CUTOUCH Overview
The Cutouch is a Cubloc Core with an integrated LCD and Touchscreen. It can be programmed to draw
graphics (lines, circle, etc...) on the LCD and to read the coordinates of touch inputs from a user.
The Cutouch provides a new approach to employing a touchscreen and PLC in the automation field. The
cost of a separate touchscreen, LCD, and PLC can be significant, but the Cutouch provides and
integrated solution at a relatively low cost..
Futhermore, the Cutouc is programmed is BASIC, a language that is quite easy to learn and use.
