Module diagnostics
The Module Diagnostic function diagnoses the operating status of each module (module status, existence of an error, or error
logs, etc.).
It displays an error occurred, detailed status, causes, and corrective actions, so information necessary for troubleshooting can
be checked. In addition, the error part on the parameter can be identified by selecting the error and click the [Error Jump]
button.
In the [Module Information List] tab, the current LED information or switch information of the corresponding module can be
checked.
