Overview

In addition to data collection from monitoring devices, PME can also connect to and share data with other systems or software. Using PME in such a connected way is called system integration.

In an integrated system, PME either acts as a server, providing data to other systems, or as a client, receiving data from other systems, or both at the same time. Real-time data and historical data can be exchanged between the systems.

The reason for integrating systems is to leverage the strengths and capabilities of each system in order to provide value that could not be achieved with any of the systems alone.

 

PME offers the following technologies for system integration:

• OPC server for exporting real-time data.
• OPC client for importing real-time data.
• EWS server for exporting real-time data, historical data, and alarm data.
• EWS client for importing historical data and alarm data.
• ETL for exporting or importing historical data.
• ODBC for providing access to historical data.
• PQDIF for exporting power quality data.
• VIP for exporting or importing real-time data or historical data.

 

Each of these technologies has its strengths and weaknesses. Which technologies to use depends on the system capabilities, the application needs, and the performance expectations. See Integration technologies for more details.
