Centralizing Data from Multiple Sources into One OPC Server

What is data aggregation?

Data aggregation is the bringing together of data from different OPC servers (and other data sources) into a single data source, so that one or more OPC clients (or other clients) can access this data through a single common interface.

Depending on what solution you choose, data aggregation is about more than just OPC - it's about centralized collection of data from all of your various data source to create a comprehensive data set for your entire enterprise.

What are some key benefits of data aggregation?

• Reduce load on clients by making all of your data available through a single connection.
• Accessing data through a single client connection can also save you money if your client application requires a license for each server connection.
• Collect data from all of your various data sources and present it to the user as a shared common data set.
• Client programs never need to know which program originated the data in order to read and write to it since there is a common place to access it.

Built-in data aggregation using TOP Server

TOP Server has multiple options for aggregating data from a variety of data sources beyond just connecting to and polling data from PLCs, RTUs and other process devices.

TOP Server has drivers capable of aggregating data from the following other data sources:

• OPC UA servers
• OPC DA servers
• OPC XML-DA servers
• DDE servers
• ODBC databases
• AVEVA InTouch (formerly Wonderware)
• MQTT brokers
