+# OPC Foundation UA .NET Standard Library - Console Reference Publisher
+
+## Introduction
+This OPC application was created to provide the sample code for creating Publisher applications using the OPC Foundation UA .NET Standard PubSub Library. There is a .NET Core 3.1 (2.1) console version of the Publisher which runs on any OS supporting [.NET Standard](https://docs.microsoft.com/en-us/dotnet/articles/standard).
+The Reference Publisher is configured to run in parallel with the [Console Reference Subscriber](../ConsoleReferenceSubscriber/README.md)
+
+## How to build and run the console OPC UA Reference Publisher from Visual Studio
+1. Open the solution **UA Reference.sln** with Visual Studio 2019.
+2. Choose the project `ConsoleReferencePublisher` in the Solution Explorer and set it with a right click as `Startup Project`.
+3. Hit `F5` to build and execute the sample.
+
+## How to build and run the console OPC UA Reference Publisher on Windows, Linux and iOS
+This section describes how to run the **ConsoleReferencePublisher**.
+
+Please follow instructions in this [article](https://aka.ms/dotnetcoregs) to setup the dotnet command line environment for your platform. 
+
+## Start the Publisher
+1. Open a command prompt.
+2. Navigate to the folder **Applications/ConsoleReferencePublisher**.
+3. To run the Publisher sample execute: 
+
+`dotnet run --project ConsoleReferencePublisher.csproj --framework netcoreapp3.1` 
+
+
+The Publisher will start and publish network messages that can be consumed by the Reference Subscriber. 
+Publisher Initialization
+
+## Command Line Arguments for *ConsoleReferencePublisher*
+ **ConsoleReferencePublisher** can be executed using the following command line arguments:
+ 
+
+ -  -h|help - Shows usage information
+ -  -m|mqtt_json - Creates a connection using there MQTT with Json encoding Profile. This is the default option.
+ -  -u|udp_uadp - Creates a connection using there UDP with UADP encoding Profile. 
+
+To run the Publisher sample using a connection with MQTT with Json encoding execute: 
+
+		dotnet run --project ConsoleReferencePublisher.csproj --framework netcoreapp3.1 
+
+		or 
+
+		dotnet run --project ConsoleReferencePublisher.csproj --framework netcoreapp3.1 -m
+
+To run the Publisher sample using a connection with the UDP with UADP encoding execute: 
+
+		dotnet run --project ConsoleReferencePublisher.csproj --framework netcoreapp3.1 -u
+
+# Programmer's Guide
+To create a new OPC UA Publisher application:
+
+ - Open Microsoft Visual Studio 2019 environment,
+ - Create a new project and give it a name,
+ - Add a reference to the [OPCFoundation.NetStandard.Opc.Ua.PubSub NuGet package](https://www.nuget.org/packages/OPCFoundation.NetStandard.Opc.Ua.PubSub/),
+ - Initialize Publisher application (see [Publisher Initialization](#publisher-initialization)).
+
+## Publisher Initialization
+
+The following four steps are required to implement a functional Publisher:
+
+ 1. Create [Publisher Configuration](#publisher-configuration).
+ 
+		// Create configuration using MQTT protocol and JSON Encoding
+        PubSubConfigurationDataType pubSubConfiguration = CreatePublisherConfiguration_MqttJson();
+    
+      Or use the alternative configuration object for UDP with UADP encoding
+	  
+		// Create configuration using UDP protocol and UADP Encoding 
+        PubSubConfigurationDataType pubSubConfiguration = CreatePublisherConfiguration_UdpUadp();      
+        
+	The CreatePublisherConfiguration methods can be found in  [ConsoleReferencePublisher/Program.cs](./Program.cs) file.
+
+ 2. Create an instance of the [UaPubSubApplication Class](../../Docs/PubSub.md#uapubsubapplication-class) using the configuration data from step 1.
+ 
+        // Create an instance of UaPubSubApplication
+        UaPubSubApplication uaPubSubApplication = UaPubSubApplication.Create(pubSubConfiguration);
+
+ 3. Provide the data to be published based on the configuration of published data sets. This step is described in the [Publisher Data](#publisher-data) section.
+ 4. Start PubSub application
+
+        // Start the publisher
+        uaPubSubApplication.Start();
+
+After this step the Publisher will publish data as configured.
+
+## Publisher Configuration
+
+The Publisher configuration is a subset of the [PubSub Configuration](../../Docs/PubSub.md#pubsub-configuration). A functional *Publisher* application needs to have a configuration (*PubSubConfgurationDataType* instance) that contains a list of published data sets (*PublishedDataSetDataType* instances) and at least one connection (*PubSubConnectionDataType* instance) with at least one writer group configuration (*WriterGroupDataType* instance). The writer group contains at least one data set writer (*DataSetWriterDataType* instance) pointing to a published data set from the current configuration.
+
+The diagram shows the subset of classes involved in an *OPC UA Publisher* configuration.
+
+![PublisherConfigClasses](../../Docs/Images/PublisherConfigClasses.png)
+
+## Publisher Data
+
+The [UaPubSubApplication Class](../../Docs/PubSub.md#uapubsubapplication-class) provides a property of type [IUaPubSubDataStore](../../Docs/PubSub.md#iuapubsubdatastore-interface) called DataStore. In **ConsoleReferencePublisher** there is no custom implementation provided for *IUaPubSubDataStore* therefore the pub sub application object is initialized using the default implementation of this interface, an instance of *UaPubSubDataStore*. 
