Using Settings in Words Allocated in DM Area: 16,000 points (IN: 500 words

Words are allocated to each node in the above data areas in any order.
The following limitations apply:
• Using Settings in Words Allocated to DeviceNet (Master) Unit in DM
Area
The following limitations apply when allocating words using settings in the
DM Area.
• Words are allocated in 2 blocks (OUT 1, IN 1). Each block consists of
sequential words.
• Words for each slave are allocated inside the allocated words in order of
node number. (It is not necessary to allocate words to unused node num-
bers.)
• The leftmost byte of a word cannot be allocated to an 8-point Slave.
• Using the Configurator
Using the Configurator allows much wider allocation than using settings in
the DM Area.
• Words are allocated in 4 blocks (OUT 1, OUT 2, IN 1, IN 2). Each block
consists of sequential words.
• Words for each slave can be allocated inside the allocated words in any
order.
• Limitations That Apply to Both Methods
The following limitations apply when allocating words using either settings
in the DM Area or using the Configurator.
• The maximum that can be allocated in one block is 500 words.
For Slaves with more than 8 points, the first byte cannot be specified as
the leftmost byte (7 to 15).
• The same Slave cannot be used for more than one DeviceNet (Master)
Unit.
Words are allocated to Slaves as follows:
• 8-point Slaves: Allocated leftmost or rightmost byte of a word.
• 16-point Slaves: Allocated 1 word.
• Slaves with more than 16 points: Allocated multiple words (for Slaves
with an odd number of bytes, the last byte will be the rightmost byte).
63
Calculate from the number of words allocated in the data areas and the
number of words allocated to the Inverters (4 to 8 words).
The DM Area cannot be manipulated by bit, so it cannot be allocated for
remote I/O for Inverters.
