traffic light simulator logixpro with crosswalk

The entire post is by no means everything that is needed, just some ideas.Light show program that will enable with correct password. acc that will activate the GREEN light in its direction and a RED light in the other direction.Īfter that situation is over, RES the timer and restart it. You are working with at least 3 different traffic situations.įor situation 2 or 3 maybe stop the RTO and MOV a value into the timer. Use the B bits to drive additional logic that will operate the 'Physical' (O output bits). To overcome this simulator obstacle, I believe that you are going to need to derive several different traffic situations and use them to output to 'Soft' outputs (use B output bits). That in itself 'may' prevent you from simulating the project properly. In order for cars to move, the RED light must be off. Some of the problem is that the simulator only stops the traffic in either direction when the (Physically Simulated O output) RED light is on. They allow you to make a rung true or false based on a value comparison and will be very useful. I can't remember the exact instruction names, but I remember GEQ is Greater than or Equal and the rest are on the ribbon by it. If your East-West lights a green, then your North-South lights are Red. Another advantage of this approach is that you can turn on multiple outputs in a certain state. You can also use the current states of your light to change a crosswalk light based on conditions, such as the button has been pressed. The number in N7:1 can be changed or kept based on your sensors values and your timers for how long the light should be on and off. Now, you can use logic to set what the number in N7:1 will be based on things that happen. Yellow only works when the number in N7:1 is 2. Now, green only turns on when that value of N7:1 is the number 1. Then give each light color a number, such as: Select an address (such as N7:1) and use this address as a sequence value.

What I suggest is trying to rewrite the program in a new file, but do this:

AKA does not respond to any outside events. This is fine if you want a light that cycles and does nothing else. In order for any of the lights to turn on, you have to be in its assigned range. You have a timer that is timing up to 26 seconds. I don't have a lot of time at the moment, but think about this for a minute.
