Hi,
we really thought one the community could help to implement this.
At the moment it is more or less a problem on the high workload that it is not easy to bring this into the product.
Let me check what we could do. (Have you already tried it?)
Fro my Point of view the bigger problem would be: How to get rid of the predefined functions you have as default on the GPIO's
like I2C / SPI whatever there is mapped to these GPIO's which you want to see additional in CODESYS.
So These are the additional things to do outside CODESYS, do you agree?

I don't really see how a basic functionality of the device should be something for the community to implement, especially for those of us who are paying for licenses. Yes I have actually tried to do this myself but sadly I can not figure it out. I would assume that whoever wrote the code to begin with could probably implement the changes in a few hours vs some random person like me struggling for weeks to figure it out.

On top of all of that I still don't feel like you really understand what we are asking for, we are not talking about the I2C/SPI pins, we are talking about the PINS that don't even show up for use, I thought I made this pretty clear in one of my earlier posts.

EDIT ***
The previous post I was referring to is in this thread

Hi,
I would like to know if this problem with GPIOs for PI3B+ has been solved, since I will need to use all 26 entries available in Raspberry.

No it has not been solved, and so far it has barely even been acknowledged.

Thanks for that. I managed to get it to work once, but its not consistent so I will try your wiring diagram.
###EDIT###
So after a bit of fault finding it seems I cant use GPIO25 as an Input. I was using GPIO4 as Output and GPIO25 as Input. The Output was fine but I had a problem with the input. When I swap them over it works 100%
Any ideas why GPIO25 doesn't register when I use it as an Input?

Honestly I am just pretty frustrated at this point with CodeSys' lack of support regarding the Raspberry PI's GPIO's. I can't believe how hard it seems to be to get a clear answer on why they dont work right, and why not all of them show up. I have a PI3 with GPIO's that I can't even use because they wont show up in the GUI. I have paid for multiple licenses and still have not got a clear answer other than "Go build a new library yourself".

Did you ever figure this out? I am having the same issue and was wondering if I needed some resistors somewhere and whether I should connect the GPIO to GND or to 3.3V.
Anyone have a physical wiring diagram that works with CodeSys?

finally got my inputs working last night... here is the wiring diagram that worked for me.
