Appendix 1
Error Codes
The CPU module stores the corresponding error code in the special register (SD) upon detection of an error by the self-
diagnostic function. If an error occurs when the data communications are requested from the engineering tool, intelligent
function module, or network system connected, the CPU module returns the corresponding error code to the request source.
The error details and cause can be identified by checking the error code. The error code can be checked in either of the
following ways:
• Module diagnostics by the engineering tool (
MELSEC iQ-R CPU Module User's Manual (Startup))
• Special register (SD0 (Latest self-diagnostics error code), SD10 to SD25 (Self-diagnostic error number)) (
List of Special Register Areas)
This section describes errors that may occur in the CPU module and actions to be taken for the errors.
Error code system
All error codes are given in hexadecimal format (4 digits) (16-bit unsigned integer). The type of error includes the error, which
is detected through the self-diagnostic function of each module, and the common error, which is detected during data
communications between modules. The following table lists the error detection type and the error code ranges.
Error detection type
