A
2225H Parameter error The CPU module model set to the project using the
engineering tool differs from that of the CPU module
actually mounted.
Correct the CPU module model set to the project in
accordance with the CPU module actually mounted.
2240H Parameter error (module) In the multiple CPU system, the I/O module or intelligent
function module controlled by another CPU module is
specified in the module parameters.
Check the detailed information (parameter information),
and correct the parameter setting corresponding to the
displayed number. If the same error code is displayed
again, the possible cause is a hardware failure of the data
memory in the CPU module or the module (I/O module or
intelligent function module) connected. Please consult
your local Mitsubishi representative.
2241H Parameter error (module) • The I/O numbers set in the system parameters differ
from those of the module actually mounted.
• The target module is not mounted on the slot where the
system parameters and module parameters are set.
• The module type set in parameter differs from that of
the module actually mounted.
• Check if the system configuration displayed on the
system monitor window of the engineering tool match
the actual system configuration.
• Check the detailed information (parameter information),
and correct the parameter setting corresponding to the
displayed number. If the same error code is displayed
again, the possible cause is a hardware failure of the
data memory in the CPU module or the module (I/O
module or intelligent function module) connected.
Please consult your local Mitsubishi representative.
2242H Parameter error (module) The intelligent function module has detected a module
parameter error.
Check the detailed information (system configuration
information), and check the module corresponding to the
displayed I/O number. If the same error code is displayed
again, the possible cause is a hardware failure of the data
memory in the CPU module or the intelligent function
module connected. Please consult your local Mitsubishi
representative.
2280H Parameter error (refresh) The refresh setting is not set correctly. Check the detailed information (parameter information),
and correct the parameter setting corresponding to the
displayed number so that the data are refreshed within the
specified device range.
2281H Parameter error (refresh) A device that cannot be used as a refresh device is
specified.
Check the detailed information (parameter information),
and correct the parameter setting corresponding to the
displayed number.
2282H Parameter error (refresh) The number of specified refresh points is invalid. Check the detailed information (parameter information),
and correct the parameter setting corresponding to the
displayed number.
22E0H Parameter verification
error
• In the multiple CPU system, the system parameter
settings of the host CPU module differ from those of
other CPU modules.
• In the multiple CPU system, the system parameter
settings are overwritten only to the host CPU module,
and the settings differ from those of other CPU
modules.
• Check the detailed information (parameter information),
and correct the system parameter settings
corresponding to the displayed number for the CPU
No.2 and later. The settings need to be the same
between all the CPU modules. (The module
synchronization setting and fixed scan communication
setting need to be the same between the CPU modules
that use these functions.)
• When the system parameter settings are changed,
update the settings of all the CPU modules connected.
(The system parameter settings must be same in all the
CPU modules.)
2300H Security key
authentication error
The security key set to the program does not match the
one registered to the CPU module.
Check and correct the security key setting.
2301H Security key
authentication error
The security key is set to the program, but it is not
registered to the CPU module.
Check and correct the security key setting.
2302H Security key
authentication error
• The security key set to the file is corrupted and does not
match the one registered to the CPU module.
• The security key registered to the CPU module is
corrupted and does not match the one set to the file.
Write the file to the CPU module again. 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.
2400H Module verification error • The I/O module information at power-on differs from the
information of modules actually mounted.
• The I/O module or intelligent function module is not
mounted properly or was removed during operation.
Check the detailed information (system configuration
information), and check the module corresponding to the
displayed slot number.
2401H Module verification error A CPU module, I/O module, or intelligent function module
was mounted on the base unit during operation.
• Check the detailed information (system configuration
information), and check the module corresponding to
the displayed slot number.
• Do not mount a CPU module, I/O module, nor intelligent
function module during operation.
