■Data condition
A trigger occurs when the specified data meets the specified condition.
• =: When the current value of monitored data is equal to the comparison value
• : When the current value of monitored data is not equal to the comparison value
• : When the current value of monitored data is greater than or equal to the comparison value
• >: When the current value of monitored data is greater than the comparison value
• : When the current value of monitored data is less than or equal to the comparison value
• <: When the current value of monitored data is less than the comparison value
• : When the monitored data turns FALSE  TRUE
• : When the monitored data turns TRUE  FALSE
• At change: When the current value of the monitored data changes
■Fixed Cycle
A trigger occurs in the specified interval after logging starts.
However, when the specified interval in the fixed cycle and the collection timing are not matched, a trigger occurs at the first
sampling after the specified fixed cycle interval is elapsed.
The cycle can be specified is 1 to 86400000 [ms].
• When the fixed cycle is specified to 10 seconds
Sampling interval
10 sec.
Fixed cycle (10 seconds)
■System start
A trigger occurs at system start (at completion of initialization processing) automatically. When this condition is used, set the
start condition of logging setting to "Starts automatically".
■Trigger command
A trigger occurs when System.LoggingRef[1..10].Cd.Trigger is set to TRUE.
