Function
Description
Program Error Detection
This function detects errors in programs.
Instruction Processing
Error Detection
This function detects an error when the given data value is invalid when executing an
instruction, or execution of instruction between tasks was attempted.
Indirect DM/EM BCD
Error Detection
This function detects an error when an indirect DM/EM address in BCD mode is not BCD.
Illegal Area Access Error This function detects an error when an attempt is made to access an illegal area with an
Detection
instruction operand.
No END Error Detection This function detects an error when there is no END instruction at the end of the program.
Self-
diagnosis
and
Restoration
Fatal Error
Detection
Task Error Detection
Differentiation Overflow
Error Detection
Invalid Instruction Error
Detection
This function detects an error when there are no tasks that can be executed in a cycle, there
is no program for a task, or the execution condition for an interrupt task was met but there is
no interrupt task with the specified number.
This function detects an error when too many differentiated instructions are entered or deleted
during online editing (131,072 times or more).
This function detects an error when an attempt is made to execute an instruction that is not
defined in the system.
User Program Area
This function detects an error when instruction data is stored after the last address in user
Overflow Error Detection program area.
Cycle Time Exceeded Error This function monitors the cycle time (10 to 40,000 ms) and stops the operation when the set
Detection
value is exceeded.
Fatal Error
Detection
(Continued from
previous page)
System FALS Error Detection
(User-defined Fatal Error)
Version Error Detection
Memory Card Transfer Error
Detection
This function generates a fatal (FALS) error when the user-defined conditions are met in
program.
This function detects an error when a user program includes a function that is not supported
by the current unit version.
This function detects an error when the automatic file transfer from Memory Card fails at
startup.
Simple Backup Function
This function collectively backs up the data in CPU Unit (user programs, parameters, and I/O
memory) and internal backup data in the I/O Units.
Unsolicited Communications
A function that allows the PLC to use Network Communications Instruction to send required
FINS commands to a computer connected via a Host Link
Maintenance ^{Remote Programming and Monitoring}
Host Link communications can be used for remote programming and remote monitoring
through a Controller Link, Ethernet, DeviceNet, or SYSMAC LINK Network. Communications
across network layers can be performed.
Controller Link or Ethernet : 8 layers
DeviceNet or SYSMAC LINK : 3 layers
Automatic Online Connection via
Network
Direct
Serial
Connection
This function enables automatically connecting to the PLC online when the CX-Programmer
is directly connected by a serial connection (peripheral (USB) port or serial port).
Via
This function enables connecting the CX-Programmer online to a PLC that is connected via an
Networks EtherNet/IP network.
Read Protection using Password
This function protects reading and displaying programs and tasks using passwords.
Write protection: Set using the DIP switch.
Read protection: Set a password using the CX-Programmer.
Security
FINS Write Protection
Unit Name Function
This function prohibits writing by using FINS commands sent over the network.
This function allows the users to give any names to the Units. Names are verified at online
connection to prevent wrong connection
Hardware ID Using Lot Numbers
This function sets operation protection by identifying hardware using the user programs
according to lot numbers stored in the Auxiliary Area.
