Deductive reasoning Deductive reasoning Deductive reasoning, also deductive logic, logical deduction is the process of reasoning from one or more statements (premises) to reach a logically certain conclusion. Deductive reasoning goes in the same direction as that of the conditionals, and links premises with conclusions. If all premises are true, the terms are clear, and the rules of deductive logic are followed, then the conclusion reached is necessarily true. Deductive reasoning (""top-down logic"") contrasts with inductive reasoning (""bottom-up logic"") in the following way; in deductive reasoning, a conclusion is reached reductively by applying general rules which hold over the entirety of a
State logic State logic A state logic control system is a programming method created for PLCs. A state logic control system uses a state transition diagram as a model of reality, thus using the fundamentals of finite-state machine theory as the basis of a programming language. State logic enables users to model the application they are trying to control by using a hierarchy that consists of Tasks, subdivided by States which are described by Statements. 'Tasks' are a description of a sequential activity of the model. The machines, applications or processes being modelled by state logic will usually contain more than one
