Step 1
Set the area, start word, and words allocated for each block with the use of the CX-Integrator.
Step 2
Allocate words to all node addresses in each block as shown below with the use of the CX-Integra-
tor.
• Each address is allocated at least one byte (rightmost or leftmost byte).
Note a) You can set the order of all blocks as you desire.
b) Node addresses do not have to correspond between an output block and input block.
c) The same node address cannot be allocated more than once.
