Data changes between data sampling processes

Data changes occurred between the data sampling processes are not sampled because a high speed data logger module
only samples data from a CPU module at the specified data sampling intervals.
Adjust the data sampling interval according to data to be sampled.

Detecting data condition establishment

The determination of the data condition is executed with the data sampled at the specified data sampling interval.
When the data condition is specified for the trigger, event, or file switching, the determination of the data condition is not
detected if the condition is not established at the data sampling.
Set a longer time for the condition establishment time than the data sampling interval.

The value of the actual data is changed

The data is not sampled by the high speed data
logger module.
The condition holds true at two points.
The condition state is detected as 'true', only
when the bit data is turned ON at the time of data
