Example:
M9 to M12, counters C5 to C7, C8 as well as timing relays T7 and T8 are
retentive.Indicated by the tick on the line. Indicated by the tick on the line.
The default setting of easy is selected so that no retentive data is selected.
In this setting, easy works without retentive actual values if a valid circuit
diagram is present. When easy is in STOP mode or has been switched to a
de-energized state, all actual values are cleared.
5.9.3 Deleting retentive actual values
Requirement: The easy500/700 control relay is must be in
STOP
mode.
The retentive actual values are cleared, i.e. reset to 0 if:
•
a new program is transferred
without
an activated retentive range from
the easySoft or memory card to the control relay.
This also applies if there is no program on the memory card (in this case
the old program is retained in the control relay).
•
the selected retention of a marker, function relay or the text display is
switched off in the System menu SYSTEM, RETENTION... of the control
relay.
•
the program is deleted in the main menu of the control relay via
PROGRAM..., DELETE PROG.
•
the marker range M1 to M16 is cleared of its retentive actual values with
the master reset function relay activated in mode Z2 or Z3.
The operating hours counters are always retentive. The actual values can
only be reset by means of a special reset operation from the circuit diagram.
The retentive actual values are retained if:
•
a new program
with
an activated retentive range is loaded from easySoft
or the memory card to the control relay.
•
the program in the control relay is deleted via easySoft.
5.9.4 Transferring retentive behavior
The setting for retentive behavior is a circuit diagram setting; in other words,
the retention setting is on the memory and is transferred with the circuit
diagram when uploading or downloading from the PC.
5.9.5 Changing the operating mode or the circuit diagram
When the operating mode is changed or the easy circuit diagram is modified,
the retentive data is normally saved together with their actual values. The
actual values of no longer used relays are not retained.
