Essentially, a PLC's operator draws the lines and devices of ladder diagrams with a keyboard onto a display screen. The resulting drawing is converted into computer machine language and run as a user program. PLC will operate any system that has output devices that go on and off (Discrete, or Digital, outputs).
Develop PLC Programming Batch Process ladder logic program according to the logic given below, Ingredient A is sent to the tank first by energizing solenoid 1. The flow meter gives one pulse for every gallon of flow. Solenoid Valve will be open until 200 gal has poured in. After ingredient A is in the tank, 200 gal of ingredient B should be added.
This paper introduces X-machines, a state-based formalism, to consistently model and verify PLC ladder diagrams. X-machines model control and data flow unambiguously, and have associated with them a test set generation method that is amenable to automation.
