How is the binary status for each I/O group displayed?

• A. The binary status is shown as a decimal value without a label.
• B. The binary status is shown in hexadecimal form.
• C. The binary status is shown as a decimal equivalent shown as '__:DEC' at the top of the group's page.
• D. The binary status is shown as binary digits only.

Answer: (C)

The status readout for an I/O group is presented as the decimal equivalent of the binary pattern, shown at the top of the group's page with a DEC label. This labeling makes it clear that you’re looking at the decimal interpretation of the on/off states across the group, so you can quickly read and compare values without doing manual binary-to-decimal conversions. Plain decimal without a label can be ambiguous, hexadecimal isn’t the format used here, and showing only binary digits would require extra conversion steps. The DEC tag keeps the display unambiguous and easy to scan across groups.
