I am having A problem programing a plc. I have to make a program that does the following, You have to use one push button I:1/0 to control 4 lights O:3/2-O:3/5. And the program should do the following, Push the button and a light comes on push the same button and the light will go out and the next one will come on repeating it self even when it gets to the 4th light, "when the 4th light goes out" the 1st on will come on therfor starting the cycle over. And I can only use (If needed) one shot rising (OSR), latch and unlatch, B3 locations, NO and NC contacts.
If you can help out thats great. thank you Dave
