APPENDIX 3 Self-diagnosis error code
Multiple CPU related errors are stored in the CPU shared memory "self CPU operation
information area (1H to 1CH)" of each module and self diagnostic error information
(SD0 to SD26) of the special register (SD) as the self diagnostic errors.
Error codes (1000 to 9999) of Multiple CPU related errors are common to each CPU
module.
The error code (10000 to 10999) is stored as required at Motion CPU-specific error
occurrence.
Confirm the error codes and contents by "Motion error history" on Motion CPU error
batch monitor of MT Developer and remove the error cause if an error occurs.
Confirm operation status and error occurrence of each CPU used in the Multiple CPU
system by PLC diagnosis of GX Developer.
