Networking Features

Provides the most robust, scalable, and reliable distributed networking platform for IIoT solutions


Never lose data on network or database engine failure. The OAS Data Historian buffers data in real time. If communications is lost to the destination database, or if the destination is unavailable for any reason, no data is lost. As soon as communications are reestablished, all data is transferred at high speed.

Supported Databases

Log data to one or more locations simultaneously, each with configurable parameters so data is targeted for each destination data store. Data can be logged to a wide variety of Database Engines as well as CSV files.

Data Visualization and Reporting

Open data can be accessed directly in user interface and other applications.
The OAS platform has the following additional components that can consume and visualize any open historical data.

Trend .NET 

Visualize real time and historical data in WPF and WinForm applications. Build customizable, interactive data explorers using Visual Studio, and any .NET language such as C# and VB.NET

Web Trend

Visualize real time and historical data in web and mobile applications. Deliver interactive web-based data interfaces with HTML, CSS, and Javascript in any web application environment


Automate the generation of reports and deliver them in multiple at custom intervals (e.g. hourly, daily, weekly, or monthly). Deliver reports as Word or Excel documents, PDFs, and HTML files or even sent directly to a networked printer


The data source can be local or remote without exposing your database. With OAS store and forward feature built in you will never lose records on an network failure. OAS implements edge computing with its Distributed Network Architecture to process and retain data at the source for up to 1 million data points per OAS Data Engine.
