Since data conditions are judged based on the data sampled at the specified sampling interval, a trigger will not be detected if
the condition is not satisfied at the time of data sampling.
If the value of the target data cannot be represented in the specified data type, an event does not occur when the condition is
satisfied.
For the number of conditions which can be specified for the compound condition, refer to the following:

■Single condition
A single condition compares monitoring data and trigger values (limited to constant values) with the monitoring condition.
An event occurs when the condition changes from not being satisfied to being satisfied.
When the condition also changes from being satisfied to not being satisfied, the event is restored.
