I have same problem, I have a 6ES7 155-6AU01-0CN0 module and want to insert a BA 2xLC-LD 6ES7 193-6AG50-0AA0 module, but I’m not able to insert anything else then the standard 2xRJ45 module?

Have tried to make a new empty project with only the IM155.

TIA Portal V19 update 3

------------------------------------------------------------------------------------------
Split from How to add Bus Adapter in Hardware Config.

Firmware version is 4.2, so that should be ok.

Where can port monitoring be disabled?

Here I have removed the interface and is trying to drag and drop the new interface, but this is not allowed.

Here I try to replace the interface, but ok is not available if anything else than 2xrj45 is selected. Is it normal that version is 0.0?

At this moment the Et200Sp is not connected to any CPU in the application.

In attached "SafetyCommunication.png" is the network layout of this small project.

I was blind

I didn't notice that it should be configured as 2xLC not as the actual 2xLC-LD even if you wrote it here and it says so on this page
