Redundant
function
Operation mode
change
Switches the operation mode of the redundant system
between the backup mode for normal operation and the
separate mode for system maintenance while it is
running.
 Page 371 Operation Mode
Change
System switching Switches the systems between the control system and the
standby system to continue operation of the redundant
system when a failure or an error occurs in the control
system. For debugging and maintenance purpose, users
can switch the systems at any desired timing.
 Page 374 System
Switching
Tracking transfer Transfers the control data from the control system to the
standby system and maintains the consistency of the data
in the two systems to continue operation of the redundant
system when a failure or an error occurs in the control
system.
 Page 388 Tracking
Transfer
Memory copy
from control
system to standby
system
Transfers data such as parameters and programs in the
CPU module of the control system to the CPU module of
the standby system to maintain the consistency of the
memory in the two CPU modules.
 Page 405 Memory Copy
from Control System to
Standby System
System
consistency check
Checks whether the system configurations and files in the
CPU modules are the same between the control system
and the standby system when the redundant system is in
backup mode.
 Page 413 System
Consistency Check
Program
execution in both
systems
Detects an error in the external device or network of the
systems (control system and standby system)
respectively by executing a program that diagnoses
external devices and networks in both systems.

Execution in Both Systems
Redundant
system operation
setting
Sets the redundant system operation in the redundant
system settings of the CPU parameter.

communication
test
Checks the redundant function module itself for errors
when its communications are unstable.

Settings for
redundant system
with redundant
extension base
unit
Sets the operation of the redundant system with
redundant extension base unit in the redundant system
settings of the CPU parameter.

Redundant Extension Base
Unit
Automatic
recovery of the
CPU module of
the standby
system
Allows the CPU module of the standby system to
automatically recover from a specific error that occurs in
the CPU module of the standby system. (Manual
operation (turning off and on or resetting the system) is
not required to recover the system.)

Replacement/
addition of an
extension cable
(online)
The extension cable on the inactive side (ACTIVE LED is
turned off) between the redundant extension base units
can be replaced or added while the system is running.

Ethernet function Accesses the CPU module over Ethernet.
Using this function, the CPU module can connect to
MELSOFT products and GOTs, perform socket
communications, and transfer FTP files.
