Carrier Arm Touch Terminal ETT 7321
The ETT 7321 is used to visualize automated process. Process diagnosis, operating and
monitoring automated functions are simplified using this terminal.
A projective capacitive touch screen serves as the input medium for process data and pa-
rameters. The output is shown on a 7” WVGA TFT color display.
With the LASAL visualization tool, graphics can be created on the PC, then stored and dis-
played on the terminal.
The available interfaces can be used to exchange process data or configure the terminal. In
the internal Flash memory, the operating system, application and application data are stored.

(3) The viewing angle is measured perpendicular to the display surface.
Due to the manufacturing process, individual pixel errors cannot be excluded to 100 % and therefore do not constitute
a reduction in quality.
4.4 Control Unit
Touch panel
projective capacitive touch panel
Cleaning
see chapter 14.1.
A projective capacitive touch screen is built into the panel, with which 10-
finger input, Zoom and gesture functions can be implemented.
Data can be input using fingers, a project capacitive touch pen as well as
with thin gloves. The device must always be grounded to ensure stable func-
tion of the touch screen. The touch function may still have to be individually
adapted to the respective environmental conditions.

4.5 Minimum Distance between Operating Elements for Multi-touch Appli-
cations
To guarantee smooth operation with multitouch applications, buttons and control elements
that should be operated at the same time must have the minimum clearance shown below
(depending on the estimated touch point).
The size of the buttons and operating elements directly affect the operability
of the application. Small operating elements should therefore be avoided.

5.1.1 X1: M12 Y-coded (supply, Ethernet)
n.c. = do not use
Problems can arise if a control is connected to an IP network, which contains
modules that do not contain a SIGMATEK operating system. With such de-
vices, Ethernet packets could be sent to the control with such a high fre-
quency (i.e. broadcasts), that the high interrupt load could cause a real-time
runtime error or runtime error. By configuring the packet filter (Firewall or
Router) accordingly however, it is possible to connect a network with
SIGMATEK hardware to a third-party network without triggering the error
mentioned above.

5.1.2 X2: USB 2.0 (Type A)
It should be noted that many of the USB devices on the market do notcomply
with USB specifications; this can lead to device malfunctions. It is also pos-
sible that these devices will not be detected at the USB port or function cor-
rectly. Therefore, it is recommended that every USB stick be tested before
actual use.
