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.
