4 Application Description for Small Operator Termi-
nals
4.1 The Concept
A uniform functionality and operating structure constitute key aspects
of the operating and monitoring concept across the entire product fam-
ily.
The small operator terminal of construction type VCP relieves the con-
troller completely of operating and monitoring tasks.
This applies to the operating mode Standard Mode in particular. In this
mode, devices reach their full performance capacity. In this context, the
small-sized operating terminal reads all required data independently
from the controller, and processes this further internally. On request,
the device writes data or data sets (of recipes) to the controller. The
device independently controls the display and the status LEDs.
You can also run the small operator terminal as an ANSI terminal in the
operating mode Transparent Mode. In this context, the device writes
each key actuation to the controller as a press and release code. The
controller uses escape sequences to control the display and the status
LEDs of the device.
All small operator terminals of construction type VCP are programmed
in the same way using the programming software VI Composer.
