Large network

This topology configuration includes dedicated nodes running Application Object Servers, while visualization tasks are performed on separate nodes.

The benefits of this topology include usability, flexibility, scalability, system reliability, and ease of system maintenance, since all configuration data resides on dedicated servers.

The client components (represented by the visualization nodes) provide the means to operate the process using applications that provide data updates to process graphics. The clients have a very light data processing load.

The ApplicationObject Server nodes share the load of data processing, alarm management, communication to external devices, security management, etc.

The following figure illustrates a client/server topology:

This topology is scalable to include a greater number of servers. Including more servers distributes data processing loads and enables a higher load of I/O reads/writes. Client nodes can be added when additional operator stations are needed.
