Hi all,

I'm in trouble with the setting of a PC-Panel with WinCC RT Advanced V16.

On my plant there is a TP1900 that is working connected to two PLCs in different networks, NW1 is on IPs 172.16.20.xxx (with IP 172.16.20.4) and NW2 is on IPs 172.30.41.xxx (with IP 172.30.41.10), NW1 is connected to X1 and NW2 to X3 of the TP; with this configuration everything works well.

Now I'm trying to add a PC with the same software (with the modify for RT Advanced) but I can connect only to one PLC. The new PC has 3 network cards,  two Intel I210AT and one 8111E.
I've correctly set the IPs on the cards and I can ping all the PLCs in the two networks, from the programming pc when I connect to 172.16.20.xxx I can Ping the PC (172.16.20.5) and on the 172.30.41.xxx I can ping 172.30.41.12.

The issue is with Runtime Advanced software, where, in hardware configuration I've set 2 IE General cards, with IP configuration as the hardware, but only the first one communicates with the PLC.
I've tryed also to exchange the configuration, both in hardware and in Connections and I can always use only first network, I think I'm doing something wrong but I can't understand what.

All suggests are well accepted.

Thanks in advance.

Have you configured s7online1 as a valid pg/pc interface from your set pg/pc interface in the control panel?

If you havent go to control panel without any tia portal open or any wincc rt application running then go to the dropdown list at the upper part and the press add/remove add s7online1 and then put it to connect on your second ethernet adapter.

Thanks a lot, that solved everything!!!

I think that on TP this is automatic, I've added ONLINE1 in pg/pc interface and it worked at the first start.
