Getting Familiarized with the SIMATIC Field PG P42-16 SIMATIC Field PG P4 ManualA5E00180080-04CautionThe Field PG P4 supports different operating modes, according to the settings inthe Windows power options. The power options are preset at the factory in such away that the device always switches to defined operating modes (On, Standby,Hibernate, Off).When changing these settings or updating the device with additional hardware (forexample, USB components) or additional software, the operating modes can beinfluenced in such a way that the device can no longer switch to the hibernate orstandby mode. Although the screen is dark, relevant components remain activeand consume power.Before transporting the Field PG P4 in the carrying case, always shut it down orset it to hibernate mode. You can recognize these modes when all status LEDs areswitched off after the power supply has been disconnected. By doing this you canbe sure that the device is not switched on during transport and that the battery isnot unintentionally discharged.Energy OptionsYou can optimize the energy consumption of your PG using the energy optionswhile maintaining the PG in operate state.In Standby mode the screen and the hard disk drive are switched off to relieve thebattery pack. After you switch the PG back to normal mode the desktop is restoredwith your last configuration. Since PG memory information is not written to the harddisk drive, you should save your job before you switch the PG to standby mode.Information stored in memory is lost in case of a power failure.NoteSelect this mode if you briefly interrupt your work (few hours).In Hybernate mode the screen and hard disk drive are switched off. All data inmemory is stored to the hard disk drive before the PG is switched off. When youswitch on your PG again, all programs and documents that were opened at thetime of shut-down are restored to the desktop. Hybernate mode relieves thebattery pack even more than Standby mode. However, it requires a longer time toreactivate the PG from this hybernating state.NoteSelect this setting if you want to interrupt your work over an extended period(several hours) or over night.Briefly push the On/Off button to reactivate the PG from Standby or hybernatemode. In standby mode the system LED flashes, in hybernate mode all displaysare switched off.
