The minimum cycle time setting can be changed in MONITOR mode.

The cycle time is monitored.
(0.01 to 40,000 ms; Unit: 0.01 ms)

Instructions with long execution times can be executed over multiple cycles to prevent
fluctuations in the cycle time.

The input response times can be set for Basic I/O Units. The response time can be
increased to reduce the effects of chattering and noise at input contacts. The response
time can be decreased to enable detecting shorter input pulses.

All of the outputs on Basic I/O Units can be turned OFF when an error occurs in RUN or
MONITOR mode.

Alarm information can be read from Basic I/O Units and the number of Units recognized
can be read.

changed, to reserve words, and to set words.

The status of I/O memory can be held when the operating mode is changed or power is
turned ON. The forced-set/reset status can be held when the operating mode is changed
or power is turned ON.

Bus for communications with various kinds of Support Software running on a personal
computer. High-speed communications are supported.

Host Link commands or FINS commands placed between Host Link headers and terminators
can be sent from a host computer or PT to read/write I/O memory, read/control the operating
mode, and perform other operations for PLC.

I/O instructions for communications ports (such as TXD/RXD instructions) can be used for
data transfer with peripheral devices such as bar code readers and printers.

I/O memory in the PLC can be allocated and directly linked to various PT functions, including
status control areas, status notification areas, touch switches, lamps, memory tables, and
other objects.

Bus for communications with various kinds of Support Software running on a personal
computer. High-speed communications are supported.

Tasks can be executed at a specified interval (minimum of 0.2 ms or 0.1 ms *, Unit: 0.1 ms).
* When High-speed interrupt function is used.

A task can be executed when interrupts are requested from a Special I/O Unit or a CPU Bus
Unit.

Clock data is stored in memory.
Accuracy (Accuracy depends on the temperature.)
Ambient temperature of 55°C: −3.5 to +0.5 min error per month
Ambient temperature of 25°C: −1.5 to +1.5 min error per month
Ambient temperature of 0°C: −3 to +1 min error per month

The last time a fatal error occurred or the last time the operating mode was changed to
PROGRAM mode is stored.

Holding Area data, DM Area data, EM Area data, Counter Completion Flags, and counter
present values are held even when power is turned OFF. CIO Area, Work Area, some Auxiliary
Area data, and Timer Completion Flags, timer present values, index registers, and data
registers can be protected by turning ON the IOM Hold Bit in the Auxiliary Area, and by also
setting the IOM Hold Bit to “Hold” in the PLC Setup.

The detection time for power interruptions can be set.
AC power supply: 10 to 25 ms (variable)
DC power supply: 2 to 5 ms (CJ1W-PD022) or 2 to 20 ms (CJ1W-PD025)

The detection of power interruptions can be delayed: 0 to 10 ms
(Not supported by the CJ1W-PD022.)

The program can be changed during operation (in MONITOR or PROGRAM mode), except for
block programming areas.

Specified bits can be set or reset.
Force-set/reset to the EM Area is enabled by specifying a start bank in parameter setting.
(unit version 1.2 or higher)

The specified I/O memory data can be stored in the trace memory in the CPU Unit. The
triggers can be set.

• The trace data can be uploaded during data tracing using CX-Programmer, which enables
continuously logging the data by constantly uploading the trace data (trace data uploading
during tracing).

• Data tracing can be automatically started when operation is started (i.e., when the operating
mode is changed from PROGRAM mode to MONITOR or RUN mode).

The programs can be checked for items such as no END instruction and FALS/FAL errors at
startup.

added based on the same functionality as CJ2H-CPU6@-EIP unit version 1.0.

Function Support by Unit Version

Unit Version 1.2 or Later

CX-Programmer version 8.3 or higher must be used to enable using the functions added for unit version 1.2.

EM force-set/reset function Supported. Not supported.

Note: User programs that use functions of CJ2H CPU Units with unit version 1.2 or later cannot be used with CJ2H CPU Units with unit version

1.1 or earlier. If an attempt is made to transfer a program that uses any of these functions from the CX-Programmer to a CPU Unit with unit
version 1.1 or earlier , an error will be displayed and it will not be possible to download to the CPU Unit.

Unit Version 1.1 or Later

CX-Programmer version 8.1 or higher must be used to enable using the functions added for unit version 1.1.
Note: Although the product of unit version 1.0 does not exist for the CJ2H CPU unit (CJ2H-CPU6@), it describes here assuming that the functions

are added with unit version 1.1 to the unit version 1.0 functions as well as CJ2H-CPU6@-EIP.
