4.1.6 I/O Number of FP0 I/O Link Unit (for right side expansion)
The I/O allocation of FP0 I/O link unit “FP0-IOL” is determined by the installation
location.
Unit First expansion Second expansion Third expansion
Input (32 points) X20 to X3F X40 to X5F X60 to X7F
Output (32 points) Y20 to Y3F Y40 to Y5F Y60 to Y7F
Specifying X and Y numbers
On the FP
Σ
and the FP0, the same numbers are used for input and output.
Example: The same number “X20 and Y20” can be used for input and output
Tip
Expression of numbers for input/output relays
Since input relay “X” and output relay “Y” are handled in units of 16 points,
they are expressed as a combination of decimal and hexadecimal numbers as
shown below.
