Rules of Clustering

When configuring CitectSCADA the following clustering rules apply:

There are countless variations in how a clustered system can be configured. The most appropriate configuration will depend on the requirements for the solution to be deployed and the environment in which it is being deployed. For more information, refer to Typical system scenarios.

The diagram below is an example of a system running with two clusters across three machines. Every server and client component have been deployed in accordance with the clustering rules.

The next diagram demonstrates circumstances which do not correctly follow the clustering rules.

The CitectSCADA compiler or the CitectSCADA Runtime Manager detects when the rules of clustering are not being observed and advises the user accordingly.
