Numbers and Assignment in System

Input/output numbers and module numbers in an FX5UC system are explained.

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 communication of ON/OFF data between I/O modules and the CPU module.
• Input/output numbers (X/Y) are octal.
Input/output numbers (X/Y) are automatically assigned as shown below.
X000 to X007, X010 to X017, X020 to X027, ... X070 to X077, X100 to X107, ...
Y000 to Y007, Y010 to Y017, Y020 to Y027, ... Y070 to Y077, Y100 to Y107, ...
• 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 or bus conversion module as
module numbers in order of distance from the CPU module.
• Intelligent function modules 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 to No. 16.
• Products to which module numbers are not assigned
Module numbers are not assigned to the following extension devices.
• I/O module
• Expansion adapter
• Connector conversion module
