Function
(1) Writes device data for the number of points specified at n2 of the device
offset, which is specified for n1, of the device data storage file in the standard ROM.
n1 is the offset from the head of device data storage file and specified by word offset (in units
of 16-bit words).
(2) Since the device data write position completion device (
automatically turns ON at execution of the END instruction, which detects the completion of
this instruction, and turns OFF with the END instruction of next scan, it is used as an
execution completion flag of this instruction.
