Traffic Light System Construct a PLC program for a traffic light system with the following condition: The green light will be ON for 10 second, followed by the yellow light for 3 second and red light for 20. The system will run continuously until the START/STOP switch is deactivated. Figure 12: The traffic light system Two Directional Control of Traffic Light Extend the PLC program for the traffic light system with the following condition:. Red = north/south Green = north/south Amber = north/south Green = east/west Amber = east/west Red = east/west -25 s ·5 s 25 s 5 s

I want you to draw a ladder logic diagram of a garage door to control it by PLC. In my case we have different inputs and outputs and all of them gotta be used in the diagram. I can perfectly interpret the diagram so no need to explain it, I will just require you to draw it. INPUTS : open push button ( OPB ) - close push button ( CPB ) - open limit switch ( OLS ) - close limit switch ( CLS ) - obstacle detection sensor ( ODS ) - safety sensor ( SS ) - emergency stop push button ( ESPB ) - reset button ( RB ) OUTPUTS : motor starts ( MS ) - motor stops ( MSTP ) - motor forward ( MF ) - motor reverse ( MR ) - Error display ( ER ) OPERATİNG MODES : automatic mode ( AM ) - manual mode ( MM ) NECESSARY TIMERS : T1 ( delay door movement after obstacle detection ) - T2 ( delay door movement after reversing ) Here is my excercise for today. Please I am requiring a good logic diagram taking into consideration all what was mentioned before. so to sum up, I want you to write a logic ladder diagram…

An emergency stop system is to be designed for a certain automatic production machine. A single “start” button is used to turn on the power to the machine at the beginning of the day. In addition, there are two “stop” buttons located at two locations on the machine, either of which can be pressed to immediately turn off power to the machine. Let X1 = start button (normally open), X2 = stop button 1 (normally closed), X3 = stop button 2 (normally closed), and Y = power-to-machine. (a) Construct the truth table for this system. (b) Write the Boolean logic expression for the system. (c) Construct the ladder logic diagram for the system
1. A mixing vat has an inlet valve, an outlet valve, a mixing motor, and a single level detecting switch (Figure 1). Both valves are opened by solenoids. The level switch closes when the vat is full and stays closed until the vat is empty. Draw a PLC ladder logic diagram and provide the allocation list to do the following: a. When the start button is pushed, the inlet valve opens until the vat is full. b. The mixer motor comes on for 5 min. c. The outlet valve opens until the vat is empty.
