No longer do you have to contend with LEDs, switches, pushbuttons, and keypads. Touch.PLS graphically depicts your application, while providing machine settings and status and production data. All  programming and fine-tuning of the PLS settings occurs in a Windows-type environment. While the unit   comes with predesigned screens, AVG Automation's uWIN software makes it easy to create or customize   screens to suit your particular application.
