3.6.10 Information linkage function area
(a) The setting status of [Time synchronization setting] is stored.
For [Time synchronization setting], refer to the following.
Section 7.6.2 Setting items in Time synchronization setting
0: [Synchronize with PLC CPU time]
1: [Synchronize with SNTP]
(b) When selecting [Synchronize with SNTP] in [Time synchronization setting]
This area is set when the time information was obtained from the SNTP server
computer.
If the time information could not be obtained from the SNTP server computer, this
area is not set since the operation for when [Synchronize with PLC CPU time] is
selected is performed (Time is synchronized with the programmable controller
CPU).
When [Synchronize with SNTP] is selected in [Time synchronization setting], the time
information obtained from the SNTP server is stored.
(When [Daylight saving setting] is enabled, time corrected to daylight saving time is
stored during the period of summer time.)

The cumulative number of times that a monitoring interval timeout has occurred is
stored.
The monitoring interval timeout occurs when trigger detection has not been completed
within the monitoring interval.
If this timeout occurs, perform the following:
• Increase the monitoring interval
Increase the sampling interval of the tag that is used for trigger conditions.
• Reduce the trigger detection time.
Reduce the number of configured jobs.
