Appendix 1 Error Codes
723
A
2121H Memory card
error
• An error has been detected in the
memory card.
Stop/
continue
• Format the memory card, re-insert the
memory card, or replace the memory
card. If the same error code is
displayed again, the possible cause is
a hardware failure of the CPU module.
Please consult your local Mitsubishi
representative.
Drive/file
information
Always
2122H Memory card
error
• The CPU module did not start
because the memory card was not
restored during the startup
processing.
Stop • Reset the CPU module. If the same
error code is displayed again, the
possible cause is a hardware failure of
the memory card. Replace the memory
card.
Drive/file
information
At power-on,
at RESET
2150H Initial
processing time
error
• Since the initial processing takes
time, the host CPU in a multiple
CPU system cannot respond to
communication requests from
other CPU modules in initial
communications. (Other CPU
modules cannot start up.)
Stop Take the following action to shorten the
initial processing time.
• Check and correct the restoration
setting and the number of files to be
restored if the automatic data
restoration function is being executed.
At power-on,
at RESET
2160H IP address
duplication error
• Overlapping IP addresses have
been detected.
Stop • Check and correct the IP addresses. Always
2180H Invalid file • An invalid file has been detected. Stop • Check the detailed information (drive/
file information) of the error by
executing module diagnostics using
the engineering tool, select the correct
file name, and write the specified file to
the CPU module. If the same error
code is displayed again, the possible
cause is a hardware failure of the CPU
module or module (SIL2 function
module or safety function module)
connected. Please consult your local
Mitsubishi representative.
Drive/file
information
At power-on,
at RESET, at
STOP RUN
state
2181H Invalid file • Since the firmware update or
restoration (after the firmware
update) of the CPU module has
been performed, the CPU module
with a new firmware version no
longer supports a program file in
the CPU module.
Stop • After reading program files from the
programmable controller, format the
memory and write the program files.
Then, reset the CPU module and run it
again.
Drive/file
information
At power-on,
at RESET
2182H Invalid file • The program file is incorrect. Or,
the program file is not correctly
written.
Stop • Write the program file to the CPU built-
in memory again.
Drive/file
information
At power-on,
at RESET
21A0H File
specification
error
• The file specified in the CPU
parameters does not exist.
• The memory card is disabled by
tuning on SM606 (SD memory
card forced disable instruction).
• The file register file does not exist
in the specified memory when the
file register setting is set to "Use
Common File Register in All
Programs" and the file capacity is
not set in the CPU parameters
("File Setting").
• The file specified in the memory
c
ard parameters ("Boot Setting")
does not exist in the memory card.
Stop • Turn off SM606. (Cancel the disabled
state.)
• Check the detailed information (drive/
file information) of the error by
executing module diagnostics using
the engineering tool, select the correct
file name, and write the specified file to
the CPU module. If the same error
code is displayed again, the possible
cause is a hardware failure of the
device/label memory in the CPU
module, memory card, or module (SIL2
function module or safety function
module) connected. Please consult
your local Mitsubishi representative.
