Error Log

Error log records errors occurring in the controller. The most recent 1,000 errors are recorded. The data is saved in data storage memory.

The error log is regularly updated.

Two or more types of errors may occur simultaneously, but what appears as an error message is only one of those errors. Checking the error log to see other errors that occurred simultaneously or checking the error log in conjunction with the operation log helps in pursuing the cause of errors.

From the menu bar, click View, point to Log view, select Error.
