36.4 List of Error Codes
Error details and cause
• 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.
• A device that cannot be used as a
refresh device is specified.
• The number of specified refresh
points is invalid.
• The total number of refresh points
exceeded the maximum limit.
• 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.
• The security key set to the program
does not match the one registered to
the CPU module (or cassette).
• The security key is set to the program,
but it is not registered to the CPU
module (or cassette).
• 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.
• The security key is registered to the
CPU module and cassette.
Stop/ Action
continue
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.)
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.
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.)
Stop • Check and correct the security key
setting.
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.
Stop • Check and correct the security key
setting.
