• A. A point that exists only in software and is not a hard-wired point
• B. Digital output
• C. Accumulator
• D. Pseudopoint

Answer: (A)

Understanding how points are used in direct digital control, a pseudopoint is a point that exists only in software and is not tied to any physical, hard-wired input or output. The option that defines a pseudopoint this way matches precisely what the term means in practice, so it’s the best choice. Digital output refers to an actual hardware channel that drives devices; an accumulator is a register used to sum values, not a software-only point; the term pseudopoint appears again as the label, but the question asks for the definition, which the chosen statement provides. In real use, pseudopoints let you model and test control logic in software before hardware is wired, making development easier and faster.
