1.Introduction to PLC

Image
  Introduction This knowledge is meant to supply you with basic information on PLC . Control engineering has evolved over time. In the past humans were the main method for controlling a system. More recently electricity has been used for control and early electrical control was based on relays. These relays allow power to be switched on and off without a mechanical switch. It is common to use relays to make simple logical control decisions.  The development of low cost computer has brought the most recent revolution, the Programmable Logic Controller (PLC). The advent of the PLC began in the 1970s, and has become the most common choice for manufacturing controls. PLCs have been gaining popularity on the factory floor and will probably remain predominant for some time to come. Most of this is because of the advantages they offer. ·            Cost effective for controlling complex systems. ·          Flexib...

5.UP Counter, DOWN Counter, Up-Down Counter

  UP COUNTER(CTU) CTU stands for Count Up Timer, which is a type of electronic timer used to count the number of events that occur and display the result. In a CTU timer, the count value increases by one each time a triggering event occurs, and the timer counts up to a preset maximum value before resetting to zero and starting again. A CTU timer typically consists of a register to store the current count value and a clock input to trigger the counting process. When the clock signal is applied, the counter increments the current count value by one. The new count value is then stored in the register, and the output device such as a display or computer interface displays the current count value. For example, a CTU timer might be used in a factory to count the number of products that pass through a conveyor belt. The CTU timer can be triggered by a sensor detecting the presence of the product, and once the CTU counter reaches the preset maximum value, it can generate an output si...
