Appendix 1 Error Codes
2280H Parameter error
(refresh)
• The refresh setting is not set
correctly. (Data were refreshed
exceeding the file register
capacity.)
• The refresh settings (number of
points) are different from those of
other numbered CPU modules.
Stop • Check the detailed information
(parameter information) of the error by
executing module diagnostics using
the engineering tool, and correct the
parameter setting corresponding to the
displayed number so that the data are
refreshed within the specified device
range. (Take the following actions:
increase the number of file register
points, create a file register file having
a capacity for all of the target data to be
refreshed, or reduce the refresh device
range.)
• Rewrite the refresh settings (number of
points) in the CPU parameters for all
the CPU modules. (Use the same
number of points in the refresh settings
for all the CPU modules.)

2281H Parameter error
(refresh)
• A device that cannot be used as a
refresh device is specified.
Stop • Check the detailed information
(parameter information) of the error by
executing module diagnostics using
the engineering tool and correct the
parameter setting corresponding to the
displayed number.

state
2282H • The number of specified refresh
points is invalid.
2283H • The total number of refresh points
exceeded the maximum limit.
22E0H Parameter
verification error
• In a multiple CPU system, the
system parameter settings of the
host CPU module differ from those
of other CPU modules.
• In a 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.
Stop • Check the detailed information
(parameter information) of the error by
executing module diagnostics using
the engineering tool, 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 among 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 (or
cassette).
Stop • Check and correct the security key
setting.

information
At power-on,

2301H • The security key is set to the
program, but it is not registered to
the CPU module (or cassette).
2
302H 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.
Stop • 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.
