Automation studio B&R PLC ST programming PART 13 - WHILE .....DO LOOP for finding highest value.

Image
 While do loop is used continuously monitor a condition, if the condition is fulfilled the statement insdie the loop is executed. Otherwise it will jump out of loop. In  tutorial the while is continuously monitoring the Array J[i] which is having integer value, and displaying the largest value. Download Prog file from below drive link:- https://drive.google.com/file/d/1bzc0gqOsBHh_NUvumjbhzAdq090prK-4/view?usp=sharing Explanation:- Below is the flow of While do loo[ for Program execution:- Below are the variables used in While loop example:-

Industrial Sensor Part 6 ( English Audio )- Ultrasonic Level Sensor Selection Parameters

Image
 This Video Tutorial is about, the parameters to consider while selection of Ultrasonic level sensor from Manufacturer Datasheet. Click Below for Video Tutorial Ultrasonic selection video tutorial Explanation:- 1. Agenda 2. Material /Product:-     Material or product for detection is to be first considered. For Foam forming liquid we cannot use Standard Ultrasonic Level sensor, we have to specifically use Guided radar Sensor. Guided Radar sensor consist of Probe and emit sound which would help for successful detection of liquid from foam. While Standard ultrasonic sensor only Sound for detection. Standard ultrasonic sensor can be used for detection of water, sludge & High Viscous Materials. 3. Output:-   Usually ultrasonic level sensor comes with analog output    A. Analog Wired Output    B. Analog Wireless Output A. Analog Wired Output -       0-10V DC and 4-20mA are mostly used in industries. 4-20mA are less prone to interference and can travel to more distance tan 0-10VDC    HAR

Automation Studio B&R PLC Part 10 - Using 'CASE Statement' for programming Complete Tank Level Logic in ST

Image
This tutorial is About Learning how to use CASE Statement for Programming Tank Level Logic. CASE Statement are widely used as it helps for easy programming. Click Below for Video Tutorial:- Case statement Video Tutorial CASE Statements are also Called Switch Statement in C++.  Case Statement acts as a switch. We can switch between Staements. Benefits of Using Case Statements :- 1. Better than Cascaded IF else statements. 2. easier to understand 3. Faster execution than IF Statements as CASE acts like a switch.  Syntax:- Explanation:- 'Casename ' is similar to variable name ( user can define any name ) 'Statements' is also similar variable name (user can define any name ) Statements consist of  Logic. we can switch between Different statements i.e switch between different logic. Statement 1 is Executed first when CASE is executed. In statement 1 user have to specify other statements to jump in form of Logic Please watch Youtube video below which would make understand bet

Industrial Sensor Part 5 -Ultrasonic Fork / Slot Label Sensor working, Pros-Cons, Application, Frequent Question on Selection.

Image
This Video tutorial is about Ultrasonic Fork / Slot Label Sensor working, Pros-Cons, Application, Frequent Question Click below Link for Tutorial Ultrasonic Fork / Slot Label Sensor working, Pros-Cons, Application, Frequent Question Slides:-  Ultrasonic Fork Sensor are used for label detection Ultrasonic Fork Sensor is a thru beam type Sensor. It has transmitter and Receiver. Sensor detects label on difference between Sound received at receiver end from label and label carrier. Color independent - Ultrasonic Sensor can detect any color or transparent objects as it detection is based on Ultrasonic sound. Label gap independent - It can also work in variable gap labels. reflective/Glare independent - Ultrasonic sensor is independent of glare in label or carrier unlike Photoelectric . Ultrasonic Sensor are less accurate than capacitive sensor, as capacitive sensor detects object based on dielectric thickness of label. Basic ultrasonic sensor fails for multilayer labels. Unique type multila

Industrial Sensor part 4 - Ultrasonic Sensor Selection Parameters as per Application

Image
 This Video Tutorial is About Selection parameters as per Application of Ultrasonic Sensors. Click Below Link for Tutorial Selection parameters as per Application of Ultrasonic Sensors Slides:-  This tutorial is About basic Selection parameters to consider while selecting any Ultrasonic Sensor.  Not Specific to any type ( Like Level, fork etc ) Above are Basic Common Quick Point consideration while selection of any Ultrasonic Sensor.   PNP output is the Signal Which Give ( + V) Output to PLC or Controller. NPN Output is the Signal Which Give ( -  or 0 V) to PLC or Controller. Sensor Selection must be done in Basis of PLC or Controller Input, if PLC or Controller require PNP input Signal than PNP output Sensor must be selected and Vice versa. We must Know the Response time of Sensor required before Selection. Means, If we have ultrasonic Senor operating at 400Hz that Means. response time = ((1/400)/2)= 1.25ms.  1.25 ms can also be said as total processing time sensor required to generat

Industrial Sensors Part 3 - Ultrasonic Sensor Pros cons ( Advantages & Disadvantages )

Image
 This Video Tutorial is about Advantages and Disadvantages of Industrial Ultrasonic Sensors. Click Below Link for Video Tutorial Advantages and Disadvantages of Industrial Ultrasonic Sensors. Slides :-  Before selection of Sensor User must be aware of Disadvantage   Ultrasonic Sensor cannot be used in Vacuum as sound cannot trael in vacuum. this type of Sensors cannot be used in Lyophilizer and Vacuum tray drier. As these machine work under Vacuum to attain specific temperature for Vail or Pharma Medicines. We cannot use ultrasonic sensor where detection is to be done under vacuum. Inductive sensor is used for detecting Metal objects whereas Capacitive sensor is used for detection of Dielectric objects. UltrasonicSonic Sensor can Detect both Metallic and Non Metallic Objects Both. As Sound is used as a medium. Photoelectric Sensor are more prone to Dust and Moisture. Dust and Moisture gets deposited in Lense of Photoelectric Sensor which may cause problem in detection. Ultrasonic Senso
