Replacement of LCLiScUINT() function block in AS6

Hello!
I am trying to convert AS4 project to AS6. I realized that there is no LoopCont - LCLiScUINT() function block existing in AS6. I am doing a scaling or linearization of analog integer values from sensors.
Is there some replacement for it?

Thank you!

LCLiScUINT()

Hi Andrej,

Please take a look at Marcel’s answer on an earlier post for some suggestions.

Thank Marcus, but I think that I cannot find same functionality in MTBasics. But just to mention I am rookie at programming. :wink:

Hi Andrej,

depending on what you trying to do here are some options you should take a look at.

MTBasicsLimiter

MTHydValveLinearization

LCRLimScal()

MtLookUpTable would also work.

Thank you @marcel.voigt. LCRLimScal() will do the job. I just need to convert INT to REAL beforehand.

Thank you again!

Hi @Kolma

a heads up: when searching for the FUB you might not come across the landing page of the library that contains it: B&R Online Help
→ “This libary is replaced by the Mechatronics libraries.”

I recommend to not use that specific FUB so you won’t have to do it all over again once the FUB becomes unavailable-

Best regards

Hi @michael_w

Which FUB should I use as a replacement for LCRLimScal()?

Thank you

Hi there,

unfortunately it looks like this FUB has no successor.
Maybe if I have some more time I can whip up a small method, but this should only be a small method to implement on your own - that would be the most future-proof way I guess

Best regards

Hi @michael_w

No worries, I can implement it myself. But thank you anyway :slight_smile:
I’m just a bit annoyed, that there is no replacement in the successor library.
And according to the linked post, I’m not the only one.

Best regards

So, LoopConR is supported under AS6 but LoopCont is not?
We have a library which uses LoopCont extensively. Replacing all those functions and function blocks is really tedious…

>So, LoopConR is supported under AS6 but LoopCont is not?

yup, this is what we have. My question is: “Are we sure the new libraries will cover all use cases implemented with LoopCont?“ I’m sure there is a gray area where in some cases the new code will require additional time for testing all cases.

Hi,
since this topic has come up a view times I would like to share some official note to this issue. The note in the help file exists since AS4 and does not mean that the LoopConR is discontinued in AS6. It is just a reminder that there is a more up to date mechatronics library. There is no plan to discontinue the LoopConR in the near future and it will also be available beyond 2027 when CRA hits.

As with all software components we can not provide any guaranty for how long the library will be available but it will not be discontinued any time soon and it can be used as 1:1 replacement for the standard LoopConT.

Happy coding

Stephan
