Section 6-2
6-2-4
AR Area
AR bits are used for specific functions related to the operation of the Custom-
izable Counter Unit’s special I/O. For details on the functions of individual bits,
refer to
6-4 AR Area.
6-2-5
LR Area
This area can be used for data exchange with user-set words (in the CIO, WR,
AR, HR, DM, or EM Area) in the CPU Unit.
The words used in the CPU Unit are set in the Unit Setup Area (DM 6601 to
DM 6604) as shown below. The input and output areas in the LR Area are
allocated in the order input area
®
output area starting from the first word of
the LR Area. The number of words in the areas are determined by the refresh
settings.
General-purpose I/O is exchanged between the LR Area and the user-set
words in the CPU Unit, as shown in the following table.
Note
When LR Area bits are not being used for the above functions, they can be
used as work bits.
