Topology

Topology comprises physical computers, clusters, server processes and I/O devices. SCADA functions such as an alarm-related event or an I/O operation run on the computers. In addition, these functions are combined into a logical entity known as a cluster and added as an alarm server or an I/O server process to computers for ease of administration.

Multiple functions from multiple clusters may run on a single machine; however, the resources available on the computer govern the feasibility of running these functions on that computer. Therefore, multiple clusters may be associated with a single computer or a single cluster may need to be configured across multiple computers.

You can configure the computers in your SCADA system and organize the processes in clusters in the Topology activity of Plant SCADA Studio. You can view, add and edit configuration information for computers, clusters, server processes and I/O devices.

The Topology activity can also be used to create and manage Profiles that can be used when deploying your project.

Note: If you created a project in a version of Plant SCADA prior to version 2016, you need to run the Migration Tool to view the project's system topology in Plant SCADA Studio.

Configuring a Topology

Configuring a topology involves the following steps:

1. Add Add a Computer and Add Network Addresses. Each physical computer in your system needs to be identified with a unique name and IP address.

2. Add Add a Cluster to create groups within your runtime components. Each cluster needs to be defined with a unique name.

3. Add the required server processes. Each process server needs to be named, and assigned to a cluster and network address.

   • Add an Alarm Server Process

   • Add a Report Server Process

   • Add a Trend Server Process

   • Add an I/O Server Process

   • Configure an OPC DA Server

4. Configure redundancy if it is required.

5. Add the I/O Devices in production your system.
