● Error code
An error code is stored in the area corresponding to the event logging setting where the event logging error is occurring.
When errors related to access target CPU occur, the error code of the access target CPU may be stored to other settings
which also use the same access target CPU.
● Number of latest folders
The number of latest folders is stored.
● Number of latest files
The number of latest files is stored.
● High speed sampling failure count
When high speed sampling is selected in the sampling setting and when the data sampling speed cannot catch up with the
timing of the sequence scan or specified time interval, the total number of times for which the data is lacking is stored.
When high speed sampling fails, the following cases occur.
• An event condition establishment may not be detected
• When the data condition is selected in the period setting, the satisfaction of data conditions may not be detected
• Data to be displayed with GX LogViewer is lacking
Take corrective actions by referring to the following:
