Error Error definition and causes
code
C040H • Sufficient data for the data length could
not be received.
• The remaining part of the message
divided at the TCP/IP level could not be
received.
C050H ASCII code data that cannot be converted
to binary code was received.
C051H • The number of read/write points from/to
the device of SLMP message is out of
the allowable range in the CPU module
(in units of words).
• The number of write points for the long
counter of SLMP message is not in two-
word units.
C052H The number of read/write points from/to
the device of SLMP message is out of the
allowable range in the CPU module (in
units of bits).
C053H The number of read/write points from/to
the random device of SLMP message is
out of the allowable range in the CPU
module (in units of bits).
C054H The number of read/write points from/to
the random device of SLMP message is
out of the allowable range in the CPU
module (in units of words, double words).
C055H The read/write size from/to the file data of
SLMP message is out of the allowable
range.
C056H The read/write request exceeds the largest
address.
C057H The request data length of the SLMP
message does not match the number of
data in the character (a part of text).
C058H The request data length of the SLMP
message after the ASCII/binary conversion
does not match with the number of data in
the character (a part of text).
C059H • The specified command and
subcommand of the SLMP message are
incorrect
• A function that is not supported by the
target device was executed.
C05AH The Ethernet-equipped module cannot
read/write data from/to the device specified
by the SLMP message.
C05BH The Ethernet-equipped module cannot
read/write data from/to the device specified
by the SLMP message.
C05CH • The received request data of the SLMP
message is incorrect.
• The setting value of the communication
setting when the iQSS function is
executed is out of range.
• When the iQSS function is executed, the
items of communication setting which
cannot be set on the target device are
set.
• When the iQSS function is executed, the
required setting items have not been set
to the target device.
Action
• Correct the data length of the communication data.
• Since there may be congestion of packets on the line, send the data again
from the external device after a random amount of time has passed.
Check if the ASCII code data that cannot be converted into binary code data
was sent from the external device.
Correct the number of read/write points and send the SLMP message to the
Ethernet-equipped module again.
Correct the number of read/write points and send the SLMP message to the
Ethernet-equipped module again.
Correct the number of read/write points and send the SLMP message to the
Ethernet-equipped module again.
Correct the number of read/write points and send the SLMP message to the
Ethernet-equipped module again.
Correct the read/write size and send the SLMP message to the Ethernet-
equipped module again.
• Correct the start address or the number of read/write points so that the
request does not exceed the largest address and send the data to the
Ethernet-equipped module again.
• If the access target and connection stations are modules of the MELSEC
iQ-R series, send the SLMP message again to the Ethernet-equipped
module using 003 and 002 of subcommands.
Check and correct the text or request data length, and send the SLMP
message to the Ethernet-equipped module again.
Check and correct the text or request data length, and send the SLMP
message to the Ethernet-equipped module again.
• Check that there are no errors in the specification of the command and
subcommand of the SLMP message.
• Check whether the function executed is supported by the target device.
• Check the version of the target device.
Correct the specification of the device to be read/written and send the SLMP
message to the Ethernet-equipped module again.
Correct the specification of the device to be read/written and send the SLMP
message to the Ethernet-equipped module again.
• Correct the request data and send the SLMP message to the Ethernet-
equipped module again.
• Correct the setting details of when the iQSS function is executed, and retry
the operation.
