Error Error name Error details and cause
code
2040H CPU module • The number of CPU modules set in
configuration the system parameters ("I/O
error Assignment Setting") differs from the
number of CPU modules actually
mounted.
• The CPU module is mounted on the
slot different from the one specified in
the system parameters (I/O
assignment setting).
• Two or more Safety CPUs are
mounted.
2041H CPU module • The CPU module is not mounted on
configuration the slot that is set for the CPU module
error in the system parameters ("I/O
Assignment Setting").
• The CPU module is mounted on the
slot that is set for empty in the system
parameters ("I/O Assignment
Setting").
• An I/O module or intelligent function
module is mounted between the CPU
modules.
• Arrangement of CPU modules
mounted is not appropriate to
configure a multiple CPU system.
2043H CPU module • The CPU module is mounted on the
configuration inapplicable slot.
error
2044H CPU module • The host CPU No. set in the system
configuration parameters ("I/O Assignment
error Setting") differs from the one
determined by the mounting position
of the CPU module.
2046H CPU module • Another CPU module was accessed,
configuration but there was no response.
error
2050H CPU module • An unsupported CPU module is
configuration mounted.
error
2051H CPU module • A CPU module that does not support
configuration the online module change (direct
error change) function is used in a multiple
CPU system.
Stop/ Action

Stop • Correctly set the number of CPU
modules (including the empty
setting) in the system parameters
in accordance with the number of
CPU modules actually mounted.
• Correctly set the system
parameters so that the setting and
actual CPU module mounting
status will be the same.
• Mount only one Safety CPU.
Stop • Check and correct the I/O
assignment setting in the system
parameters.
• Correctly set the number of CPU
modules (including the empty
setting) in the system parameters
in accordance with the number of
CPU modules actually mounted.
• Remove the I/O module or
intelligent function module
mounted between the CPU
modules.
Stop • Mount the CPU module on the
applicable slot (CPU slot or I/O
slot 0 to 6).
• Remove the CPU module from the
inapplicable slot.
Stop • Re-set the host CPU No. in the
system parameters in accordance
with the mounting position of the
CPU module.
Stop • Check and correct the I/O
assignment setting in the system
parameters.
• Take measures to reduce noise.
• Reset the CPU module and run it
again. If the same error code is
displayed again, the possible
cause is a hardware failure of
another CPU module. Please
consult your local Mitsubishi
representative.
Stop • Remove the unsupported CPU
module. If all the CPU modules
are supported, the possible cause
is a hardware failure of the CPU
module or base unit. Please
consult your local Mitsubishi
representative.
Stop • Refer to the MELSEC iQ-R Online
Module Change Manual, and
correct the system configuration.
• To disable the online module
change (direct change) function,
set "Direct change setting" to
"Disable" in the CPU parameters.
If the same error code is displayed
again, the possible cause is a
hardware failure of the CPU
module or base unit. Please
consult your local Mitsubishi
representative.
