4-2-6 Data Allocations for Word Slave Units
Memory is allocated to Word Slave Units in units of 16 bits (1 word).
Slave Units requiring fewer than 16 bits are sill allocated one word per node (the allocation for the set
node address). (See note.)
Note: Even 8-point Slave Units are allocated 1 word. The bits are allocated in the lower byte and the upper byte is
not used.
Slave Units requiring more than 16 bits and 32 bits or less are allocated two words per node (the alloca-
tion for the set node address and the next node address).
In the same way, multiple words are allocated to other Slave Units according to the I/O capacity of the
Slave Unit (including the word for the allocated node address and following words).
