Siemens SIMATIC Field PG M4 Getting Started page 9

Possible operating states
You may press the ON/OFF button (power button), or close the display panel (lid switch), or
use the Windows Start menu to switch the PG from normal mode to one of the following
operating states:
● Standby mode (Save to RAM),
● Hibernate (save to disk), default setting
● Off (Windows is brought down).
When the device is brought down from Windows, the device automatically switches off. If the
device is not in Windows, it can be switched off using the on/off button.
Note
You can use Settings > Control Panel > Power Options in Windows XP to assign a response
to the on/off button and the lid. You can also assign these settings to the hot keys FN + F5
and Fn + F6.
Note
In accordance with the settings in the Windows Power Options, the Field PG supports
different operating states. The Power Options have been preset by the factory in such a way
that in the factory state the device always adopts defined operating states (On, Standby,
Hibernation, Off).
By changing these settings, and by adding extra hardware (such as USB components) or
software to the device, you can modify the operating states so that the device cannot switch
to Hibernation or Standby mode. Even though the screen display is dark, relevant
consumers remain switched on in the device.
Please remember to always bring down the Field PG or set it to Hibernation prior to
transporting in the backpack. When the device is in these states, all the status LEDs on the
device go off when you disconnect the power supply. This way you can ensure the device is
not switched on and the battery is not unintentionally discharged during transportation.
Press the on/off button briefly to reactivate the PG from Standby mode or Hibernation. In
Standby mode the device LED flashes, and in Hibernation all the displays are switched off.
