22. TROUBLESHOOTING
22.3.1 Error Codes
There are errors that is detected by the self-diagnostics function of the CPU module, and
that is detected while communicating with the CPU module.
The table below shows the link between the type of error detection, the point of error
detection and the error codes.
*1: The error codes of the CPU module are categorizes according to minor errors, moderate
errors and major errors.
22.3.2 Procedure to read an error code
When an error occurs, error codes and error messages can be read with the peripheral
devices.
For details on the setting method for each function, refer to the GX Developer Operating
Manual or SW IVD-GPPQ Operating Manual (Offline).

Minor error: Errors that CPU module such as a battery error continues the operation
(Error code: 1300 to 9999)
Moderate error: Errors that CPU module such as a WDT error stops the operation
(Error code: 1300 to 9999)
Minor error: Errors that CPU module such as a RAM error stops the operation
(Error code: 1000 to 1299)
"The error that the QnACPU continues operation" and "the error that QnACPU stops
operation" are determined by "CPU operation status" of the error code list.
