Memory Card functions Automatically reading programs
(autoboot) from the Memory Card
when the power is turned ON. Possible
Program replacement during PLC
operation Possible
Memory Card storage data User program: Program file format
PC Setup and other parameters: Data file format
I/O memory: Data file format (binary), text format, CSV format
CPU Bus Unit data: Special format
Memory Card read/write method User program instructions, Programming Devices (including CX-Programmer
and Programming Console), Host Link computers, AR Area control bits, easy
backup operation
Filing Memory Card data can be handled as files.
Debugging Force-set/reset, differential monitoring, data tracing (scheduled, each cycle, or when instruction is executed)
Online editing One or more program blocks in user programs can be overwritten when CPU Unit is in PROGRAM or MONITOR
mode. This function is not supported for block program areas. With the CX-Programmer, more than one program
circuit can be edited at the same time.
Program protection Overwrite protection: Set using DIP switch.
Copy protection: Password set using CX-Programmer.
Error check User-defined errors (i.e., user can define fatal errors and non-fatal errors)
The FPD(269) instruction can be used to check execution time and logic of each programming circuit.
Error status can be simulated with the FAL and FALS instructions.
Error log Up to 20 errors are stored in error log. Information includes error code, error details, and time error occurred.
It is possible to set whether or not FAL errors are stored in the error log.
Serial communications Built-in peripheral port: Programming Device (e.g., CX-Programmer or Programming Console), Host Links, NT Links
Built-in RS-232C port: Programming Device (e.g., CX-Programmer), Host Links, no-protocol communications, NT
Links, Serial PLC Links
Serial Communications Unit (sold separately): Protocol macros, Host Links, NT Links
Clock Provided on all models. Accuracy:
±
1.5 min/mo. at 25
°
C.
Note: 1. The accuracy varies with the temperature.
2. Used to store time when power is turned ON and when errors occur.
Power OFF detection
time 10 to 25 ms (not fixed)
Power OFF detection
delay time 0 to 10 ms (user-defined, default: 0 ms)
Memory protection Held areas: User program, holding bits, Data Memory, and status of counter Completion Flags and present values.
Note: If the IOM Hold Bit in the Auxiliary Area is ON, and the PC Setup is set to maintain the IOM Hold Bit status
when power is turned ON, the contents of the CIO Area, Work Area, part of the Auxiliary Area, timer
Completion Flags and PVs, Index Registers, and Data Registers will be saved.
Sending commands to a
Host Link computer FINS commands can be sent to a computer connected via Host Link System by executing Network Communications
Instructions from PLC.
Remote programming
and monitoring Host Link communications can be used for remote programming and remote monitoring through a Controller Link
System or Ethernet network.
Three-level
communications Host Link communications can be used for remote programming and remote monitoring from devices on networks
up to two levels away (Controller Link Network, Ethernet Network, or other network).
Storing comments in
CPU Unit I/O comments can be stored in Memory Cards.
Program check Program checks are performed for items such as no END instruction and instruction errors. CX-Programmer can also
be used to check programs.
Control output signals RUN output: The internal contacts will turn ON (close) while the CPU Unit is operating. (Possible only with CJ1W-
PA205R Power Supply Unit.)
Battery life 5 years at 25
°
C (The battery life depends on the ambient operating temperature; 0.75 year min.)
(Battery Set: CJ1W-BAT01)
Note: Use a replacement battery for which no more than 2 years have expired since the date of manufacture.
Self-diagnostics CPU errors (watchdog timer), I/O bus errors, memory errors, and battery errors
Other functions Storage of the number of times power has been interrupted. (Stored in A514.)
