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. please help me to find the problem. best regards.
