General sampling delay time area (Un\G800 to 805)
The data sampling monitoring interval actually operating on the high speed data logger module can be checked in this area.
The sampling delay time of data logging, event logging, and report function that are running general sampling can be checked
in this area.

Allowed general sampling delay time
■General sampling delay time (moving average) (Un\G800 to 801)
The general sampling delay time is stored as the moving average over 30 times. (Unit: milliseconds)
■General sampling delay time (maximum) (Un\G802 to 803)
The maximum value of general sampling delay time up to the present is stored. (Unit: milliseconds)
■Allowed general sampling delay time (Un\G804 to 805)
The allowed general sampling delay time is stored.
When 'general sampling delay time (max)' (Un\G802 to 803) exceeds the allowed time, 'general sampling delay' (X1E) turns
ON.
0: Among the data sampling time of data logging, event logging, and report in which the general sampling is specified, the
allowed time is half of the shortest sampling time. (Example: When the sampling time is 0.1 seconds, the allowed time will be
50 milliseconds.)
Other than 0: The specified value is the allowed time. (Unit: milliseconds)
About general sampling delay time
• The high speed data logger module performs general sampling of data logging, event logging, and report
every 100 milliseconds. If the data sampling interval is set to 0.2 seconds or higher, elapsed time is checked
every 100 milliseconds and general sampling is performed as required.
• If there are many general sampling settings or too much data, sampling takes time, and there may be cases
in which sampling each 0.1 seconds or checking the elapsed time cannot be done. In this case, the general
sampling delay time is set as the actual sampling time minus 100 milliseconds
• When a general sampling is delayed, at maximum, there is the possibility that a sampling delay occurred in
the general sampling delay time of data logging, event logging, or report function. (Page 349 Checking
method for the processing time)
• When access target CPU error (power interruption or network failure) is detected, the sampling time will
extend to a maximum of the response monitoring time during detection. (Page 135 [Response
monitoring time] tab)
