• Number of points specified in n2 is read from the device specified in (D1) to the offset specified in (S1)+2 of the refresh
device assigned for the device specified in (S1)+1 of the target station specified in n1 and (S1)+0.
• At the above configuration, number of points specified in n2 is read starting from the offset (W1063) specified in (S1)+2 of
the device assigned for the station number 4, then the number of points is read to devices starting from the device specified
in (D1).
When a refresh range per station is assigned in transfer settings, specify number of read points so that the
range read data from the specified offset is within the range assigned in the same transfer setting. An error
occurs if the number of read points over the range assigned in each transfer setting is specified.
