Introduction
A set of detailed methods, procedures and routines created to carry out a specific activity, perform a duty, or solve a problem.
What is a system? definition and meaning .
The microprocessor is a program-controlled device, which reads a set of steps to be executed from memory and executes them.
What is a microprocessor?
CPU, RAM, ROM, I/O devices, serial and parallel ports and timers
A microcontroller at-least should consist of:
What Are Different Components In Plc?
feedback
What is the name for information sent from robot sensors to robot controllers?
Generalized measurement system is a system that is comprised of the typical elements of a measurement system. It helps to understand how a measurement system works.
Generalized Measurement System
This is the common Microprocessor Interview Questions asked in an interview. In 8086 carry flag, parity flag, auxiliary carry flag, zero flags, an overflow flag, trace flag, interrupt flag, direction flag, and sign flag are present.
What are the flags in 8086?
low power consumption
Unlike microprocessors, microcontrollers make use of batteries because they have:
PLCs are highly reliable, easily programmable, Small and Inexpensive, PLCs can be designed with the communication capabilities so they can converse with the local or remote computer, They can sustain in robust environment less maintenance.
Advantages Of Plcs Than Hard Wired Relay?
roll
Which of the following terms refers to the rotational motion of a robot arm?
The system used for controlling the position, velocity, acceleration, temperature, pressure, voltage and current etc. are examples of control systems.
What is control system
LIFO (Last In First Out) stack is used in 8085.In this type of Stack the last stored information can be retrieved first
Which Stack is used in 8085?
fetch,decode,execute
What is the order decided by a processor or the CPU of a controller to execute an instruction?
The general language program consists of Ladder Diagrams. Relay logic control scheme is represented in Ladder diagrams. Alternative languages uses Boolean representation of these control schemes as base of the computer representation.
What Is The Programmable Language Used In Plc?
work envelope
What is the name for the space inside which a robot unit operates?
Then an Open-loop system, also referred to as non-feedback system, is a type of continuous control system in which the output has no influence or effect on the control action of the input signal. In other words, in an open-loop control system the output is neither measured nor “fed back” for comparison with the input.
What is an open loop system?
The processor made of PMOS / NMOS / HMOS / HCMOS technology is called 1st / 2nd / 3rd / 4th generation processor, and it is made up of 4 / 8 / 16 / 32 bits
What is 1st / 2nd / 3rd / 4th generation processor?
4,8,16,32 bits
How are microcontrollers classified on the basis of internal bus width?
Programmable Logic Controllers are industrially hardened micro computers, designed to replac e electromechanical relays, used to control machines and processes.
What Is A Plc?
degrees of freedom
The number of moveable joints in the base, the arm, and the end effectors of the robot determines_
A closed loop control system is a set of mechanical or electronic devices that automatically regulates a process variable to a desired state or set point without human interaction. Closed loop control systems contrast with open loop control systems, which require manual input.
What's a closed loop system?
Three Logic Levels are used and they are High, Low, High impedance state. The high and low are normal logic levels & high impedance state is electrical open circuit conditions. Tri-state logic has a third line called enable line.
What is Tri-state logic?
because they are not meant to do a single work at a time
Why microcontrollers are not called general purpose devices?
DCS is used for interfacing and computing functions and also provides the means of communication between the other devices. It consists of local control unit, low level interface, high level interface, shared communication facility Etc.
What Is The Significance Of Dcs?
controller
Which of the basic parts of a robot unit would include the computer circuitry that could be programmed to determine what the robot would do?
