For Monitor sampling
Select between Single sampling or Continuous sampling.
Single:
•
Sampling from start to end is performed only once.
• Continuous:
Sampling from start to end is performed continuously. When sampling ends, the data is
added to History, and starts the next sampling. (Refer to page 134)
Select between High Speed sampling or Monitor sampling.
High speed sampling is available only the FR-E700 series is connected with USB (not
available when connected through GOT). Since some monitor items are different between
the sampling mode, the setting of uncommon sampling item is cleared when changing the
sampling mode
Set interval (cycle) of data sampling.
Sampling interval is fixed depending on a number of sampling items and communication
setting. (Refer to page 129)
Set interval (cycle) of data sampling.
For High Speed sampling, set Mask count (available from 1 to 40) to fix the sampling
interval. Refer to the following formula for sampling interval.
Sampling interval is approximately equal to (Mask Count + 1)
Example: when the Mask Count is 1
Sampling interval is approximately equal to (1 + 1)
Set maximum sampling time. When elapsed time exceeds the sampling time, sampling
stops. Maximum sampling time can be set as follows. (Refer to page 129)
High Speed sampling: Maximum sampling interval
Monitor sampling: Maximum sampling interval
Example: when the Mask Count is 1 for High Speed sampling
Maximum sampling time = 8000ms
