7.4 What is I/O Number?
I/O numbers represent addresses that are used in user programs to perform the following:
• Inputting ON/OFF data into the C Controller module
• Outputting ON/OFF data from the C Controller module to the outside
(1) Inputting and outputting ON/OFF data
Input (X) is used to input ON/OFF data to the C Controller module.
Output (Y) is used to output ON/OFF data from the C Controller module.
(2) I/O number notation
I/O numbers are expressed in hexadecimal notation.
When 16-point I/O modules are used, I/O numbers are consecutively assigned to
respective slots, each of which is 0 to F as shown in Figure 7.13.
The following applies to each module.
• For an input module, "X" is prefixed to the I/O number.
• For an output module, "Y" is prefixed to the I/O number.
