1.2.3 I/O combined module
(1) I/O numbers of I/O combined modules
There are two types of I/O combined modules:
• Module using same I/O numbers for input and output
Since same number is used for input and output, the I/O numbers to be
used can be saved.
• Module using sequential I/O numbers for input and output
Since I/O assignments are the same for A series, it is useful when replacing
modules from those of A series.
Module using same I/O numbers for input
and output (QH42P)
Module using sequential I/O numbers for input
and output (QX41Y41P)
(2) Configuration of when an I/O combined module is used
For the QH42P, QX41Y41P, and QX48Y57, use them in the configuration below.
