IRT Can not tick box

Hello all,

I would like to setup an IRT communication, but I'm not allowed to tick the box in the picture, why? What do I need to do?

Would you kindly post a screenshot of the topology view to see the interconnects?

Hello again,

Thanks for the answer. I include a project with the setup. I would like to communicate with IRT to the node and the DI IO. But I can not tick the box and I get an error when I compile. 

Thanks Beginner23

Hello,

this is because your Interface module does not support isochronous mode.

For that you need a ET200SP HF or HS Interface module.

Thanks! 

But it support IRT? What is the different between IRT and isochronous mode?

Hello,

this means that you can use this device in IRT Networks because the Chipset can work with IRT Frames but the device itself can not work isochronous.

It is similar to the differences in G and S control units for SINAMICS drives.  Both can participate and pass IRT profinet traffic. However, only S drives can operate in isochronous mode.
