4.5 Definition of I/O Number
I/O numbers indicate the addresses used in a sequence program to input or output ON/
OFF data between the CPU module and other modules.
(1) Input and output of ON/OFF data
Input (X) is used to input ON/OFF data to the CPU module, and output (Y) is used to
output ON/OFF data from the CPU module.
(2) I/O number expressions
I/O numbers are expressed as hexadecimal.
When using 16-point I/O modules, I/O numbers are consecutively assigned to the
slots having
0 to F, 16 points, as shown in Figure 4.16.
The module mounted in the base unit assigns the following:
• For the input module, "X" is assigned at the beginning of the I/O number.
• For the output module, "Y" is assigned at the beginning of the I/O number.
