12 FUNCTION LIST
CPU module data backup/
restoration function
Backs up data such as program files, parameter files, and
device/label data files in a CPU module to an SD memory
card. The data backed up can be restored as necessary.

function
Out-of-group I/O
fetch
Enables loading input (DX) and buffer memory of the
intelligent function module by accessing the non-
controlled module of the CPU module.

startup
Synchronizes the startup of CPU modules in a multiple
CPU system so that operations of all the CPU modules
start at the unified time.

Label
initialization
function
Label initialization
after converting
all programs
(reassignment)
All the label areas will be initialized (initial values are set if
the values have been set, or the labels are cleared to zero
if not) when the CPU module is powered off and on or the
o
per
ating status of the CPU module is switched from
STOP to RUN after data is rebuilt (reassigned) with the
engineering tool and then written to the programmable
controller.

(Reassignment)
Label initial value
reflection setting
With the default settings, initial label values are not set in
labels when the operating status of CPU module is
switched from STOP to RUN even though the label initial
values have been set for the labels. This function can set
whether or not to set label initial values when the
operating status of the CPU module is switched from
STOP to RUN.

Value Reflection Setting
Routing setting Sets the communication path required for transient
communication to the stations on the different network.
Page 367 ROUTING
SETTING
Label access setting from external
device
Enables communications specifying the global label name
from the GOT and external devices using SLMP.

Latch
function
Latch with a
battery
Holds the device/label data in the CPU module even at
power-off.
Page 511 Latch with
Battery
Initial device/label value setting Sets the initial values of devices and labels used in the
program directly (not via the program) to the devices,
labels, and buffer memory areas of intelligent function
modules.
