I/O Numbers of Modules
An I/O number is a number (hexadecimal) assigned to I/O modules and intelligent function modules to communicate data with
the CPU module or remote head module. On/off data are classified into two types: input and output, and the symbol, "X" for
input, and "Y" for output, is added in front of the I/O number.
I/O numbers are automatically assigned in sequential order. On the main base unit, the I/O number starts from 00H, which is
given to the module on the right side of the CPU module or remote head module.
On the extension base unit (1st level), the I/O number starts from the next number of the last I/O number on the main base
unit.
Each slot on the base unit occupies I/O numbers corresponding to the number of points of the module mounted.
CPU
Upon placing a module on the "Module Configuration" window, the I/O numbers are automatically assigned according to the
number of occupied points of the module.
Even though the mounting position of the module is changed, the I/O numbers once assigned remain unchanged.
