Function
Description
Communications
−
Peripheral (USB)
Port
Peripheral Bus
Bus for communications with various kinds of Support Software running on a personal
computer. High-speed communications are supported.
Serial Port
−
Host Link (SYSWAY) Communications
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.
No-protocol Communications
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.
NT Link Communications
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.
Peripheral Bus
Bus for communications with various kinds of Support Software running on a personal
computer. High-speed communications are supported.
Serial Gateway
This gateway enables receiving and automatically converting FINS to the CompoWay/F.
EtherNet/IP Port
100Base-TX/10Base-T
Protocols: TCP/IP, UDP, ARP, ICMP (ping only), BOOTP
Applications: FINS, CIP, POP3, SMTP, SNTP, DNS (Client), FTP (Server)
CIP
Communications
Service
Tag Data Links
Programless cyclic data exchanges with the devices on the EtherNet/IP network.
Message Communications
Any CIP commands can be received from the devices on the EtherNet/IP network.
FINS
Communications
Service
Message Communications
Any FINS commands can be transferred with the devices on the EtherNet/IP network.
Interrupt
Scheduled Interrupts
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.
Power OFF Interrupts
A task can be executed when CPU Unit's power turns OFF.
I/O Interrupt Tasks
A task can be executed when an input signal is input to an Interrupt Input Unit.
External Interrupt Tasks
A task can be executed when interrupts are requested from a Special I/O Unit or a CPU Bus
Unit.
High-speed Interrupt Function
Improves performance for executing interrupt tasks with certain restrictions.
Clock
Clock Function
Cock 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
Operation Start Time Storage
The time when operating mode was last changed to RUN mode or MONITOR mode is stored.
Operation Stop Time Storage
The last time a fatal error occurred or the last time the operating mode was changed to
PROGRAM mode is stored.
Startup Time Storage
The time when the power was turned ON is stored.
Power Interruption Time Storage
The time when the power is turned OFF is stored.
Total Power ON Time Calculation
The total time that the PLC has been ON is stored in increments of 10 hours.
Power ON Clock Data Storage
A history of the times when the power was turned ON is stored.
User Program Overwritten Time Storage
The time that the user program was last overwritten is stored.
Parameter Date Storage
The time when the Parameter Area was overwritten is stored.
Power
Supply
Management
Memory Protection
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.
Power OFF Detection Time Setting
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)
Power OFF Detection Delay Time
The detection of power interruptions can be delayed: 0 to 10 ms
(Not supported by the CJ1W-PD022.)
Number of Power Interruptions Counter
The number of times power has been interrupted is counted.
Function Blocks
Standard programming can be encapsulated as function blocks.
Languages in Function Block Definitions
Ladder programming or structured text
Debugging
Online Editing
The program can be changed during operation (in MONITOR or PROGRAM mode), except for
block programming areas.
Force-Set/Reset
Specified bits can be set or reset.
Differentiate Monitoring
ON/OFF changes in specified bits can be monitored.
Data Tracing
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).
Storing Location of Error when an Error Occurs
The location and task number where execution stopped for a program error is recorded.
Program Check
The programs can be checked for items such as no END instruction and FALS/FAL errors at
startup.
