operating modes
A easy800 device recognizes operating modes RUN, STOP and BUSY.
RUN
In RUN operating mode the stored circuit diagram is run continuously until
STOP is selected or the power supply is switched off. The outputs are
activated according to the switch logic of the circuit diagram.
The circuit diagram and the parameters are retained in the event of a power
failure. All you will have to do is reset the real-time clock after the back-up
time has elapsed. In RUN operating mode:
•
the process image of the inputs are read.
•
circuit diagram is processed.
•
the process image of the outputs is transferred to the physical outputs.
The easy800 standard device with an integrated display does not start with
RUN mode if you deactivate the RUN MODE startup behavior.
easy800 devices without display and function keys have a different startup
behavior. The RUN START and CARD START functions are activated
automatically in this case, since no device operations for manual starting are
possible. More information on the CARD START function is provided on
section “Behaviour during upload/
download to card or PC”, page 305.
The switch from RUN to STOP and vice versa is carried out in the main
menu.
STOP
In STOP operating mode, the circuit diagram is not executed. Only in this
mode is circuit diagram entry, modification of the system parameters or
configuration of the easyNet possible. It is also possible to store the circuit
diagram on the external memory card or load them from the external
memory card.

DANGER
Configure your machine/plant so that the automatic starting of
the easy800 device never causes unintentional starting of the
machine/plant concerned.
Create your circuit diagram so that a defined and safe startup
procedure is always provided after the power supply is switched
on.
