I am a bit new to OPC, and so I am trying to test some connections and see how they run. Inside an internal network (home based lan), I have the Ignition OPC server running on a desktop. The IP address for the desktop is 192.168.254.115. I have started a project using the simulated PLC driver.
By the way, I have installed this on a linux desktop, running openSUSE 12.3. The networking issues should be basically the same, I think, as any other platform.
When I open the gateway and go to Configure -> OPC-UA -> Certificates, under “This Gateway”, it has my ip address listed as:
IP Address 192.168.1.101At one time, I think before I installed ignition, I did have the local network with the ip addresses using 192.168.1.xxx instead of 192.168.254.xxx.
My ifconfig status shows:
eth0 Link encap:Ethernet HWaddr 48:5B:39:38:8A:57
inet addr:192.168.254.115 Bcast:192.168.254.255 Mask:255.255.255.0

My goal is to be able to connect to the gateway from a remote pc on the same lan. My laptop, which connects by wireless, has an ip address of 192.168.254.118.
Is it possible to connect to the gateway by the lan? I have been assuming that I should do this before I try and connect a client remotely through the lan.
Do I need to force the OPC-UA server to be set up on the correct ip address? I don’t know why it picked up the old addressing scheme.
Thanks for your help in advance.
