The 7.7 gateway status is faulted on a fresh install of Ignition 7.7 on Ubuntu 14.04 x64. This is the installation script I used that worked fine for 7.6.6.
I followed the guide in the above link but the KepsreverEX connection status was still in fault. Then i tried the following:
The default ip address on the Configure/OPC-UA/settings page was incorrect. Changed it to Ubuntu server ip address 192.168.1.2. Check screen shot 1
The default ip address on the Configure/OPC-UA/certificates page was incorrect. Restarted ignition, ip address automatically updated, regenerated all the 3 certificates, downloaded the client certificate and finally imported into KepserverEx trusted clients page. Check screen shot 2
Turned off W7 firewall, edited and saved the OPC server connection page and the status changed to CONNECTED. Check screen shots 3, 4 and 5.
In the W7 firewall page, allowed the program “server - runtime” from the “C:\Program Files\Kepware\KEPServerEX 5” folder to communicate through Windows firewall. Turned on W7 firewall.
Kepserver trusted clients page for my above post. Pls note that i have 2 clients.
“ignition 7.7/32bit/windows” on my W7/32bit local machine (192.168.1.7)
“ignition 7.7/64bit/Linux” on Ubuntu 14.04/64 bit server (192.168.1.2).
Both OPC-UA clients work fine.
Note:
Make sure that the “Endpoint Address” in the “Configure/OPC-UA/settings” page has the local Ignition server ip address. In a headless Ubuntu server/64 bit installation, it does NOT update the server ip address automatically. Needs to be edited manually, restart ignition and reinitialize Kepserver.
After this, Kepserver identifies automatically all the ignition servers running on the LAN in the trusted clients page.
