Assignment of Input/Output Numbers and Unit Numbers

7.1

Assignment of Input/Output Numbers (X/Y)

If input/output powered extension units/blocks have been connected when the power is turned on, the main
unit automatically assigns the input/output numbers (X/Y) (octal) to the units/blocks.
Therefore, it is unnecessary to specify the input/output numbers with parameters.
Accordingly, it is not necessary to specify input/output numbers using parameters.
It is necessary to assign input and output numbers in the following special function blocks.
• FX -64CL-M

Concept of assigning

When the power is turned on, input/output numbers (X/Y) are assigned in accordance with the following rules.
In the FX -64CL-M, input/output numbers are assigned to connected remote input/output stations.

For details on assignment, refer to the FX
1. Input/output numbers (X/Y) are octal.
Octal numbers are assigned as input/output numbers (X/Y) 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...
2. Unused numbers
Note that unused numbers (which cause the difference between the number of occupied points and the
number of effective points) are generated when the following products are used.
- Main units (FX
- input/output extension blocks (FX
3. Numbers for added input/output unit/block
To an added input/output powered extension unit/block, 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.
When the input/output powered extension unit is connected to the main unit, input/output numbers are
assigned as follows.
