Introduction
What is a
Video
Terminal
A VIDEO TERMINAL (VT) is a device that allows the user to control or
simply monitor a productive process. It can send commands using con-
figured by the user; it can send data determining the process on hand and
can display information deriving from the productive process. The informa-
tion can be in the form of an Alarm, an Information (Info-) Message or in
binary data format.
The VTs can be divided into two groups: those with a keyboard and those
without but equipped with a Touch Screen.
All VTs can be supplemented with accessories to boost and broaden their
performance.
VTs are connected to the device by means of a serial connection.
For the VT to function a project must be created and loaded into it. See
Software Manual.
For detailed information on individual VTs see the relevant chapters below.
