Allocation of Custom Bit Area and Custom Data Area
The Custom bit area (brevity code: x) and Custom data area (brevity code: d)
are the areas for controls and statuses related to axes. With [Bit area type
(m+0)] and [Data area type (m+2)] of [Unit area range setting] in the allocated
DM area words, the area types on the CPU Unit are specified. With [Bit area
first address (m+1)] and [Data area first address (m+3)], the first address of
each area on the CPU Unit is specified.
Up to the words for the biggest axis number set to other than [0:Unused] in the
axis allocation parameter [P1AA01: Physical axis setting] are allocated.

Custom I/O Area Allocation
Custom I/O Area (brevity code a_A-H) is the area to exchange custom data
between the CPU Unit and MC Unit. In the Custom I/O Area, there are eight
general I/O areas A-H, and the size 1-160 words can be specified for each
area.
In case of general I/O A, the number of transferred words is specified with
[PORT_A No. of transferred words (bit 00-07 of m+4)] of [General I/O area
range setting] in the allocated DM area. The area type on the CPU Unit is
specified with [PORT_A Area type (bit 08-14 of m+4)]. In addition, transfer
direction is specified with [PORT_A Direction]. The first address on the CPU
Unit is specified with [PORT_A First address (m+5)].

Purpose
The greatest axis number that is going to be used
determines the number of allocated.
