I'm using xPC Target (5.2), and I'm running into an issue when trying to configure multiple NICs for use with real-time UDP. I could just use 1 NIC with an ethernet switch, but I'm trying to make very sure that no packets get dropped, while using a 1ms clock. I've got 2 dual-port (i.e. 2 ethernet jack) 100 Mb/s NICs plugged into the target PC's PCI slots. I tried to use 2 of the Network Configuration blocks from the Real-Time UDP library, and everything compiles and downloads just fine, but when I run it on the target, I get the following error:
"EtherInit: EtherID 1: Registration Error 2
ARP: Invalid IP Interface 0 (1309)
IP: Invalid IP Group 0 (271)
UDP: Invalid IP Group 0 (113)"
However, each card works fine when only that card is configured. I also tried having both connections on the same dual-port NIC, as well as having 1 connection on each card. Is it even possible to do Real-Time UDP with multiple NICs, or do I need to use the Raw Ethernet library?
Thanks so much,
