The modular Windmill software suite offers data logging, alarm indication and sends data directly to other applications like Excel. You can also add process mimic generators to create your own data displays involving live moving bars, analogue meters, colour coded alarms, control buttons, changing icons and time and date labels.

Data can be passed to other software such as spreadsheets, databases and energy management software.
