Chapter 1, Problem 20RQ
Program Plan Intro
Programmable Logic Controller (PLC):
- • Programmable Logic Controller (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 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 control
programming language.

Each register is 16 bits long. The required transfers are dictated by four timing variables, T0 through T3 as follows: T0 : X←A T1 : X←B T2 : X←C T3 : X←D The timing variables are mutually exclusive, which means that only one variable is equal to 1 at any given time, while the others are equal to 0. Draw a block diagram showing the hardware implementation of the register transfers. Include the connections necessary from the four timing variables to the selection inputs of the multiplexers and to the load input of register X.arrow_forward
