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 Table 12.1.

1: CPU module error codes are classified into minor, moderate, major errors as shown below.
*
• Minor error: Errors that may allow the CPU module to continue the operation, e.g., battery error.
(Error code: 1300 to 10000)
• Moderate error: Errors that may cause the CPU module to stop the operation, e.g., WDT error.
(Error code: 1300 to 10000)
• Major error: Errors that may cause the CPU module to stop the operation, e.g., RAM error.
(Error code: 1000 to 1299)
Determine the error level, i.e. whether the operation can be continued or stopped, by referring to
"Operating Statuses of CPU" described in Section 12.3.3 to 12.3.9 "Error Code List"
