Example
Set the FIFO acquisition interval to 1 s.
FR1,1S
Description •
Set the acquisition interval to a value greater
than the scan interval.
•
If you set the scan interval to a value greater
than the acquisition interval using the XV
command or from the screen, the acquisition
interval is automatically set equal to the scan
interval.
•
The DX has a circular FIFO (First In First
Out) buf
fer
. The DX acquires measured/
computed values to the internal memory at
predetermined time intervals from the time
the power is turned on. The DX outputs the
data when you send an FF command. The
DX remembers the previous output position
for each connection and updates the position
when the DX outputs the next set of data
when you send another FF command. This
scheme compensates for the differences in
the processing power of the measurement
PCs and the communication delay. It enables
data to be retrieved without any dropouts if the
measurement PC reads the data before the
ring buffer is overwritten. For details on the
FIFO data output process, see appendix 5.
