Hi,

thank you. It is better now.

One more question about programing... how to retrive the temperatuer from sensor?
I can read few parameter except temperature value.

It looks that the issue I have is related to the /boot/config.txt file (dtoverlay=w1-gpio). Is this OK?

Thank you in advance.

I must have missed this post somehow.

The most likely cause is that the variable that the channel is mapped to has been optimised out because it is otherwise unused.

Thank you for posting the resolution, I am sure others will find this helpful.

Please note that this is expected behaviour when using any CODESYS project with different versions of the devices to the ones the project was developed with. The template project that is part of CODESYS for UniPi was developed with a particular version of CODESYS, yet will work with many different versions just by updating the device as shown. The project and package are only updated if there is an enhancement or a bug fix.

Once you have created a project, if you wish to update to a new version of CODESYS for Raspberry Pi, or CODESYS for UniPi you would need to update any changed devices in the same way.

I hope that helps explain why the step is required.
