2101H Memory error • An extended SRAM cassette is
inserted or removed while the
programmable controller is powered
on.
Stop • Do not insert or remove an
extended SRAM cassette during
operation.
• Check the mounting status of the
CPU module of the extended
SRAM cassette. If the same error
code is displayed again, the
possible cause is a hardware
failure of the extended SRAM
cassette. Please consult your local
Mitsubishi representative.

information
Always
2102H Memory error • An error has been detected in the
inserted extended SRAM cassette.
Stop • Check the mounting status of the
CPU module of the extended
SRAM cassette. If the same error
code is displayed again, the
possible cause is a hardware
failure of the extended SRAM
cassette or CPU module. Please
consult your local Mitsubishi
representative.

information
Always
2103H Memory error • An unsupported extended SRAM
cassette is mounted.
Stop • Replace the extended SRAM
cassette with the one supported
by the CPU module.

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

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.

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.

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
u
s
ing 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. Please consult your local
Mitsubishi representative.

(after the firmware update) of the CPU
module, a program file of which file
structure is not supported by the new
version of the firmware or the
operation mode of the CPU module
has been written.
