Open Automation Software Tags can be defined to connect to Classic OPC Data Access 2.xx and 3.0 Servers with the built in OPC Interface. This tutorial walks you though downloading and installing OAS, configuring tags from your OPC Server, configuring alarm limits and configuring alarm notifications. Alarms notifications can be sent via e-mail, SMS text or voice to users based on specific filter criteria.
Step 1. Download and Install the Open Automation Software and Start the OAS Service
If you have not already done so, you will need to download and install the OAS platform. Fully functional trial versions of the software are available for Windows, Windows IoT Core, Linux, Raspberry Pi and Docker on our downloads page.
On Windows run the downloaded Setup.exe file to install one or more of the Open Automation Software features. Select the default Typical installation if you are not sure what features to use or the Custom installation if you want to save disk space on the target system. When prompted agree to the End User License Agreement to continue the installation.

The OAS Service Control application will appear when the installation finishes on Windows. Use this application to start the 3 Services. Run the Configure OAS application on Windows and select Configure-Tags; if the first time running, the AdminCreate utility will run to create an Administrator login as shown in Step 1 of Getting Started – Security.
