Appendix 3
The CPU module stores error code in special register (SD) upon detection of an error using the self-diagnostics function. 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 of engineering tool (MELSEC iQ-F FX5 User's Manual (Startup))
• Special register (SD0 (latest self-diagnostics error code), SD10 to SD25 (self-diagnostics error code)) (Page 348
Special Register List)
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 following table lists the error detection
type and the error code ranges.
Error detection type
Detection by the self-diagnostics function of each module
Detected during communication between CPU modules
Detailed information
Upon detection of error through self-diagnostics function, the detailed information of the error cause is stored all together. The
following detailed information is added to each error code (up to two types of information are stored for each error code. The
types differ depending on error code.) Detailed information 1 to 2 of the latest error code(s) can be checked with special
register (SD).
