Refer to the operation manuals for specific Units for other setup data.
Backup Files (Not
Supported by CS-series
CS1 CPU Units That Are
Pre-EV1) The files in the following table are created automatically when data is trans-
ferred to and from the Memory Card during backup operation.
Note 1. Make sure the names of the files used for backup are BACKUP @@ .
2. The CIO Area, WR Area, Timer/Counter Completion Flags and PVs, and
force-set/force-reset data that is read from the Memory Card at startup will
be cleared. This data can be retained with the following PLC Setup set-
tings: IOM Hold Bit Status at Startup and Forced Status Hold Bit Status at
Startup.

• This file must exist on the Memory Card when
reading data from the Memory Card during
backup.

backup.
BACKUPDM .IOM General-purpose DM
Area • Contains DM data from D00000 to D19999.
• This file must exist on the Memory Card when
reading data from the Memory Card during
backup.
BACKUPE @ .IOM General-purpose EM
Area 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.
