Product Overview
The OAS Universal Driver Interface SDK allows you to create communication drivers for the Open Automation Software IIoT Framework.
The SDK is free to use and you can develop as many IIoT drivers for OAS as you like from the example project provided.
Platform Components
The core of the OAS Platform, enabling data connectivity, server-to-server networking, and more
Log data in open format to MS SQL Server, Oracle, mySQL, PostgreSQL, Cassandra, MongoDB, SQLite, MariaDB, Access, SQL Azure, and CSV
Log events to open databases, and send notifications via SMS, email, and voicemail
Read and write data to Allen Bradley, Siemens, and Modbus devices, Universal Drivers, OPC, and OPC UA, open databases, and Excel
Connect to cloud-base IoT gateways such as AWS, Azure IoT, and MQTT Brokers
Develop custom Visualizations, User Interfaces, and Automation apps for Windows, web, native iOS and Android, integrate with .NET and REST APIs
Provides the most robust, scalable, and reliable distributed networking platform for IIoT solutions
Create Your Own Communication Drivers for OAS
You can create your driver with C# or Visual Basic .NET with the easy to follow Example Driver Interface code that installs with OAS.
View the Create Universal Driver Interface guide for easy to follow steps.
Define Your Interface Properties
Update the GetDefaultDriverConfig and GetDefaultTagConfig functions to define the Driver and Tag properties you would like included in OAS. Define data types, descriptions, and in-line help text that appear in the OAS configuration.
VB

DriverProps.Add(New ClassProperty("IPAddress", "IP Address", "IP Address of the controller.", GetType(String), "192.168.0.1", ClassProperty.ePropInputType.Manual)) |
C#

DriverProps.Add(new ClassProperty("IPAddress", "IP Address", "IP Address of the controller.", typeof(String), "192.168.0.1", ClassProperty.ePropInputType.Manual)); |
Implement Data Interface Methods
Update the Connect and Disconnect methods that are called when OAS starts and stops Runtime.
Update the AddTags method to receive user defined values for each configuration property you have defined for continuous monitoring.

Public Overrides Sub AddTags(ByVal Tags() As List(Of ClassProperty)) Try 'Add Logic. Props is a list of ClassProperty in the same order of Get Tag Config Dim Props As List(Of ClassProperty) For Each Props In Tags ' Use the TagName as a unique identifier for the Tag Name and Paramater being interfaced with. Dim TagID As String = GetPropValue(Props, "TagName") ' Use the polling rate to set the communication rate to your device or software application. ' If you interface uses async callbacks with a subscription rate you could create multiple collections of tags based on PollingRate. Dim PollingRate As Double = GetPropValue(Props, "PollingRate") Next Catch ex As Exception RaiseEvent UpdateSystemError(True, "Communications", 1, "AddTags Exception: " + ex.Message) End Try End Sub |

public override void AddTags(List<ClassProperty>[] Tags) { try { foreach (List<ClassProperty> Props in Tags) { // Use the TagName as a unique identifier for the Tag Name and Paramater being interfaced with. string TagID = Convert.ToString(GetPropValue(Props, "TagName")); // Use the polling rate to set the communication rate to your device or software application. // If you interface uses async callbacks with a subscription rate you could create multiple collections of tags based on PollingRate. double PollingRate = Convert.ToDouble(GetPropValue(Props, "PollingRate")); } } catch (Exception ex) { if (UpdateSystemError != null) UpdateSystemError(true, "Communications", 1, "AddTags Exception: " + ex.Message); } } |
Post value changes in your own code routines using the AsyncReadCallback event.

localArrayList.Add(New ClassTagValue(TagID, Value, currentTime, Quality)) ... RaiseEvent AsyncReadCallback(CType(localArrayList.ToArray(GetType(ClassTagValue)), ClassTagValue())) |

localArrayList.Add(new ClassTagValue(TagID, Value, currentTime, Quality)); ... if (AsyncReadCallback != null) AsyncReadCallback((ClassTagValue[])localArrayList.ToArray(typeof(ClassTagValue))); |
Include quality and timestamp information for resolution up to 100 nanaseconds.
Additionally update the WriteValues method to process writes from OAS Tags.
Data Available to All OAS Features
Send and receive data to any OAS data source or destination.
Host your own data over the Internet.
Log data to SQL Server, Oracle, Access, mySQL, MariaDB, PostgreSQL, SQLite, MongoDB, Cassandra, and CSV files.
Send alarm notifications via text, email, or voice.
