■Description, data type of result
Setting data Description
(D) Transfer destination device starting No.
(S) Transfer source device starting No.
(n) Number of words to be transferred (1 to 1000000000)
Processing details
• The contents for n words from device specified with (S) are batch-transferred to the n words from device specified with (D).
• Data can be transferred if the devices of the transfer source and destination overlap. Data are transferred from devices,
starting with the one at (S), for transfer of data from devices of larger numbers to those of smaller numbers, or starting with
the one at (S)+(n-1) for transfer of data from devices of smaller numbers to those of larger numbers.
• Adjust an executive task, the number of transfer word referring to the operation processing time so that this instruction may
not obstruct the execution of the Motion operation because processing time becomes long in argument to the number of
words (n) to be written.
• The combinations for transfer destination device and transfer source device that are set to (D) and (S) are shown below.
