1 Overview and Specifications
Description
Holding Area data, DM Area data, Counter Completion Flags, and Counter
Present Values are held even when power is turned OFF.
This function is valid only when an optional battery is mounted.
The number of times power has been interrupted is counted.
The program can be changed during operation in MONITOR mode or PRO-
GRAM mode.
Specified bits can be set or reset.
ON/OFF changes in specified bits can be monitored.
The location and task number where execution stopped for a program error is
recorded.
The programs can be checked for items such as no END instruction and
FALS/FAL errors at startup.
Details and the time of occurance of error codes predefined by the CPU Unit
are stored.
CPU Unit WDT errors are detected.
Errors can be generated for user-specified conditions:Non-fatal errors (FAL)
and fatal errors (FALS).
The built-in outputs, Expansion I/O Unit outputs, and Expansion Unit outputs
are turned OFF.
This function generates a non-fatal (FAL) error when the user-defined condi-
tions are met in program.
This function detects when data in the backup memory (built-in EEPROM) that
stores the ladder program is corrupted.
This function detects setting errors in the PLC Setup.
This function detects when the Option Board is malfunctioning or discon-
nected.
This function detects when the battery voltage is low or the battery is discon-
nected.
* This function is valid only when a battery is mounted and the Do not detect
battery error Check Box is cleared in the PLC Setup.
This function detects built-in analog I/O errors.
This function detects errors that occur in memory of the CPU Unit.
This function detects errors that occur during data transfer between the CPU
Unit and another Unit.
This function detects when more than the maximum number of CP1W Expan-
sion I/O Units and Expansion Units are connected to the PLC.
This function detects when there is an error in the program.
See the following for details.
This function detects an error when the given data value is invalid when exe-
cuting an instruction, or execution of instruction between tasks was attempted.
This function detects an error when an indirect DM/EM address in BCD mode
is not BCD.
This function detects an error when an attempt is made to access an illegal
area with an instruction operand.
This function detects an error when there is no END instruction at the end of
the program.
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 instruc-
tion that is not defined in the system.
This function detects an error when instruction data is stored after the last
address in user program area.
This function monitors the cycle time (10 to 1,000 ms) and stops the operation
when the set value is exceeded.
This function generates a fatal (FALS) error when the user-defined conditions
are met in program.
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).
This function protects reading and displaying programs using passwords.
Read protection: Set a password using the CX-Programmer.
* Overwrite protection function not included.
This function prohibits writing by using FINS commands sent over the network.
