Chapter 8 Logging
8.3 Detailed description of log types
8.3.1 Error log
Records errors occurring in the controller. The most recent 1,000 errors are recorded. The data is saved in SRAM.
The error log is regularly updated. If you wish to secure particular log data, use error trigger logs or suchlike.
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 conjunc-
tion with the operation log helps in pursuing the cause of errors.
A: Receive button

B: Jump to source code button

C: Error information button
