Counter and its Function/Automation/Industrial Automation/PLC counter

By Prathima
What is counter A counter may be a digital circuit or device that counts the amount of products and returns predefined values supported clock pulse applications. The output of the counter are often wont to count the amount of pulses. The counter circuit is typically composed of several flip-flops connected within the cascade method. Counter automation and digitally based components are very widely used components.      Micro controller applications require external events or precise internal time delay generation and calculation of pulse frequency as required . These phenomena are often utilized in digital systems and automation. Both of those events are often performed by software techniques, but software loops for counting won't give accurate results, as little more important work isn't done. These problems are often corrected by timers and counters in micro controllers that are used as interrupts. Classification of counters In digital circuits, counters ...

Latching and Unlatching Circuit Using Ladder Logic

By Prathima
 What is PLC A Programmable Logic Controller, or PLC, is a Micro controller Based Device  used for industrial automation. These controllers can make  automatic  for a specific process, machinery, Home Automation  or even an entire production line. Latching is used in plc as well as hardware circuit to make the circuit in continuously on condition.   Latching Circuit in PLC Generally Latching is a circuit used to keep the output continuously in on Condition. Latching is only applicable for the push button or switches which has spring act. When you are using hardware circuit you can use relay or contactors, these two components is used to make load in on condition. In Below concepts we can understand the concepts of latching and unlatching circuit by using switches   Case1: When you are using Toggle switch, latching is not required. Check in below circuit. In this case toggle switc...

Introduction to CSS,Typography

By Prathima
  Introduction to CSS What is CSS? CSS (Cascading Style Sheets) is used to control the style and layout of web pages. It allows you to separate content (HTML) from presentation, enabling better design consistency and easier maintenance. Why Use CSS? Enhances the visual appearance of websites. Makes websites responsive for different devices. Reduces duplication by centralizing styles. Enables consistent design across multiple pages. Types of CSS 1.      Inline CSS o     Applied directly to an HTML element using the style attribute. o     Use When: You want to apply a unique style to a single element. Example: html Code start here <p style="color: red; font-size: 16px;">This is an inline-styled paragraph.</p> 2.      Internal CSS o     Defined within a <style> tag in the <head> section of the HTML document. o  ...
