• Contains DM data from D20000 to D32767.
• This file must exist on the Memory Card when
reading data from the Memory Card during
backup.
• Contains all of the data in the CIO, WR, HR, and
AR data areas as well as timer/counter Comple-
tion Flags and PVs.
• This file must exist on the Memory Card when
reading data from the Memory Card during
backup.
• Contains DM data from D00000 to D19999.
• This file must exist on the Memory Card when
reading data from the Memory Card during
backup.
Contains all of the EM data for EM bank @ with
addresses ranging from E@_00000 to E@_32767.
(The maximum bank number depends upon the
model of CPU Unit being used.)
This file must exist on the Memory Card when read-
ing data from the Memory Card during backup.
• When data is backed up to the Memory Card, all
of the data in each EM bank is automatically writ-
ten to a separate file.
• Contains all cyclic and interrupt task programs as
well as task data for one CPU Unit.
• This file must exist on the Memory Card when
reading data from the Memory Card during
backup.
• Contains all initial settings for one CPU Unit.
• The user does not have to distinguish parameter
data in the file by type.

• This file must exist on the Memory Card when
reading data from the Memory Card during
backup.
• Control backup data from one Unit or Board.
