Retention 7-3
Transfer Retentive
Behavior
The setting for retentive behavior is a circuit diagram setting; in other words, the
setting of the retention menu may also under certain circumstances be transferred
to the memory card or during uploading or down loading from the PC.
Circuit Diagram Transfer (Behavior)
1760-L12BWB-xx and 1760-L18AWA ➞ Memory Module
When transfer is in this direction, the actual values are retained in Pico. The
retention setting is transferred to the card.
1760-L12BWB-xx, 1760-L18AWA ➞ PicoSoft
The Pico circuit diagram is stored. The actual values are retained in Pico. All Pico
circuit diagram settings are transferred to the “EAS” file.
PicoSoft ➞ 1760-L12BWB-xx, 1760-L18AWA
The transfer to PicoSoft is carried out according to the relevant settings.
Changing the Operating Mode or the Circuit Diagram
When the operating mode is changed or the Pico circuit diagram is modified, the
retentive data is normally saved together with their actual values. The actual values
of relays no longer being used are also retained.
Changing the Operating Mode
If you change from Run to Stop and then back to Run, the actual values of the
retentive data will be retained.
Modifying the Pico Circuit Diagram
If a modification is made to the Pico circuit diagram, the actual values are retained.
Changing the Start-Up Behavior in the SYSTEM Menu
The retentive actual values in Pico are retained irrespective of the MODE RUN or
MODE STOP settings.
NOTE
Even when the retentive relays M13, M14, M15, M16 (D1 to
D8) and the function relays C8, T8 (C5, C6, C7, T7) are deleted
from the circuit diagram, the retentive actual values are retained
after the changeover from Stop to Run as well as after the power
is switched off and on. Should these relays be used again in the
circuit diagram, they still have their former actual values.
