Number of I/O points and I/O number
The first I/O number and the range of I/O numbers are determined as follows ----
• First I/O number: The first two digits are determined by the set station number.
• Range: The range of I/O numbers is automatically determined, according to the settings of the
number of I/O slots on the mount base, the number of I/O points occupied by each slot on the
mount base, and the partition status.
I/O numbers are set for all slots even if there are free slots. Therefore, the I/O numbers remain
unchanged even when modules are added later or slots become free.
One or two I/O numbers are assigned to each input or output point depending on the partition
status setting, as described below.
• FREE: Both an input I/O number (Xxxx) and output I/O number (Yxxx) are assigned. The
I/O number (Xxxx or Yxxx) corresponding to the I/O module mounted can be selected. (See
Example 1.)
• FIX: Since I/O slots are classified into two types for input modules and output modules, only
one I/O number corresponding to the type (input or output) of the I/O slot is assigned (Xxxx
for input or Yxxx for output). (See Example 2.)
Example 1: I/O numbers assigned and number of points occupied when the first I/O number is
000 and the partition status is set to FREE

Each slot is assigned an input I/O number (Xxxx) and output I/O number (Yxxx). In this
table, X and Y are omitted and only numbers are indicated. The value 000, for example,
indicates that both X000 and Y000 are assigned.
