I/O Allocation
Four input words and two output words are allocated to the CP1W-MAD42,
starting from the next word following the last word allocated to the CPU Unit or
previous Expansion Unit or Expansion I/O Unit.
Four input words and four output words are allocated to the CP1W-MAD44,
starting from the next word following the last word allocated to the CPU Unit or
previous Expansion Unit or Expansion I/O Unit.

Writing Set Data
CP1W-MAD42
Write the set data to words (n+1 to n+2). A/D or D/A conversion begins when
the set data is transferred from the CPU Unit to the Analog I/O Unit. Setting
contents are shown as the following table.
Word (n+1) 15 14 13 12 11 10
Value 1 0 0
Word (n+2) 15 14 13 12 11 10
Value 1 0 0
CP1W-MAD44
Write the set data to words (n+1 to n+4). A/D or D/A conversion begins when
the set data is transferred from the CPU Unit to the Analog I/O Unit. Setting
contents are shown as the following table.
Word (n+1) 15 14 13 12 11 10
Value 1 0 0
Word (n+2) 15 14 13 12 11 10
Value 1 0 0
Word (n+3) 15 14 13 12 11 10
Value 1 0 0
Word (n+4) 15 14 13 12 11 10
Value 1 0 0
Even if analog inputs are not used, bit 15 in word (n+1) and (n+2) must be set
to 1.
