Programmable Logic Controller (PLC): PLC is a specialized computer used in industrial segments to control machines and process. PLC is program that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks. The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC. When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes. The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by controlling programming language. Set-point: Set-point is a component of closed-loop control system and abbreviated as SP. It refers to the input which determines the operating point for the process. In industrial systems, the determined set point can be limited by physical or process restraints.

⚫ your circuit diagrams for your basic bricks, such as AND, OR, XOR gates and 1 bit multiplexers, ⚫ your circuit diagrams for your extended full adder, designed in Section 1 and ⚫ your circuit diagrams for your 8-bit arithmetical-logical unit, designed in Section 2. 1 An Extended Full Adder In this Section, we are going to design an extended full adder circuit (EFA). That EFA takes 6 one bit inputs: aj, bj, Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit outputs: sj, Cout and rout. The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only on t₁ and to in the first place: t₁ to Description 00 Output Relationship Ignored Inputs Addition Mode 2 Coutsjaj + bj + Cin, Tout= 0 Tin 0 1 Shift Left Mode Sj = Cin, Cout=bj, rout = 0 rin, aj 10 1 1 Shift Right…
