PLC Assignments
Assignment 1:-
Develop a ladder logic for a FLASHER (10 second duration) such that, when Switch is turned ON,
The FLASHER should glow for 10 second duration.
The FLASHER should not glow for 10 second duration.
The FLASHER then continues.
Assignment 2:-
Develop a ladder logic for a FLASHER (10 second duration) such that, when Switch is turned ON,
The FLASHER should not glow for 10 second duration.
The FLASHER should glow for 10 second duration.
The FLASHER then continues.
Assignment 3:-
Develop a ladder logic for FLASHER such that, when Switch is turned ON,
The FLASHER should glows for 15 second duration.
The FLASHER should not glow for 10 second duration.
The FLASHER then continues.
Assignment 4:-
Develop a ladder logic for FLASHER such that,
The FLASHER should not glow for 5 second duration.
The FLASHER should glows for 15 second duration.
The FLASHER runs for 30 second and then stops.
Assignment 5:-
Develop a ladder logic for FLASHER such that,
The FLASHER should glows for 10 second duration.
The FLASHER should not glow for 5 second duration.
The FLASHER runs for 1 minute and then stops.
Assignment 6:-
Develop a ladder logic for FLASHER such that,
The FLASHER should glows for 5 second duration.
The FLASHER should not glow for 10 second duration.
The FLASHER runs for 10 second.
Then FLASHER stops for 15 second.
Then FLASHER runs for 2 minutes then stops.
Assignments 7:-
Three pumps are to be monitored. If all 3 pumps are running, one digital output should glow steadily, if any two pumps are running the output should flash slowly and if only one pump is running then the output flashes at a faster rate. (Only one digital output).
Assignments 8:-
Program an alarm system such that the following logic is operated for the four inputs:
1) If only one of any inputs is on, one yellow lamp turns on for 20 seconds.
2) If 2 inputs are turned on, a red light turns on after 5 seconds.
3) If 3 inputs are turned on, an alarm is fired.
4) If all 4 inputs are turned on, the alarm is fires and the Fir station is called.
5) With one push button the system is reset.
