TIA Portal: FC's and FB's When and How to use them and what's the Difference

[@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

[@aldobairovith7834]

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

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

[@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!!!

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.

[@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.

Hi and thank you a lot for your hard work . I have a question, when you add the volume part to the "unicorn FB" this not made all the other glasses have the same volume part? I checked my instances after this and all of them had the volume part not just the "unicorn". I did a mistake ?

Can we define FC block local input and output in DB not FC decoration table possible?

[@johnkamke6192]

Hello, I am still a little confused about the difference between FC and FB. What happens if I create a program for the glasses (your example) using a FC? What is the problem? Will some values disappear? I have been creating programs using both FC and FB, but I don't really get the difference because they always work the same way. That's why I don't understand when people say that FC doesn't have dedicated memory and FB stores the values permanently in data blocks. For example: I created a program to count the minutes elapsed after a condition becomes true using FC. It worked. The minutes value kept going up. If FC doesn't store the values, how did the value keep going up? Could you help me with these question? Thank you!!

[@zinger2225]

I think you didn't use any temp variable inside your FC, and all calculation are based on the "input" or "InOut" variables.So you didnt notice any different. The benefit of FB as i supposed to understand from this great video is the static variables inside the FB, which can be used from one cycle to another.

Hello Is there video about profinet read RDREC instruction. I have no idea how to use it but my project use profinet gate converter.

[@RyderDK]

Thanks for the video. I'm curious as a beginner at PLC programming, and does using a function block provide the capability of stopping a process and restarting it from the exact point it was interrupted?

[@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

[@Bosanac_99]

Does it mean that we could use FB instead of FC blocks in previous example of TV remotes only if there's a many of the same types of TV remotes but slightly different versions? :)

[@TheSidre]

Clearly understand this lesson, thanks.

[@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?

[@ahmedamaar3228]

why at using FC in cpu 1500 the latching can not work in other words when an bool input is denergised the output is denergised although i have latched the output. but in CPU 300 it works correctly

Great question

[@hanlietaljaard261]

Hi, I have a Question.... For using the FB and FC as showed in your video and lets say you have a FB with a input "Change Allowed" as an input, now you call the block and you have created an instanced for that FB... Here is my question... that input "change Allowed" can one use that same input for another block lets say FB3 , Can one then pull it in from the Db Instance? is it allowed? can it work like that? OR do you have to create one for each FB? if so at the end you have 10 mil. of the same input how will it be linked as one at the end of the day?
