Change the Operating Mode or the Circuit Diagram
When the operating mode is changed or the circuit diagram is
modified, the retentive data is normally saved together with the actual
values. The actual values of relays no longer being used are also
retained.
Change the Operation Mode
If you change from Run to Stop and then back to Run, the actual
values of the retentive data are retained.
Modify the Circuit Diagram
If a modification is made to the circuit diagram, the actual values are
retained.
Change the Startup Behavior in the System Menu
The retentive actual values will be retained regardless of the Run
mode or Stop mode settings.
Display Device Information Device information is provided for service tasks and for determining
the capability of the device concerned.
This function is only available with devices featuring a display.
ATTENTION
Even if the markers and function relays that were
retentive are deleted from the circuit diagram, the
retentive actual values remain when changing from
Stop to Run, and when switching the device off and
on. Should these relays be used again in the circuit
diagram, they will still have their former actual
values.
