Damn this dude is giving us a full professional-grade many hours long super interesting education virtually for free and still apologizes like 15 times for making a tiny little mistake. I can't even express in words how fucking grateful I am that you're doing this so I will definitely consider the gofundme option and yall guys should too. Thank you for what you're doing

[@SamSam-it5ht]

Hello. Can you please explaing the exact differences between the local # and Global tags %? I did not get the point as you mentioned, "Local tag is only used in this program". Does it mean that this tag cannot be used in other OBs ? The software does not scan and send bit on this tag?

Thank you guy, your videos are amazing. I have been looking for education like this about TIA for many years and yours is what I was seeking. Compliments for the clarity you use in your videos because I am learning well all about this subject. I hope your channel is going to improve more and more this way.

[@jacquedreyer5479]

Excellent video - thanks. It is also great to see some minor mistakes that is a part of programming and configuring devices. I like this approach much more than highly edited videos that try to create an image of perfection.

[@davidGmuns]

Thank you very much for sharing your knowledge. You are doing an excellent job and I really apreciate it. What we see on your videos is just the tip of the iceberg, but I do know that there are lots of hours behind every single video. One thing more, don´t complain on making mistakes, they will give you (and also to us) the best lessons. Wish you the best! Forward, always forward!

[@chuchuokeke]

Can we say that the add function @20:29 is a system function or system function block? What's the difference? I have seen SFB in older siemens programs...

[@electricalengineers7402]

I appreciate alot for this great knowledge but my question is if you have two programs anolog signal program to operate first and in case it gets a problem the digital signal program to start operating. How do u join these two functions. The program is that the tank is controlled by two input signal which is the primary and digital input are backup in case the analog fails. I will be very grateful for your support

[@abdalhashim9716]

In SR FlipFlop you are Connecting NC of B3 direcly from the supply line. In SR Flip flop if you receive high signal from R side then it will stop giving high output. In Normal Condition B3 is not sensing any object its NC will be high and SR Flip Flop will not work and conveyor will be in stop condition. please explain

[@sohanbaiju9225]

hello, i wanted to compare a previous input with current input. the current input is always changing and the previous value should be the last current value. how can i do it? thank you

[@londonboy9422]

Start button was still false.

hi, I am writing from Azerbaijan. I have a question, How do you choose inout parametr?, I can not understand...Thak you for attention.

[@sithuaung6501]

Please explain how to use clock in this program.

[@Amalokch]

Very very useful. Question: can I update the function “online” without the need to restart the PLC? I am asking because in Allen Bradley there is a similar approach called “Add-on profile”, but to update this you need to make a download and so restart the PLC

[@jamesmp7105]

What is the difference between M "Memory" input and I "Input"? another question is, what will happen if we use the tags (I/o) instead of function inputs (#)? I greatly appreciate your answer in advance.

[@londonboy9422]

An I input refers to an actual input to your plc from a sensor whereas an M input is located only within the plc itself. For instance, it's good practice to link an I input to an M input e.g. if I0.1 is true, make M0.1 true. Then you use M0.1 in your code, if that makes sense. Not sure on the second question.

[@asyraafmdnor3273]

That is good one sir!. Can you please explain more on the function of inOut, temp and return? Thanks

[@hegamurl7434]

Hello Asyraaf, quick explanation on those: 1. InOut: A global tag that you can read and write inside of an FC/FB, has to be connected from the outside when calling the FC/FB 2. Temp: a temporary tag that can be used for calculations inside the FC/FB. Is created everytime when the FC/FB is called by the PLC (so each cycle) and destroyed each time after leaving the FC/FB to save memory 3. The return value is rarely used... When it is used it is mostly taken as a feedback to see if the FC/FB was successfully/unsccessfully executed Maybe I'll make a video on those in the future, stay tuned!

Why not use a FB instead of FC? Could you explain the difference between them? Thanks!

Hi Fabio, the difference between FC's and FB's is actually not that difficult to understand. I will make a video soon on that topic though, as it is a common thing that many people need to know!

Hello, thanks for the great work. Can you tell me if is possible to add those custom functions that we create in a side bar and make a custom category. for example siemens made basic instructions and inside them put math function(add,sub) etc. can i somehow create a new menu there with my own functions and every time i open TIA portal those function will be available like the add,sub etc functions. thanks in advanced!

[@hegamurl7434]

Hi there! Thanks for the feedback! Yes you can make your own functions and put them in "Libraries" which you can even share with your colleagues and everyone else! There is a little tab on the far right side of TIA Portal for this. I'll definitely make a video about it at some time, very important topic!

is there any downside to having functions within functions?

[@hegamurl7434]

The main downside is the rising complexity of your program. But it is common practice to have multiple levels of functions. The maximum depth you can go is ~24, but that depends on the PLC
