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. How PLC does work? We have to connect the all the input and output devices to the plc module to activate all inputs and outputs by writing program in PLC. The PLC receives information from connected sensors or input devices, processes the data, and triggers outputs based on pre-programmed parameters. Depends on Your requirement you have to connect input and output to accordingly. Let’s if you want to do home automation, then you have to connect the sensor to get light automatic on. Check the connection below. Function Block Of Plc In a PLC System: v   The control program inside the PLC provides the wiring connection between the devices. ...

Memory bits used to control inputs and output signals in PLC In Micro controller based device memory is divided into three category i.e. Program, Discrete or Digital Registers and word. Data is held in these Registers. These  Registers come in different sizes, and hold different kinds of data. Bits or Boolean : Can have values 1 or 0 Condition.  1 is represents On while 0 represents Off.  Bits are the building block for all other types of data. These Boolean values are used for all the input and output devices like sensor and switch inputs, as well as motor or other outputs. Integers (Multiple Bits) :   Multiple-bit integers are usually  8, 16, or 32 consecutive bits and can hold only whole number values. Whole numbers  also Called as Characters (char), Integers (int), long Integers (long int) or Words. Depends on  bit size and whether they are signed or unsigned.   Unsigned  Integers are positive numbers, while s...

            Full Adder Full adder is a circuit which is used to calculate three digits in the form of sum and carry. It will calculate the sum of three bits along with the carry as mentioned below. Full adder can be form by using two half adder circuit to get sum and carry. The main difference between a half-adder and a full-adder is that the full-adder has three inputs and two outputs. The first two inputs are A and B and the third input is an input carry designated as CIN. The Full-Adder is the actual block that we will use to create the arithmetic circuits. 1.We add two half adder circuits with an extra addition of OR gate and get a complete full adder circuit. 2. Twohalf adder circuits added together with a OR gate.                                                           ...

Half Adder Ladder  Representation In This Blog We are going to discuss about Half Adder .An adder is a  digital logic circuit   in electronics that implements addition of numbers. Here we are going to implement Ladder Representation of Half adder.  Adders are classified into two types: half adder and full adder. The half adder circuit has two inputs: A and B, which add two input digits and generate a carry and sum. Half Adder An adder is a digital circuit that performs addition of numbers. The half adder adds two binary digits and produces two outputs i.e sum and carry;                                   1.    XOR- is applied to both inputs to produce sum  2.     AND gate is applied to both inputs to produce carry Truth Table: Ladder Representation...
