Design the electrical ladder diagram and PLC ladder diagram for the PLC problem below. 1. Lamp 1 turns on when momentary push-button switch 1 (PB1) or momentary push-button switch 2 (PB2) is pressed. 2. Lamp 2 turns on when momentary push-button switch 2 (PB2) and momentary push-button switch 3 (PB3) are pressed. 3. When the momentary push-button stop switch is pressed, Lamp 1 and Lamp 2 turn off. Lamp 3 is on when both Lamp 1 and Lamp 2 are off.

Question 7: Look at this PLC off-delay circuit and explain and describe how it will function, in detail, referencing to each component in the circuit shown and how each component will work together to give an off-delay.
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 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
ASYNCIN Dan Synchronous System CLOCK Figure Q4 (b) The circuit in Figure Q4 (c) consists of edge triggered flipflops. The second flipflop receives the clock signal through a long slow path which results in delay.

Which of the following statements is true for an SCR. O A. It is an on-only controllable switch, which is turned on by a gating signal and cannot be turned off externally; only system conditions can turn off the device once it is on O B. None of the other choices are correct O C. It is a controllable switch, which is turned on by applying a gating signal and is turned off when the gating is removed O D. It is an off-only controllable switch, which is turned off by a gating signal as needed O E. It is an on-off controllable switch, which is turned on and off by a gating signal as needed
Write a PLC program that will operate a light (Q0.0) according to the following sequence: A momentary contact normally open PB (I0.0) is pressed to start the sequence. The light is switched on and remains on for 5 seconds. The light is then switched off and remains off for 5 seconds. A counter is incremented by 1 after this sequence. The sequence then repeats for a total of five counts. After the fifth count, the sequence will stop and the counter will be reset to zero. Any help would do. No explanations required
