The answer is equivalent to 1, not 2 because we still follow the Binary number system.The knowledge of Input Devices helps to imagine a multitude of solutions to a common problem, as well as knowing the different Output Devices that are controlled by the PLC to solve the problem in the first place.This means that the final outcomes must be determined clearly along with the conditions that determine the outcome.
Ladder And Functional Block Programming Logo! Full And ThenYou want the tank to fill up until it is full and then automatically refill one the water level is near empty just to maintain the pressure.
Lastly, you would want to control an input valve to regulate the flow of water into your tank. Logic circuits are digital, so they produce outputs that are discrete in nature. This means that its either True or False, High or Low, Yes or No, 0 or 1. Nothing in between. This simplifies input-output relationships as compared to the analog side of things. The Maybe in between the Yes or No, or the Medium in between High or Low. ![]() Confused For a single digit, BI (two)-nary means two possible outputs. The Decimal number systemwhich we are familiar with, has 10 (prefix Deci-) representations: 0, 1, 2, 3, up to 9. In decimal, you use 10 if you have exceeded counting through all representations (0 to 9) once. The way they did this is by using the binary logical operations: NOT, AND, OR, XOR, NAND, NOR, and XNOR. If you have 0 as an input, performing the NOT operation will output a 1. The logical operators that I will discuss next require 2 inputs. This decreases the possibility that the operator has his hand placed on the drilling platform while the drilling operation starts. In comparison with the AND operation, you can only turn on a circuit by turning BOTH switches ON. In the OR operation, relays are connected in PARALLEL to each other. This means that the input must be different from each other, hence the term exclusive. Comparators, as implied, compares two input signals and sends an output signal based on predetermined criteria or functions. In this case, the comparator outputs a HIGH signal when the inputs become different. ![]() But, it is still helpful to have a basic understanding of them. Ladder And Functional Block Programming Logo! Series Of LogicalBoolean Algebra provides a way to simplify even the most complex series of logical operations imaginable.
