Data to be sent to each slave node are set in this area.
Data are aligned on word boundaries of slave nodes and stored as shown below.
For double-word data, the low word is stored first and then the high word.
When the number of byte input modules is an odd number, one byte of an empty
area is inserted.
The following is an example.
<Example>
1st node - Number of byte output modules = 3
Number of word output modules = 2
Number of double-word output modules = 2
2nd node - Number of byte output modules = 1
3rd node - Number of byte output modules = 1
