8.3 Refresh Device Write/Read Instructions
• Number of points specified in n2 is written from the device specified in (S2) 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 written from the device specified in (S2) to the offset (W1063)
specified in (S1)+2 of the device assigned for the station number 4.
When a refresh range per station is assigned in transfer settings, specify number of write points so that the
range written data from the specified offset is within the range assigned in the same transfer setting. An error
occurs if the number of write points over the range assigned in each transfer setting is specified.
