NOTE
1 If data number n is within the valid range, but it is beyond the
number of data items actually stored, no data is output, and
read operation terminates with the number of data items l
set to 0.
Example: When the data number n is within the number of
actually stored data items, and (n + 1 – 1) exceeds
the number of actually stored data items, just the
stored data is output, and read operation
terminates normally. In this case, the number of
data items l is changed to the number of the
output data items.
2 Suppose that the number of target axes is 2, and the sample
data save function is enabled (bit 2 of parameter No. 6350
is set to 1). Data numbers ranging from 0 to 131071 are then
valid. When 131000 data items are actually stored (data
numbers 0 to 130999), and an attempt is made to read data
starting from the data item having data number n = 131020
((1) in the figure below), no data is output, and the number
of data items l is set to 0.
Example: Suppose that under the same conditions as
explained in the above example, an attempt is
made to read 120 data items (l) starting from a
data item having the data number 130900 (n) ((2)
in the figure below). Then, data items with data
numbers 130900 to 130999 are output, and the
number of data items l is set to 100. Also, when
n is 130990 and l is 120 under the same
conditions ((3) in the figure below), data items with
data numbers 130990 to 130999 are output, and
l is set to 10.
