I am working in a project with two servers and two clients.
The servers will work in Redundancy mode, but I am having trouble with that.
I'm using the software WinCC 7.2 + Upd7.
On the servers I'm using Windows Server 2008 R2 Standard, and the clients I'm using Windows 7 Pro.
I follow the configuration on the WinCC Redundancy manual:
- Inserted the Server/Client/Redundancy Licenses in respectively machines;
- Change the Project Type to 'Multi-User Project';
- Add the clients computer to the project;
- Set the Time Synchronization;
- Activate the Redundancy, set the Partner Server/Connection to partner and select the optional settings (Alarm Logging syncs and the client switch);
- Created a Server Data (Appears the name of the Physical and Redundant computers);
- Create the Alarms for Redundancy.
I make a copy of the project to the Redundant Partner Server with the Project Duplicator tool.
I start the Runtime on the Master Server, waited until its loaded.
Then I started the runtime on clients computer, waited until they are loaded.
Then I started the runtime on the Redundant Server and waited until its loaded.
After all the servers and clients was in Runtime, I follow the Alarm log messages and noticed that the Master computer recognized that the partner project was activated (Message 1012226), then about 10 minutes later, the Archive synchronization started (Message 1012208), then about 2 minutes later it finishes (Message 1012209).
After these messages, I waited about 1 hour, using the project, and no more messages about Redundancy or Sync was generated.
I observed the Redundancy tags and they are not with the correct values, they were like:
Code: Select all
'@RedundantServerState' = 4
'@RM_MASTER' = 0
'@RM_MASTER_NAME' = (null)
'@RM_OFFLINE_UA_NAME' = 0.0
'@RM_SERVER_NAME' = {The local machine name}I've already setted the network card speed to not automatic.
Both servers are identical, with hardware, software and the project.
I don't know what is wrong and why the redundancy is not working.
Does anybody can help me with this configuration?
