In Ladder Logic a program is represented by a graphical diagram based on circuit diagrams of relay-based logic hardware. It is mostly used in the development of software for PLCs. The most important advantage of this programming language is that engineers and technicians would be able to grasp it easily because of its resemblance to hardware systems. I am an engineer and I personally have found it very easy to understand. I am sure that Ladder Logic is going to be immensely popular among the engineering community in the years to come. ....etc

The project is designed to automatically operate an electric bell several times as required in an educational institution like school or college. It overcomes the difficulties of switching the bell on/off manually. This proposed system has an inbuilt real time clock (RTC) to keep a track of the time and thus to switch on/off the load accordingly.

The project uses a real time clock (RTC DS1307) interfaced with the microcontroller of the 8051 family. While the set time equals to the real time, the microcontroller gives command to the correspon ....etc

plc elevator ladder logic example pdf

On modern elevators the control logic is PLC based, probably because relays are more expensive than electronic components. Besides a PLC makes simple the electrical connections and reduces the chance of failure. On old elevators the direction of the car is controlled by selectors mounted in the shaft, one at each floor. On modern elevators there may be one impulse switch only, mounted on the top of the car. When the elevator moves the impulse switch detects a sequence of magnets placed in the shaft, then s ....etc

I need a ladder diagram of an intelligent traffic control at a 4 way junction.I am pasting the code.here using potentiometer instead of sensors and when the output is high or density is high that lane gets servicing.else when values are low then sequential operation occurs. a manual switch or emergency switch to let a lane in emergency and after every 2 min all lanes are closed for 30 sec to alloow pedestrians. ....etc
