Fig. 4-2 Change between the operating states of the ES720.1 (simplified)
The digits in the status diagram correspond to the possible operating state
changes of the ES720.1, initiated by events (trigger or timer) of the functions
"Wake-Up" and "Sleep" (see chapter 4.9.2 on page 29).
If the measurement is complete, the measured variables are safely stored.
Dependent on the configuration, the ES720.1 remain switched on or changes to
the operating state "Fast Boot Standby" or "Low Power Standby".
4.9.2 Events and Timers
The changes of the ES720.1 between operating states are triggered by events.
These events can be activated and deactivated in the configuration software and
combined with timers for an additional delay of the event.
The operating state changes in Fig. 4-2 on page 29 are each linked with a selec-
tion of the events and timers listed here.
