Developer SDKs and APIs

Build Automation apps using Developer Tools and APIs for .NET, web technologies, native iOS and Android mobile apps, and using a REST API for devices and applications on any platform. Developers can create automated configurations and deployments of OAS-based systems, and even custom device or protocol drivers for integration with proprietary systems using the Universal Driver Interface SDK.

Product Overview

The OAS Platform includes a wide variety of Developer Tools and APIs to allow you to create applications and system integrations to execute in any environment.

.NET Developers have access to assemblies for creating data integrations and automations. The .NET Core Components to allow .NET developers to even create native iOS and Android apps using Xamarin.

Developers not using .NET can easily create cross-platform applications using the OAS REST API for real time and historical data read/write as well as automated OAS Platform server configuration.

The OAS SDKs and APIs allow system integrators to build applications which roll out new OAS installations, saving thousands of man-hours.

Platform Components

Universal Data Connector

The core of the OAS Platform, enabling data connectivity, server-to-server networking, and more

Data Historian

Log data in open format to MS SQL Server, Oracle, mySQL, PostgreSQL, InfluxDB, MongoDB, SQLite, MariaDB, Access, SQL Azure, Amazon Aurora, Amazon RDS, Amazon Redshift, Google Firebase, and CSV files

Alarm Logging & Notification

Log events to open databases, and send notifications via SMS, email, and voicemail

Device & Data Connectors

Read and write data to Allen Bradley, Siemens, and Modbus devices, Universal Drivers, OPC, OPC UA, databases, Excel, and read MTConnect.

IoT Connectors

Connect to cloud-base IoT gateways such as AWS, Azure IoT Hub, Azure Event Hubs, Kafka, MQTT, and Sparkplug B

Visualization Tools

Build custom Visualizations, User Interfaces, HMIs and Dashboards for Windows, web, as well as native iOS and Android devices


Develop custom automation apps for Windows, web, and mobile devices. Integrate with .NET and REST APIs. Build custom integrated device drivers.

Networking Features

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

Developer Tools

One of the most powerful features of the OAS Platform is automation. Using our components and APIs, the OAS Universal Data Connector configuration itself can be automated. This allows for the creation of applications that can build and manage OAS tag configurations and more. And of course, all tag data can be processed in real time through these interfaces, opening a world of data integrations to developers.

.NET Data Connector

Create custom integrations, headless data feeds, or even automate the configuration of an OAS service. Using the .NET Data Connector any C# or VB.NET application can take advantage of the OAS service.

.NET Core for iOS and Android

Native mobile applications for iOS and Android can be built using the OAS .NET Core Components and Xamarin. Apps can be deployed to the Apple App Store for iOS or Google Play Store for Android.

Universal Driver Interface

Create your own communication drivers using C# or VB.NET and define custom interface and tag properties. This SDK is easy to use and deploy and free of charge to develop unlimited numbers of drivers.


Any application code capable of executing HTTP calls can communicate with an OAS service to read and write tag data, as well as read trend and alarm data. OAS server configurations can also be managed through the API.
