S7-connection Fault Tolerance Redundancy (Server - Client Communication)

Dear Support,

Initially I setup as S7-connection in S7 PLC NetPro. When I check the communication for redundancy switchover between the primary & secondary PLC's. I lost the communication on the WinCC HMI. So, I change the setup to S7-connection Fault Tolerance for Redundancy. Then I check the communication for redundancy switchover between the primary & secondary PLC's. No more loss communication.

But I received the following pop up on the screen “SIMATIC NET SOFTNET-IE S7 REDCONNECT V16.0”. See attach.

Is there a way that the Win10 can work without setup fault tolerance connection?

How can I eliminate this pop up in runtime and work normal as redundancy fault tolerance?

Hi, 

Is this (REDCONNECT) license is required for my application. As I'm not using any communication processor card (i.e.) CP 1623 installed in the PC. Network communications are via Ethernet switch.

Is there a way that the OS can work without setup fault tolerance connection?

How can I eliminate this pop up in runtime and work normal as Redundancy fault tolerance?

Hi again,

I believe the same licenses are required, even if you don't use a CP.

The main advantage of using the CP is to process communication data in CP's processor, and not in PC's NIC. This allows you not only to reduce PC CPU load, but also to have more active connections at the same time.

Note: for a long period of time, using the CP was the only possibility to establish redundant connection to 400H.

Hi,

Instead of using fault tolerance redundancy (Without the Simatic Net Softnet IE S7 Redconnect V16.0 software license). Is there a way to do standby backup connection for two PLCs with two IP address (Ex: 192.168.0.1 & 192.168.0.2). If one PLC fails, then other PLC take over as backup connection without losing the communication on the WINCC HMI. 

Thank you
