Is Windmill Suitable for You?

Truly Modular

Each Windmill program concentrates on doing a single job and you simply run as many programs as you need. You can run several copies of each program, which means there are no fixed limits to the size of a Windmill system. Windmill programs include logging, charting, process mimics, alarm logging, PID control and sequence control.

You can also build specialised modules using a programming language like Visual Basic. Let Windmill take care of the hardware configuration and control, logging to disk, and so on. The finished system could use any of the hardware supported by Windmill.

Virtual Instrument, HMI and Process Mimic Generator: Windmill Graphics

Use Windmill Graphics to create a virtual instrument, process mimic, annunciator panel, wiring diagram or any hmi you choose.
An example of a process mimic created by Windmill Graphics

Create hmi windows with Windmill Graphics. This program customises the Windmill software suite, making a versatile system that is unique to your application. The window continuously reflects the state of the system in the real world. Once you've created a window you can protect it from further editing. You can make the display a simple front end, or show enough detail to keep the even the most data hungry happy. Virtual instruments, process mimics, annunciator panels, wiring diagrams... it's entirely up to you.

Programming Tools

The Windmill Test Sequence software adds many more facilities to the standard Windmill and Streamer software. For example, Test Sequence lets you:

  • Perform PID (proportional-integral-derivative) control
  • Monitor alarms and automatically take appropriate action
  • Check if a condition is true before doing something - eg if a temperature is greater than 20 oC then switch off the heater
  • Start and stop logging according to conditions or time of day
  • Ramp output values up and down
  • Send key-presses to other Windows programs like Excel
  • Loop several times through a command sequence - useful, for instance, if you wanted to slowly rotate a head one degree at a time

To use Test Sequence you simply create a text file containing a list of commands, and tell Test Sequence to run it.

The Help file supplied with Test Sequence gives loads of examples on how to perform tasks, and we are happy to help if your application isn't covered. As with the other Windmill programs, Test Sequence is packaged with all our hardware.

Testimonials from Windmill Users

"This seems like the best, most versatile, and professional data acquisition/processing suite I have seen. "
