All flat screen displays feature touch screen functions.
They consist of the following components:
D Thin film transistor (TFT) display
D touch screen
D Backlight.
The display elements are located behind a splash-proof sealed film.
In addition, the following elements are located on the front panel
D Membrane keys (only CPS21T version M)
D Control devices for START, STOP and EMERGENCY-STOP (only
CPS21T with keypad)
D Key controller.
Due to its shallow installation depth, the TFT (Thin Film Transistor) display is
ideally suited to the subject control panel application. It features excellent
contrast and wide angle viewability. The display colours are adapted to the
requirements of the application environment by means of settings in the ope-
rating system, or via the respective application software.
The display of the control panel CPS21T is produced via 2 lines with the
Bosch IPC300 via the Gigabit interface LCD and via the power supply con-
nection X33 (refer to section 6).
The display resolution must be selected in the connected IPC300 via the S1
DIP switch (see diagram below):
