a question.
but why should I pay for the programming software in a CoDeSys your emoR8 board i2c?

Finally another user with the same problems ..... unfortunately !!
They're in your same conditions with the DS18B20 and so with I2C emo-R8 ..... nothing works !!
I contacted him the UNIPI software developer for CoDeSys it and in the end I should 'I' € 350 for code development for the management of EMO-R8 even I were unipi tecknology !!.
For the speech of the DS18B20 put down the cravings, I think you address anything in CoDeSys !!
If you try Mervis, that I do not like at all, you'll see that everything works also DS18B20 !!
The fact is that the unipi software CoDeSys was created (cososo.eu.uk) without any compensation from unipi so I think you will have to change course.
At the moment I'm looking at monitor of Arduino Controllino which also shows a much better container of unipi, is programmed with Visuino.
What is holding me back is that unlike CoDeSys Visuino not generate the web part to control.

Codesys I find it a bit slow in programming but fantastic from all points of view but, unfortunately, not compatible with unipi

Good luck, Alberto

Excuse me but you, why should I ask CoDeSys?
you have not developed UNIPI for CoDeSys?
Then you should have to implement your cards or not?
Why CoDeSys?

RJ45 ??
I have a RJ11 connector !!

ok,
but in CoDeSys which imposed the address?
The address should be set to the page I / O mapping?
I have tried to set under address% QB1 but when the active output of the relay unipi 1.1 vibrates.
How should I set the address if the emo r8 is set to address Hex 21 or 33 Dec?

Thank you, Alberto

But there is no CoDeSys device for emo r8?

In CoDeSys only it works unipi 1.1 card.
In CoDeSys the expansion board i2c to 8 relays and 1wire bus DO NOT WORK !!

@Alberto-Cauzzi
this project is for raspberry not for unipi and not work with sensor connected on 1wire unipi port.
The error is only bad image reference
