Ladder Logic in LogixPro - Fourway Traffic Light Controller
The light changes as per the sequence listed below:
A. Before switch ON, all 4 roads should get ‘flashing yellow’ soas to enable them to look around and cross the road junction.
B. When switched ON, Main roads 1 & 3 should get greensignals G1/G3 to go straight. This signal remains on for 30seconds.
C. The above signals should be changed over to go right GR1/GR3for 15 seconds only if any sensor S1/S3 of vehicles waiting to turnright is detected in the right turn lane . This will take placeafter a brief yellow signals Y1/Y3 in between.
D. In case no vehicle is waiting for right turn, the roads 1& 3 should be closed with red signals R1/R3 and interim yellowsignals Y1/Y3 for 2 seconds.
E. The above procedure steps B-D should be repeated for sideroads 2 & 4.
F. The signalling continues from steps B-E till switchedoff.
G. The timings for straight or right turns should all beprogrammable. For all changes from Green to Red, interim Yellowsignals should be used.
