As usual an absolutely good lesson. You understand the difficulties of the lerners. You are a good teacher. Many thanks Sir.

[@jordanj3880]

Great video sir. I usually can't bare to listen through the lessons of most PLC channels on here, but you nailed it. Keep up the great work, it's opening doors for many people's futures

[@realstinga23]

The part where you explained the ADD as an FC and timer as an FB really drove it home. Thanks!

[@walid5419]

I was learning about Function Blocks and this is by far the best demonstration and how to use them. Thank you

[@АндрейШабалкин-б4я]

thank you for your lesson!!! it's easy way to get that difficult information!!!! you're the best teacher!!!!!

[@JasonFerguson-hg5mp]

I have studied the things you covered in this video in my past and I thought I understood but... several things you did in this video was so helpful, like the top In/Out, when you gave this example a visual real world application I understood it so much better. You are a great teacher on these topics and I have learned so much today since I found your videos. Thanks for your way of presentation and please let me encourage you to keep it up because you have encouraged me. Great job!!!

[@sofianetidjani]

I appreciate the endeavor you spent in selecting the right concrete examples to explain and fix the ideas of FC and FB to us. ALLAH bless you.

Thanks! Very helpful!

[@bestyav5529]

Frankly speaking May God grant you long life to teach these stuff. FC and FB notion was fucking vague to me 😂😂😂. Thanks a million... My Brother, I made a simple FC block for automatic up/down counting .then the counter must reset and stop after up/down counting 4times .I'd like to call my FC multiple times. Then for the block to work in OB1 i have parameters to fill: 1) a push button to Enable the Counter 2) counter preset value 3) Counter value which is just a memory to view the count 4) count cycle to define how many times id like the counter to do up/down. But after calling my FC twice as i want to have two different preset values and two different count cycle the system misbehaves😂 i mean there is conflict between counter preset values and count cycle ⭕. How to fixe that??

Hi Philipp, thanks for this informative tutorial! Could you also make content on DBs including advantages of using them with the help of some application example?

Hi Durgesh, Good Idea! I will make one in the future, don't know when yet though. Stay tuned!

hi, can you also make tutorial video using analog output signal for example is a filling tank using potentiometer. your video is always worth watching, keep it up because I learned a lot from your video...thanks a lot

[@hegamurl7434]

Hi Gwen, I actually had in mind starting an "Analog Signal Processing" series... as the topic is quite complex, I'll most likely split the topic up in several parts. Thanks for the feedback!

[@alial-shaibany7571]

[@babakqomi6731]

Amazing

[@michalinasredniawa5512]

I love You, great job!!!!!

[@RabbiEEE]

This is how good geeks present complex things easier. I've a question, How FB takes input variables ?

[@schievel6047]

Im not entirely sure if I understand your question, but if you are asking wether an input is called by value or by reference ist really depends. On FBs elementary types (bool, int, real etc.) are always called by value. Even when they are given as an InOut Then the value of that variable is read, the FBs code is executed and the value is then written back to that variable. Combined Types (Struct, UDTs, Arrays) are called by value as Inputs and Outputs but called by reference as InOuts. On FC on the other hand, this is different. For an FC the combined types are always called by referenc, independent from if they are called as Input, Output or InOut. But since this is Siemens, there cant be a rule without an exeption, because of downward compatibility: Is one of the Blocks, the calling or the called one is a optimized block and the other one isnt, all combined types are called by value.

[@daviderhahon]

@@schievel6047 Thanks. But I'm thinking..... For FCs to take in an input variable during execution, you have to specify an input address (Eg i1. 0, i3. 1). However, For FBs, how do you specify where it takes its inputs from? Eg. Where would Unicorn glass derive it's Fill-In value from? (and Take-Out value too).

[@mpahanesabata4730]

This is very good, thanks man

[@abedal9206]

Thanks man for the video. I have a question though, can I use a timer inside a FC (Function)? And how would it behave if I use multiple instances of that FC?

[@hegamurl7434]

You are very welcome! If you use a timer inside a Function (FC), you will be asked which "Type" you want to create. In a FC there are two types: 1. Single Instance: All calls would use the same instance, so you could only use it once 2. Parameter Instance: When you call the FC you have to link a new Timer-DB from the outside, so you can reuse it In addition, when you use a timer in a Function Block (FB) you will have a 3rd option: 3. Multi Instance: With each new call of the FB a new Timer_DB will automatically be created inside the iDB, so the easiest reusability

[@kaktus994]

Very nice video and explanation with examples. So, basically, if I got this right, we can think of a function block as a class and DBs act as the instances (objects) of it? And FCs inside of an FB are its methods?

[@szolek8472]

Hello, I have a question, very often I create functions and use them only once in a program, just to divide my OB block into clear parts, in my opinion it makes the program clean and readable. In those functions of course, I use access to global data, PLC tags, etc. I'm not sure if this is correct program structure,? you said that inside of functions we should always use function panel and input/output etc. parameters ? By the way graet job, I really like way that you explain PLC programing.

[@robertlopez3107]

Great explanation. However I am wanting to know about global and local tags, what is the difference?
