Allocated Words
A total of 100 words are allocated from words in the CPU Unit’s DM Area for
Special I/O Units (D20000 to D29599) according to the unit number (0 to 95)
set for the Customizable Counter Unit using the rotary switches on the front of
the Unit.
• The following table shows the relationship between the unit number setting
and the CPU Unit’s allocations.
The allocated words are divided into two areas: The Initial Setting Area (m to
m+9), to which specific functions have been allocated, and general-purpose
words (m+10 to m+99), to which functions have not been allocated.

1.
The contents of the Initial Setting Area (m to m+9) are transferred from the
CPU Unit to the Customizable Counter Unit at startup or when the Custom-
izable Counter Unit is restarted.
2.
General-purpose words (m+10 to m+99) can be allocated to user-set
words in the DM, EM, IR, LR, or AR Area in the Customizable Counter Unit.
The contents of general-purpose words are exchanged with the CPU Unit
at the CPU Unit’s I/O refresh (i.e., on the CPU Unit’s timing).
