Touch Operating Panel HZS 7321
The HZS 7321 is an intelligent terminal for programming and visualization of automated pro-
cesses. Process diagnostics as well as operating and monitoring automated procedures 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 build-in touch terminal.
The available interfaces can be used to exchange process data or configure the build-in ter-
minal. In the internal Flash memory, the operating system, application and application data
are stored.

n.c. = do not use
Problems can arise if a control is connected to an IP network, which contains
modules that are not running with a SIGMATEK operating system. With such
devices, 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.

X8: microSD Card
It is recommended that only storage media provided by SIGMATEK(Com-
pactFlash cards, microSD cards etc.) be used.
Order number for 512-Mbyte EDGE2 microSD card: 12-630-055
The number of read and write actions have a significant influence on the
lifespan of the storage media.
The microSD card is, in this case, not used as an exchangeable storage me-
dium and therefore should not be removed from the holder.
