1.1 Short Description
The hand-held terminal VPP 21.2 is a computer-based machine operator ter‐
minal consisting of
●
an enclosed plastic housing (degree of protection, total device: IP 40, de‐
gree of protection, front panel: IP 64)
● a TFT display with and without touch screen,
● depending on the variant, different display and operating components and
● an integrated efficient industrial PC.
VPP 21-type operator terminals are provided for bracket mounting. Because of
its design they are predestinated as "operator panel control". For this, special
buttons (control ON, control OFF, E-STOP) are mounted in the housing. On the
left and right three navigation keys are integrated. To communicate with exter‐
nal components standardized field bus systems are used.
The restricted extensible computer unit with power supply unit and field bus
connection is located in the so-called VPP 21 box installed in the plastic housing
of the VPP 21.
