6.3.5 Setting station numbers
As the station number of an I/O unit, set the first two digits of the numeric part of its I/O
number with the station number switch on the front of the remote I/O station module. When
setting station numbers, note the following points:
• Do not use duplicate numbers. If I/O modules are mounted in the CPU unit and “PI/O
mounted” is set, then the value 00 is assigned as the first station number. Take care so that
any other station numbers do not duplicate this number.
• Station numbers need not be assigned in the order in which cables are connected.
• If I/O units are connected to the RI/O-1 port on the CPU unit, their station numbers must be
within the range of 00 to 3E. If they are connected to the RI/O-2 port, the station number
range must be from 40 to 7E.

(*1) I/O number is assingned 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.
