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 the following table.
"Errors that may allow the CPU module to continue the operation" and "Errors that may cause the CPU module to
stop the operation" can be distinguished using "Operating Statuses of CPU" of Section 12.3.3 to 12.3.8 Error
code list.

* 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.
•Moderate error: Errors that may cause the CPU module to stop the operation, e.g., WDT error.
•Major error: Errors that may cause the CPU module to stop the operation, e.g., RAM error.
