hello! I have two network adapters in my xPC target which both of them are Intel-Gigabit(82540EM). when I try to boot the system and load my model on target machine, I have no problem. but when I run the model, It stopped in running mode and the connection between host and target failed. (TCP/IP connection disconnected). I check the setting of the network configuration and set it's parameters as follows: IP address : 192.168.4.105 subnet Mask : 255.255.255.0 Gateway : 192.168.4.1 Ethenet driver : Intel Gigabit PCI bus: 2 Slot: 3 when I changed the secondary adapter card and useed a 8255x card, program was completely executed and had no problem. but I need to use Intel-Gigabit as a secondary adapter. Is there any way to configure the system(software and hardware) where I will be able to use an Intel-Gigabit as a secondary card in real time udp applications? Is it possible to exist any inconsistency between my network adapters and other hardwares in my system(like mother board, ram ...)? Can you prefer any hardware setup for optimum performance in the applications that real-time udp is needed? best regards.
