12.3 Error Code List

The Q series CPU module uses the self diagnostics function to display error information
(on the LED) and stores the information into the special relay SM and special register SD,
when an error occurs in the following situations:
• When the programmable controller is powered ON.
• When the CPU module is switched from STOP to RUN.
• While the CPU module is running.
If an error occurs when a communication request is issued from GX Developer, intelligent
function module or network system to the CPU module, the CPU module returns the error
code (4000

12.3.1 Error codes

Errors are detected by the self diagnostic function of the CPU module or detected during
communication with the CPU module.
The relation between the error detection pattern, error detection location and error code is
shown in Table12.4.

* 1: CPU module error codes are classified into minor, moderate, major errors as shown below.
• Minor error:
• Moderate error: Errors that may cause the CPU module to stop the operation, e.g., WDT error.
• Major error:
* 2: When detected an error code without being noted in the reference table, please contact your local
Mitsubishi representive.
