In Automation Studio, is it possible to have multiple connections to one device through EtherNet/IP? Help file leads me to think it’s possible but I can’t find how to do it. I navigated every section I could think of and also tried doing it using a Generic Module instead of the EDS file.
Hello Sandro,
Welcome to the B&R Community!
You can have only one (1) Exclusive owner (EthernetIP implicit connection with inputs and outputs) to any EthernetIP adapter. You can have multiple Listen-only connections (Class 3 implicit connections with inputs only) to an EthernetIP adapter. The connection type can be changed in the Adapter Device Configuration (DTM) on the Connection page. Your top, horizontal red circle changes the dropdown to select Listen-only (currently set to Exclusive-Owner).
This is done to prevent contradictory output commands from multiple scanners, while still allowing another scanner to read information from the adapter.
Thanks for the prompt response @austin.carpenter !

Hello Austin and Sandro,
i want to interface an EtherNetIP Adapter (ifm VSE151) which offers a process-image using multiple input-assemblies and one output-assembly. Am i right that this is not possible with a B&R IF10D1_1 scanner?
i can only select ONE single connection from the dropdown-menu, but i need several assemblies (InAssembly 104+105+106 + OutAssembly 154 at the same time).
Austin, you mentioned that it should be possible to select multiple Listen-only connections? How can i do that?
The entry in the menu is “Connection” and not “Connections”… is this a hint that B&R does not allow multiple EIP connections?
If i can only select ONE connection the process image is limited to 255 bytes.
If i need to read more than 255 bytes from the Slave(adapter), how is it possible?
Any help appreciated,
Best Regards, Albert
