Words are allocated to slaves starting from address 0 in the output (OUT) and

IN blocks. Each address is allocated at least one byte (rightmost).

• More than one word is allocated for each slave (according to its node address) with more than16 I/O points.

• The rightmost byte of the word is allocated to each slave that has less

	than 16 I/O points.
User-set Allocations
	The following methods are used for user-set allocations:
	• Using a Master User Allocations Table (allocated DM Area words)
	• Using the Configurator
Using the Master User	In the Master User Allocations Table, set the areas and first words for the out-
Allocations Table	put block (OUT 1) and the input block (IN 1) and set the area and first word for
	the Allocation Size Setup Table. In the Allocation Size Setup Table, set the
	allocation sizes for the slave input and output blocks. Each slave can be allo-
	cated two blocks, OUT 1 and IN 1, according to the settings in these tables.
