3401H • Data that cannot be converted by
using the data conversion instruction
was input.
3402H • The operation was performed with the
invalid data (-0, denormalized
number, NaN (not a number), or ).
3403H • An overflow has occurred during the
operation.
3404H • A string that is not supported in the
instruction was specified.
3405H • The input data was out of range.
3406H • The operation result is out of the
output range. (The operation result of
the instruction that concatenate
character strings exceeded the
allowable number of characters.)
3420H • The link direct device, module access
device, or CPU buffer memory access
device is specified for both (s) and (d)
used in the BMOV instruction.

3421H Operation error • When writing data to the data memory
by using the SP.DEVST instruction,
the number of writes per day
exceeded the number set in SD771.
• The value set in SD771 is out of
range.
Stop/
continue
• Check the detailed information
(error location information) of the
error by executing module
diagnostics using the engineering
tool, display the error program
(step) by clicking the [Error Jump]
button, and check if the
SP.DEVST instruction is used
correctly in the program.
• Execute the SP.DEVST instruction
again on another day, or change
the value in SD771.
• Set the value in SD771 within the
settable range.

3422H Operation error • The structure of the PID control
instruction is incorrect.
Stop/

3423H Operation error • The size of data to be sent/received
by the socket communications
instruction exceeds the allowable
range.
Stop/
continue
• Check and change the send data
size of the CPU module or the
external device.
• 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.
