Specifications
When the CPU Unit is in MONITOR or PROGRAM mode,
multiple program sections ("circuits") of the user program can
be edited together. This function is not supported for block
programming areas.
(With the CX-Programmer is used, multiple program sections
of the user program can be edited together. When a Pro-
gramming Console is used, the program can be edited in
mnemonics only.)
Overwrite protection: Set using DIP switch.
Copy protection: Password set using CX-Programmer or Pro-
gramming Consoles.
User-defined errors (i.e., user can define fatal errors and
non-fatal errors)
The FPD(269) instruction can be used to check the execution
time and logic of each programming block.
FAL and FALS instructions can be used with the CJ1-H and
CJ1M CPU Units to simulate errors.
Up to 20 errors are stored in the error log. Information
includes the error code, error details, and the time the error
occurred.
A CJ1-H or CJ1M CPU Unit can be set so that user-defined
FAL errors are not stored in the error log.
Built-in peripheral port: Programming Device (including Pro-
gramming Console) connections, Host Links, NT Links
Built-in RS-232C port: Programming Device (excluding Pro-
gramming Console) connections, Host Links, no-protocol
communications, NT Links, Serial Gateway (CompoWay/F
master)
Serial Communications Unit (sold separately): Protocol mac-
ros, Host Links, NT Links, Modbus-RTU slave, No-Protocol,
Serial Gateway (CompoWay/F master or Modbus master)
Provided on all models.
Accuracy: Ambient temperature
55°C
25°C
0°C
Note Used to store the time when power is turned ON and
when errors occur.
AC Power Supply Unit: 10 to 25 ms (not fixed)
DC Power Supply Unit PD025: 2 to 5 ms; PD022: 2 to 10 ms
0 to 10 ms (user-defined, default: 0 ms)
Note Not supported when the CJ1W-PD022 Power Supply
Unit is mounted.
Held Areas: Holding bits, contents of Data Memory and
Extended Data Memory, and status of the counter Comple-
tion Flags and present values.
Note If the IOM Hold Bit in the Auxiliary Area is turned ON,
and the PLC Setup is set to maintain the IOM Hold Bit
status when power to the PLC is turned ON, the con-
tents of the CIO Area, the Work Area, part of the Auxil-
iary Area, timer Completion Flag and PVs, Index
Registers, and the Data Registers will be saved for up
to 20 days.
FINS commands can be sent to a computer connected via
the Host Link System by executing Network Communications
Instructions from the PLC.
