2.1 Brief description
The multifunction panel 840 with TFT-touchscreen allows easy and clearly-arranged measured
data visualization, operation, configuration, and parameterization of the system.
The TFT color screen has a screen size of 21.3 cm (8.4“), a resolution of 640 × 480 pixels, 256
colors, and LED backlight.
As the interface between man and machine, the panel allows an optimum and clearly-arranged
view of the process status and the system parameters. In addition, it is perfectly suitable for the
display and operation of controller screens, process screens, the program editor, and the op-
tional recording function. Setpoint values, batch text, parameters, and configuration data can
be directly entered and changed by the user on the screen.
The process data that is transmitted by the system bus is shown in real time. Data archiving
and evaluation is made possible by established PC-programs.
In addition to the standard interfaces (LAN, USB), two optional serial interfaces can be con-
nected to a barcode scanner, modem, or other Modbus devices (master, slave).
The user can comfortably configure the multifunctional panel 840 with the setup program.
