Operating States
Possible operating states of the Drive Recorder ES720.1 are "Off", "Low Power
Standby", "Fast Boot Standby" and "On".
4.8.1
Operating State "Off"
The ES720.1 is not connected with the external power supply and completely
switched off. The embedded PC of the module is shut down and all interfaces
are deactivated. The "Wake-Up" function (see chapter 4.9 on page 29) is deac-
tivated.
4.8.2
Operating State "Standby"
The ES720.1 is connected with the external power supply and is in one of the
two "Standby" operating states of the ES720.1:
• Operating state "Low Power Standby" and
• Operating state "Fast Boot Standby".
The module waits for a "Wake-Up" event; its occurrence changes the module
from the operating state "Low Power Standby" or "Fast Boot Standby" to "On"
and automatically starts the measurement.
Operating State "Low Power Standby"
In the operating state "Low Power Standby", the embedded PC of the Drive
Recorder is in the hibernating state ("Hibernate", "Suspend-To-Disk"). The cur-
rent consumption of the ES720.1 is relatively low in this operating state.
In the operating state "Low Power Standby", the current state is stored in the
hibernation file and the available settings are also saved.
The "Wake-Up" function is activated and the ES720.1 changes to a different
operating state dependent on the configured event.
If the operating state "Low Power Standby" is selected in the ES720.1 configu-
ration program, the Drive Recorder can start the recording of the measured vari-
ables with a median delay.
Operating State "Fast Boot Standby"
In the operating state "Fast Boot Standby", the embedded PC of the Drive
Recorder is in the hibernating state ("Standby Mode", "Suspend-To-RAM"). The
current consumption of the ES720.1 is relatively high in this operating state.
The functions "Wake-Up" and "Sleep" are activated and the ES720.1 changes
to a different operating state dependent on the configured event.
If the operating state "Fast Boot Standby" is selected in the ES720.1 configura-
tion program, the Drive Recorder can start the recording of the measured vari-
ables with a minimum delay.
4.8.3
Operating State "On"
In the operating state "On", all modules and interfaces of the embedded PC of
the Drive Recorder are activated. The module is ready for recording measure-
ments.
