PLC Programming: Boolean Logic Fundamentals Quiz…

Q: Which Boolean logic gate performs the logical AND operation?

AND — The AND gate outputs true only if all inputs are true.

Q: What is the output of an AND gate if input A is TRUE and input B is FALSE?

FALSE — An AND gate requires all inputs to be TRUE to produce a TRUE output.

Q: Which gate represents the OR logic function?

OR — The OR gate outputs true if at least one input is true.

Q: What is the output of an OR gate if input A is TRUE and input B is FALSE?

TRUE — An OR gate produces a TRUE output if any input is TRUE.

Q: Which gate inverts the input signal?

NOT — The NOT gate inverts the input, changing TRUE to FALSE and vice versa.

Q: If the input to a NOT gate is FALSE, what is the output?

TRUE — The NOT gate inverts the input, so FALSE becomes TRUE.

Q: Which of the following Boolean expressions represents the AND operation?

A * B — Multiplication (*) is often used to represent the AND function.

Q: Which of the following Boolean expressions represents the OR operation?

A + B — The plus sign (+) typically represents the OR function.

Q: Which gate is equivalent to an AND gate followed by a NOT gate?

NAND — NAND is 'NOT AND', inverting the output of an AND gate.

Q: What is the simplest way to represent a TRUE state in PLC programming?

1 — TRUE is typically represented by the binary value 1.
