• When the circuit diagram is transferred from EZSoft (PC) or
from the memory card to EZD, the retentive actual values
are reset to 0. This also applies when there is no program
on the memory card. In this case the old circuit diagram is
retained in EZD.
• When changing the respective retentive range.
• When the circuit diagram is deleted via the DELETE
PROGRAM menu.
Transferring retentive behavior
The setting for retentive behavior is a circuit diagram setting.
In other words, the setting of the retentive menu may also
under certain circumstances be transferred to the memory
card or by uploading or downloading from the PC.
Changing the operating mode or the circuit diagram
When the operating mode is changed or the EZD 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 theEZD circuit diagram
If a modification is made to the EZD circuit diagram, the actual
values will be retained.
Changing the startup behavior in the SYSTEM menu
The retentive actual values are retained in EZD regardless of
the setting.
Modification of the retentive range
If the set retentive ranges are reduced, only the actual values
saved in the range will remain.
If the retentive range is extended, the older data is retained.
The new data is written with the current actual values in RUN
mode.
