Hardware-System Overview
2.1
Function
The new range of PCD7.D230, D231 and D232 terminals are remote graphic displays
for the Saia
®
PCS1 and the whole Saia
®
PCD range.
They have been developed for building automation and industrial applications. In
combination with the HMI-Editor, an add-on tool of the PG5 programming package,
they provide a simple way of implementing menu-driven user interface.
This new range consists of three different graphic displays:
PCD7.D230 easy to use! like a mouse.
The single-knob control has “turn” and “press” functions which
can be used to select submenu structures and different process
parameters.
PCD7.D231 with large keys
10 function keys allow to control a lot of processes, the auto-re-
peat function with 2 speeds allows to increment and decrement a
value easily.
PCD7.D232 with numeric keyboard and LED indication
8 function keys, 1 numeric keyboard, 8 LEDs allow to control,
enter values and control a process.
All terminals, with backlighting, have a resolution of 128 × 64 pixel and can therefore
be used for high quality representation too:
●
in plain text (8 lines x 20 characters) such as temperature, pressure, unit num-
bers, date, time, etc., and messages about operating states and alarms
●
in graphic mode (with the HMI-Editor only) to display graphic symbols, bar-
graphs…
In the basic equipment, the terminal offers RS 232, RS 422 and RS 485 inter
faces, which allows a broad range of configurations.
