SLMP function error code
3E frame
■Error codes returned to target device during data communication
Error codes stored when communication ends in error during SLMP (3E frame) are as provided in the following table.
Error code
Error details and causes
(Hexadecimal)
4000H to 4FFFH
Errors detected by CPU module.
(Errors that occurred in other than SLMP communication
function)
C050H
When the communication data code is set to "ASCII", ASCII code
data which cannot be converted to binary is received.
C051H
Maximum number of bit devices for which data can be read/
written all at once is outside the allowable range.
C052H
Maximum number of word devices for which data can be read/
written all at once is outside the allowable range.
C053H
Maximum number of bit devices for which data can be random
read/written all at once is outside the allowable range.
C054H
Maximum number of word devices for which data can be random
read/written all at once is outside the allowable range.
C056H
Read or write request exceeds maximum address.
C058H
Request data length after ASCII-to-binary conversion does not
match the number of data in the character section (part of text).
C059H
• Error in command or subcommand specification.
• There is a command or subcommand that cannot be used by
the CPU module.
C05BH
CPU module cannot read or write from/to specified device.
C05CH
Error in request contents. (Reading or writing by bit unit for word
device, etc.)
C05FH
There is a request that cannot be executed for the target CPU
module.
C060H
Error in request contents. (Error in specification of data for bit
device, etc.)
C061H
Request data length does not match the number of data in the
character section (part of text).
C06FH
When the communication data code is set to "Binary", a request
message of ASCII is received. (Error history of this error code is
registered but no error response is sent.)
C0D8H
The number of specified blocks exceeds the range.
C200H
Error in remote password.
C201H
Locked status of the remote password of the port which is used
for communication.
C204H
Different device requested remote password to be unlocked.
C810H
Error in remote password. (Authentication failure count is 9 or
less.)
C815H
Error in remote password. (Authentication failure count is 10.)
C816H
Remote password authentication is locked out.

13.4 Error Codes
Action
Refer to MELSEC iQ-F FX5 User's Manual (Application) and take
appropriate measures.
• For communication, set to "Binary" in the communication data code
and restart the CPU module.
• Correct the send data from the target device and send it.
Correct number of bit devices that can be read or written all at once,
and send to CPU module again.
Correct number of word devices that can read or write all at once, and
send to CPU module again.
Correct number of bit devices that can be random read or written all at
once, and send to CPU module again.
Correct number of word devices that can be random read or written all
at once, and send to CPU module again.
Correct starting address or number of read and write points, and send
to CPU module again. (Be careful not to exceed the maximum
address.)
After reviewing and correcting content of text or length of request data
in the header, send to CPU module again.
• Reconsider request contents.
• Send command or subcommand that can be used by the CPU
module.
Reconsider device to read or write.
Correct request content, and send to CPU module again.
(Subcommand correction, etc.)
• Correct network No., request station No., request destination
module I/O No., or request destination module station No.
• Correct contents of write request and/or read request.
Correct request content, and send to CPU module again. (Data
correction, etc.)
After reconsidering and correcting content of text or length of request
data in the header, send to CPU module again.
• Sent a request message which matches the setting of the
communication data code.
• Change the communication data code to match the request
message.
Correct the specified value of for the number of blocks.
Correct remote password, and re-execute remote password lock and
unlock.
Unlock the remote password before data communication.
Request remote password lock from device that requested unlock of
remote password.
Correct remote password, and re-execute remote password unlock.
Re-execute remote password unlock after the specified time elapses.
Re-execute remote password unlock after the specified time elapses.
