manager configuration in redundant projects

[Houns]

Hello,

I have some questions about the correct configuration of the managers in a redundant project.

1. S7Plus driver
   If I have understood the principle correctly, there is a S7Plus driver on every redundancy partner.
   Both drivers send their data to the respective Event Manager.
   But on the passive system they are discarded.
   Is that right?
   
   But now the system switches to the second host,
   no more values are read by the PLC. And all values set by the visualization are marked as invalid.
   Regardless whether I switch manually via "Force" or simply disconnect the network connection.
   
   Furthermore, I don't see any status of the driver in the driver view of the system manager.
   
   What have I configured incorrectly?
   
   Some screenshots for better understanding are attached.

• Redundancy Manager
  Do I have to define different numbers for the "Redundancy Manager" on the two hosts?

• localhost
  When starting the project on one Host while it already running on the other, there is a message in the LogViewer:
  "The Manager localhost is already running at host $2., MAN: (SYS: 0 Ui -num 100 CONN: 2(R))
  
  Do I have something in the configuration?

Note:
In the trend view within the screenshots the blue curve is a value read from the PLC and the red curve is a set point value modified via ctrl script, but also connected to the PLC.

1. As a first check you can check if the S7 driver works if only the host 2 is started.
Possibly the problem is that the there is no _2 datapoint existing for the S7 connection. Maybe you have configured the S7 connection while the project was not configured redundant and therefore the _2 datapoint is missing.

2. The redundancy manager must be started without a number.

3. For the UI started with -num 100 please check if you have started a UI with the same number on another machine.
According to the screenshot of the system management there is already a Ui with -num 100 running and connected to both servers.
