Clients and controllers are on the network 1, servers are on a network 2. In the Simatic shell When i select a network card with clients(network 1), communication with the servers (network 2) is lost and vice versa. Maybe I missed some settings, need help. Installed: WinCC v7.5 sp1 upd2, simatic net v16.0

As you have it now, it would not be separated and this may be the reason causing this problem. To add some relevant information, I recommend you to check the following example: - Redundancy in WinCC V7.x and WinCC Professional https://support.industry.siemens.com/cs/ww/en/view/109772627 Best regards, S7-mencey.

Wincc v 7.0 is now installed and everything works, switching between network cards does not break the connection on one of them. I understand that you need to change the structure, but I would like to understand why it is not possible in 7.5 to switch between network cards.

s7-mencey Posts: 71 Rating: (29)	Hello KateT, In the following manual, you can check detailed information about communications with several network cards in WinCC 7.5. Specifically in page 63. - WinCC V7.5: Configuration and communication https://support.industry.siemens.com/cs/ww/en/view/109760748 Page 63: Specifics of Communication for a Server with Several Network Cards Best regards, s7-mencey.
