The relationship between the Alarm Log function settings and the sampled data is as follows.

2. Channel No.: Composed of (Block No.)-(Channel No.). The device addresses to monitor and the
conditions for alarm occurrence and recovery are configured in the channels. When the
sampled data is output as a CSV file, the displayed label is “Ch.No.”.
3. Level: It is the level of alarm.

Device tab on the Alarm Log Settings dialog box is selected.
4. Message: The message displayed when an alarm has occurred.
5. Alarm state and time: The alarm state (occurred, recovered, confirmed) and the time the alarm occurred, was
recovered from, and confirmed. When the sampled data is output as a CSV file, the
displayed label varies based on the output method.
6. Label: When the sampled data is output as a CSV file, this is the text displayed in the label row.
