36 ERROR CODES
36.4 List of Error Codes
2226H Parameter error • The SFC setting in the CPU
parameters is incorrect. (Block 0 was
set to start automatically, however,
block 0 does not exist.)
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.

2227H Parameter error • The execution type of the SFC
program set in the CPU parameter
program settings is other than the
scan execution type.
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.

2228H Parameter error • The memory area set by the
parameter cannot be secured.
Stop • Check the firmware version of the
CPU module and use a supported
product. Then, write parameters
again.

RESET, at
STOP  RUN
state
2240H Parameter error
(module)
• In a multiple CPU system, the I/O
module or intelligent function module
controlled by another CPU module is
specified in the module parameters.
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. 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.
Stop • 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) of the
error by executing module
diagnostics using the engineering
tool 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.
Stop • Check the detailed information
(system configuration information)
of the error by executing module
diagnostics using the engineering
tool, 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.
