(28) Master Function Receive Data (addresses 0700
2047)
The data that was received from each slave node is stored. The data assignment
is shown below. The data is stored in the word boundaries of the slave nodes.
Double-word data is stored in the order of lower word first and higher word next.
If there is an odd number of byte input modules, one byte of empty area will be
inserted for alignment at the word boundary. Bit input modules are treated in the
same way as the byte input modules.
The following shows an example:
<Example>
1st node - Number of byte input modules = 3
Number of word input modules = 3
Number of double-word input modules = 2
2nd node - Number of byte input modules = 1
3rd node - Number of byte input modules = 1
