Hi everyone
I am a beginner in this field and I have a project to control traffic light 4 way signals for this I have used a master TP timer and use comparison for turning on or off of a specific light and Its working fine and smoothly.
Now I want to take input from HMI to control While the traffic light program is running: Operator enters a time from HMI Operator presses a button. A selected signal (example: Green_A) should: Turn ON immediately Stay ON for the entered time After time finishes: System should automatically return to normal auto traffic logic. Can anyone guide me how to do it. should I have to change my logic or can be fit with it.
