4. A Normally-Open Pushbutton is used in the Micro850 PLC control system to control Lamp 1 and Lamp 2 through the PLC program as shown below. When the Pushbutton is initially not touched, the logic function that the PLC program implements can be described as Pushbutton (N.O.) Lamp 1 Rung 1 HH DIO DO1 Pushbutton (N.O.) Lamp 2 Rung 2 H DIO DO2 (a) Lamp 1 is always ON until Lamp 2 is ON (b) Lamp 2 is always ON until Lamp 1 is ON
