Switching times of the Y-repeater
12.2.1
Switching times without devices at the USB ports
To ensure a proper operation of the operator display, ensure ap‐
plicatively that the operator display toggles after the completion of
the previous operator display toggling. To complete an operator
display toggling, toggling can for example be impeded using an
additional discrete timing element (monoflop) or via a respective
logic in the PLC program. Basically, it has to be impeded applica‐
tively that an operator display toggling is toggled during an opera‐
tor display toggling. Due to the toggling times with devices to the
USB ports, we recommend a temporal toggling lock of 30 sec‐
onds. Depending on the real operating conditions, it is possible to
shorten this temporal toggling lock.
If an active operator display is disabled, it takes some seconds until the ena‐
bled screen can be operated. The time interval is the so-called "switching
time". This switching time depends on whether USB devices are connected
to "XUSBx" connections and on the used USB mode.
To achieve faster values in the standard USB mode, all connected operator
displays have to be operated in the standard USB mode. The standard USB
mode can be used up to a cable length of 30 meters. The DIP switch on the
rear panel of the operator display has to be set correspondingly.
