Appendix 1.5 Error Code For Slmp (Mc Protocol) Communication - Mitsubishi Electric MELSEC Q Series User Manual

Appendix 1.5
The following table provides the descriptions and corrective actions for error codes sent from a C Controller module to
external devices at the error occurrence related to the SLMP (MC protocol) communication.
Error code
An error detected by the C Controller module for the
4000 to 4FFF function other than the SLMP (MC protocol)
H H
communication function
The number of write/read points is outside the allowable
C051 to C054
H H
range.
C056 The read/write request exceeds the maximum address.
H
Incorrect specification of the command (subcommand)
C059 Inapplicable command (subcommand) for C Controller
H
module
The C Controller module cannot read/write data from/to
C05B
H
the specified device.
Incorrect request (For example, a request for data read/
C05C
H
write in bit units has been issued to a word device.)
This request cannot be executed to the target CPU
C05F
H
module.
Incorrect request (For example, an incorrect
C060
H
specification on data for a bit device.)
The request data length does not match with the
C061
H
number of data in the character.
ASCII request message was received when the
C06F
H
communication data code setting was binary.
C070 The device memory is extended for the target station.
H
Data that cannot be processed on the CPU module was
C0B5
H
specified.
Error code for SLMP (MC protocol) communication
Error description Corrective action
Refer to the C Controller Module User's Manual and check the corrective action.
Correct the number of read/write points and send the data to the C Controller module
again.
Correct the start address or the number of read/write points by making sure that the
request does not exceed the largest address, and send the data to the C Controller
module again.
Correct the request details.
Send a command (subcommand) that can be used on the C Controller module.
Check the write/read command.
Correct the request and send it to the C Controller module again.
(A correction such as changing the subcommand)
Correct the network number, personal computer number, request target module I/O
number, or request target module station number.
Correct the request and send it to the C Controller module again.
(A correction such as correcting data)
Check and correct the text or requested data length of the header. Then send the data
to the C Controller module again.
Send a request message corresponds to the communication data code setting.
Change the communication data code setting corresponds to the request message.
Read/write data without extending the device memory.
Correct the request.
Cancel the current request.
