Q 2
**Question 1**

A down-counter output instruction will decrement by 1 each time the counted event occurs.

- ○ True
- ○ False

---

**Question 2**

Counter C5:1 starts counting:

Ladder Logic Program Diagram:

- **Inputs**
  - L1
  - PB1
  - C5:0/DN
  - PB2

- **Logic Elements**
  - B3:0/0 [OSR]
  
- **Counter Setup**
  - CTU (Count-Up Counter)
    - Counter: C5:1
    - Preset: 32000
    - Accumulated: 0

- **Outputs**
  - L2
  - PL
  - C5:0 (RES)
  - C5:1 (RES)

The diagram shows a ladder logic program with components detailing conditions under which a counter starts counting.

**Options:**

- ○ Whenever input PB2 is actuated.
- ○ Whenever input PB1 is actuated.
- ○ When the accumulated value of C5:0 reaches 32,000.
- ○ Whenever input PB1 is actuated or whenever input PB2 is actuated.
