3) Create CSV File... button
Click this button to output the module error history in a CSV file.
POINT
(1) If errors have frequently occurred in the C24, "*HST.LOSS*" may be displayed
instead of error codes in the Error Code column.
(Example)
If too many "*HST.LOSS*" are displayed, increase the number of errors to be
collected per scan in the "PLC RAS" tab of the "PLC Parameter" dialog box.
For setting, refer to the user's manual (Function Explanation, Program
Example) for the CPU module used.
(2) When the same errors consecutively occurred, only the error code for the first
occurred is displayed on the "Error History" screen.
