LOAD mode and SAVE mode

Use the LOAD mode and SAVE mode to retain contact comments, data memories,
and counter current values beyond the backup period or to securely hold important
data.

LOAD mode:
In this mode, contact comments, data memories, and counter current values stored
in the EEPROM are loaded into RAM. Contact comments and analog trimmer values
written in the EEPROM and devices specified by the holding function against power
interruption of the MEMSW instruction are read.

➮ For more about the MEMSW instruction, refer to "MEMSW" (p.3-92).

SAVE mode:
In this mode, all of the set comments, data memories, counter current values, high-
speed counter current values, high-speed counter comparator set values, and
analog trimmer values are saved in the EEPROM built in the Visual KV Series basic
unit.

Never change the operation mode while a ladder program is being transferred.
If the operation mode is changed at this time, the ladder program may not
transfer correctly.

Display in LOAD/SAVE mode

When the key is pressed, loading/saving is completed and "End" is displayed in
the bottom line for 3 seconds.

Note 1: Both LOAD and SAVE modes are available only in PROGRAM mode. If
LOAD or SAVE mode is forcibly executed in RUN mode, the error code "Err210" is
displayed and the Visual KV Series is stopped.

Note 2: If LOAD mode is executed without executing SAVE mode at all, the error
code "Err212" is displayed. (In this case, the Visual KV Series is not stopped.)

Note 3: When LOAD mode is executed, the basic unit is automatically reset and
stopped (in PROGRAM mode).

Note 4: When the setting is changed in the system mode, it is reflected within 1
scan + 50 ms.
