NOTE
1 The DI and DO addresses for the basic and extension units
run contiguously. These basic and extension unit DI and
DO addresses are allocated to the I/O Link as a group. For
example, when the DI and DO top addresses are X0004
and Y0000 (m = 4 and n = 0), respectively, then the
addresses are allocated as shown in the following table.
2 When the 2A output module is used, the addresses for the
DIs of the module cannot be used. (When the 2A output
module is used as extended unit 3, X13 to X15 cannot be
used.)
3 In the analog input module, the DO space is used as an
input channel selection area.
