Hello,

I have customer that would like to connect an IRB 1600 to a Fronius weld machine. I’m not super familiar with the Fronius machines, but the examples I have seen have been connected to robots with Ethernet IP or EtherCAT.

The customer’s IRB 1600 has the following control module options:

701-1 FlexPendant: FlexPendant 10 m  
888-2 PROFINET IO: PROFINET IO m/s SW  
1541-1 Base Dig. 16In/16Out: Base Dig. 16In/16Out 1  
731-1 Safety interface: Safety internal conn.  
733-1 Operators panel: Panel on cabinet  
735-3 Operating mode selector: Add. Contacts, 3 modes

So my question is, does option 888-2 (without 841-1) prevent me configuring the LAN/WAN ports for Ethernet IP?

Which option is 841-1? Some years back I had used the LAN to connect both profinet and the plant network, just assign a different IP. However, look around on this forum some more, I believe that we had a discussion in which someone (DenisFR?) said that such is no longer working on the newer robotware.

Hello,  
Yes, since some years, when ProfiNet is activated on an interface, you can’t use any other protocol.  
So for you, if you activate ProfiNet on LAN3, you have to use Ethernet-IP on WAN. But don’t connect them together…

Thanks Denis. Maybe he can, he did not mention which version of robotware they are using.

Sorry for the late reply, but yes Denis was Correct. Thanks for the responses. Customer was using 6.10
