36.4 List of Error Codes
Error details and cause
• Division where the divisor is zero was
performed.
• Data that cannot be converted by
using the data conversion instruction
was input.
• The operation was performed with the
invalid data (-0, denormalized
number, NaN (not a number), or ).
• An overflow has occurred during the
operation.
• A string that is not supported in the
instruction was specified.
• The input data was out of range.
• 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.)
• 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.
• 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.
• The structure of the PID control
instruction is incorrect.
• The size of data to be sent/received
by the socket communications
instruction exceeds the allowable
range.
• A second SFC program was started
with an instruction while an SFC
program was running.
Stop/ Action
continue
Stop/ • Check the detailed information
continue (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 correct the program.
Stop/ • Check the detailed information
continue (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.
Stop/ • Check the detailed information
continue (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 correct the PID control
instruction structure.
Stop/ • Check and change the send data
continue 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.
Stop/ • Check the detailed information
continue (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 the SFC
program execution status.
