Which tag component identifies the exact terminal on an input or output module?

• A. Location
• B. Bit
• C. Module Type
• D. Member

Answer: (B)

This question is about how you pinpoint a single I/O point within a module. The Bit component is what selects the exact terminal on an input or output module. It goes beyond just identifying the module as a whole (Location) or describing what kind of hardware it is (Module Type). The Bit component specifically designates one discrete channel, so you can address, read, or write to that one terminal. Location would refer to where the module sits or its broader address, not the individual terminal. Module Type tells you what kind of module you’re using, not which terminal within it. Member would apply to parts of a structured variable, not to hardware I/O channels. For a 16-channel module, the terminal you’re working with is the specific Bit that corresponds to that channel.
