Cluster Connections Configuration

The Cluster Connections Setup page is used to specify the clusters that each component connects to on startup. This controls what data streams a component can see in the system.

The Cluster Connections Setup page lists each component's full name, including the cluster to which it belongs, the priorities of the components and the clusters assigned to each component. If the Multi-process option was not selected on the Computer Role Configuration page there will only be one entry listed, either Client or Client and Servers. If the Multi-process option was selected, you have the option of assigning clusters for each component on this computer.

By default, every component will connect to every cluster unless otherwise modified.

If the Clusters parameter value for a process is invalid, then the Citect SCADA Runtime will simply ignore it on startup.

1. Select the component from the list. To select multiple components, hold down the Ctrl key as you select each item.
2. Click Modify.
3. Select the clusters you want the component to connect to on startup.
4. Click OK.

When you complete the Setup Wizard, the clusters are written to each component section in the Citect.ini file; for example:

...
[Alarm.Cluster1.AlarmServer1]
CPU=1
Clusters=Sydney
...
[Trend.Cluster1.TrendServer1]
CPU=2
Clusters=Sydney,Tokyo
...
