selected with a 24 V signal, see
24 V Input " on page 64.
NOTICE
Only VDP devices with the same resolution may be connected to a Y-repeater.
NOTICE
While booting the control cabinet PC, switching from one to another operator
display is not permitted since the display resolution will be wrong or not be
identified.
NOTICE
The operator displays are to be supplied with voltage either before or at least
at the same time as the control cabinet PC.
Y-repeaters can be used in a cascaded way: Maximum two further Y-repeaters
can be connected to a Y-repeater. Thus, four operator displays can be con‐
nected to one control cabinet PC. As the screen signals are transmitted to all
the operator displays, data can only be entered using the active operator dis‐
play. Which of the four operator displays can be used as active operator display
to operate the control cabinet PC is to be selected with a 24 V signal. For the
switching, please refer to
