Description
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.
Enables loading input (DX) and buffer memory of the
intelligent function module by accessing the non-
controlled module of the CPU module.
Synchronizes the startup of CPU modules in a multiple
CPU system so that operations of all the CPU modules
start at the unified time.
Communicates data between CPU modules in a multiple
CPU system.
Executes an interrupt program at the fixed communication
timing set in parameter.
Prevents unauthorized access to programs (in units of
POUs).
Prevents unauthorized access to programs (in units of
program files) or unauthorized execution of programs.
Prevents unauthorized reading/writing of data from/to
files.
Identifies the IP address of external devices over
Ethernet, and blocks access from an invalid IP address.
Limits access from external devices to the CPU module to
the specific communication route via Ethernet.
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
operating 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.
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.
Sets the communication path required for transient
communication to the stations on the different network.
Enables communications specifying the global label name
from the GOT and external devices using SLMP.
Holds the device/label data in the CPU module even at
power-off.
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.
