I’m configuring Ixxat SG-gateway with PROFINET (the one with only 1 Ethernet port).
From Ethernet side it is connected to switch and have IP address of 192.168.0.15. There is also the second identical Ixxat module with IP 192.168.0.14.
From Profinet side it is connected directly to test PC 192.168.1.10 (we hope so, but have some doubts now). We use upper Profinet port configured from Ixxat setings page as 192.168.1.15; 255.255.255.0, GW 0.0.0.0. Port indicates green after connection of Ethernet cable. The problem is that I can’t ping the device on Profinet port from test PC. I also used Profinet commander to search for module, it doesn’t apear in the list.
What I found today - when I change test PC IP to 192.168.0.10, I can ping both - 0.14 and 0.15 Ixxat modules. Is it possible that Ixxxat Ethernet port has internal switch to Profinet ports? We are 99.9% sure that test PC is connect only to Profinet port, but why I can ping all LAN devices connected to switch? There is stil 0.1% chance that test PC is connected to switch instead to Profinet prot, but before we send someone to verify it in place, it will be good to know that Ixxat is able to make such internal switching.
Of course all settings ae properly saved, module was rebooted several times, Ixxat log shows that Profinet IP is set properly etc.
