Data sent to each slave station is written with the TO instruction. As in the case of the
input data, the data order differs according to whether the parameters were set by a
sequence program or by the configura-tion software.
(a) Parameters set by a sequence program
If the parameters were set by a sequence program, the data is saved as a series of
words of a slave station. In the case of double-word data, the data is saved as the
lower word followed by the upper word. If an odd number of byte input modules is
available, one byte of free area must be inserted in order to arrange the data as a
series of words.
See the example below.
<Example>
Station 1 - Byte output modules = 3
Word output modules = 2
Double-word output modules = 2
Station 2 - Byte output modules = 1
Station 3 - Byte output modules = 1
