Numbers and Assignment in System
This section describes input/output numbers and module numbers.
Module input/output number
The input/output numbers are octal numbers. Input is assigned to "X" and output to "Y".
Input/output numbers are used for communications of ON/OFF data between I/O modules and the CPU module.
Octal for input/output numbers (X/Y)
Input/output numbers (X/Y) are automatically assigned as shown below.
X0 to X7, X10 to X17, X20 to X27, ..., X70 to X77, X100 to X107, ...
Y0 to Y7, Y10 to Y17, Y20 to Y27, ..., Y70 to Y77, Y100 to Y107, ...
However, X16, X17, and Y12 to Y17 of the FX5UJ-24M and X44 to X47 of the FX5UJ-60M are vacant numbers.
Numbers for added I/O module
To an added I/O module, input numbers and output numbers following the input numbers and output numbers given to the
preceding device are assigned. The last digit of the assigned numbers must begin with 0.
Module number of extension modules
The CPU module automatically assigns numbers (1 to 16) to intelligent function modules, safety main module or bus
conversion module as module numbers in order of distance from the CPU module.
• Intelligent function modules, safety main module or bus conversion module connected to the CPU module
Module numbers are assigned to intelligent function modules in order of distance from the CPU module: No.1, No.2, ...,
No.16.
• Products to which module numbers are not assigned