+
+The code responsible for generating the data values to be published is located in the [PublishedValuesWrites](/PublishedValuesWrites.cs)  file from the **ConsoleReferencePublisher** project. It maintains a list of all the fields from the table below and uses a timer for writing the values to *UaPubSubApplication.DataStore* using the *WritePublishedDataItem*() method from *DataStore* class. The data values simulator component is initialized like:
+
+    // Start values simulator
+    PublishedValuesWrites valuesSimulator = new PublishedValuesWrites(uaPubSubApplication);
+    valuesSimulator.Start();
+
+The **Publisher** component from **ConsoleReferencePublisher** application will use the data generated by *PublishedValuesWrites* to create the *NetworkMessages* that will be published as configured in [Publisher Configuration](#publisher-configuration).
+
+Note:  
+The current PubSub implementation only supports *PublishedDataItemsDataType* as *DataSetSource* of a *PublishedDataSetDataType* from the configuration. *Events* will be added in a future version.
+
+The **ConsoleReferencePublisher** application is configured to use the following data sets and will generate values as specified in the table below if the default configuration method is used:
+
+### PublishedDataSet 'Simple' - NamespaceIndex = 2
+| Name  | DataType  |  ValueRank |Behavior  |
+|--|--|--|--|
+|BoolToggle |Boolean |Scalar |Toggles every 3 seconds|
+|Int32|Int32|Scalar |Counts (1 per second) from 0 to 10,000 and then resets|
+|Int32Fast|Int32Fast|Scalar |Counts (100 per second) from 0 to 10,000 and then resets|
+|DateTime|DateTime|Scalar |Current time refreshed with every packet sent|
+
+The *CreatePublishedDataSetSimple*() method from [Program.cs](Program.cs) creates a *PublishedDataSetDataType* configuration object that contains the metadata information for *'Simple' DataSet*.
+
+### PublishedDataSet 'AllTypes' - NamespaceIndex = 3
+| Name  | DataType  |  ValueRank |Behavior  |
+|--|--|--|--|
+|BoolToggle |Boolean |Scalar |Toggles every second|
+|Byte|Byte|Scalar |Counts (1 per second) from 0 to type-max and then resets|
+|Int16|Int16|Scalar |Counts (1 per second) from 0 to type-max and then resets|
+|Int32|Int32|Scalar |Counts (1 per second) from 0 to type-max and then resets|
+|SByte|SByte|Scalar |Counts (1 per second) from 0 to type-max and then resets|
+|UInt16|UInt16|Scalar |Counts (1 per second) from 0 to type-max and then resets|
+|UInt32|UInt32|Scalar |Counts (1 per second) from 0 to type-max and then resets|
+|UInt64|UInt64|Scalar |Counts (1 per second) from 0 to type-max and then resets|
+|Float|Float|Scalar |Counts (1 per second) from 0 to type-max and then resets|
+|Double|Double|Scalar |Counts (1 per second) from 0 to type-max and then resets|
+|String|String|Scalar |Spells the aviation alphabet (Alpha, Bravo …) (1 per second)|
+|ByteString|ByteString|Scalar |1 new random ByteString per second|
+|Guid|Guid|Scalar |1 new random Guid per second|
+|DateTime|DateTime|Scalar |Current time refreshed with every packet sent|
+|UInt32Array|UInt32|OneDimension|Counts (1 per second on every element) from 0 to type-max and then resets. The count starting point for each value should differ|
+
+The *CreatePublishedDataSetAllTypes*() method from [Program.cs](Program.cs) creates a *PublishedDataSetDataType* configuration object that contains the metadata information for *'AllTypes' DataSet*.

+# OPC Foundation UA .NET Standard Library - Console Reference Subscriber
+
+## Introduction
+This OPC application was created to provide the sample code for creating Subscriber applications using the OPC Foundation UA .NET Standard PubSub Library. There is a .NET Core 3.1 (2.1) console version of the Subscriber which runs on any OS supporting [.NET Standard](https://docs.microsoft.com/en-us/dotnet/articles/standard).
+The Reference Subscriber is configured to run in parallel with the [Console Reference Publisher](../ConsoleReferencePublisher/README.md)
+
+## How to build and run the Windows OPC UA Reference Server from Visual Studio
+1. Open the solution **UA Reference.sln** with Visual Studio 2019.
+2. Choose the project `ConsoleReferenceSubscriber` in the Solution Explorer and set it with a right click as `Startup Project`.
+3. Hit `F5` to build and execute the sample.
+
+## How to build and run the console OPC UA Reference Subscriber on Windows, Linux and iOS
+This section describes how to run the **ConsoleReferenceSubscriber**.
+
+Please follow instructions in this [article](https://aka.ms/dotnetcoregs) to setup the dotnet command line environment for your platform. 
+
+## Start the Subscriber
+1. Open a command prompt.
+2. Navigate to the folder **Applications/ConsoleReferenceSubscriber**.
+3. To run the Subscriber sample type 
+
+`dotnet run --project ConsoleReferenceSubscriber.csproj --framework netcoreapp3.1.` 
+
+The Subscriber will start and listen for network messages sent by the Reference Publisher. 
+
+## Command Line Arguments for *ConsoleReferenceSubscriber*
+ **ConsoleReferenceSubscriber** can be executed using the following command line arguments:
+ 
+
+ -  -h|help - Shows usage information
+ -  -m|mqtt_json - Creates a connection using there MQTT with Json encoding Profile. This is the default option.
+ -  -u|udp_uadp - Creates a connection using there UDP with UADP encoding Profile. 
+
+To run the Subscriber sample using a connection with MQTT with Json encoding execute: 
+
+		dotnet run --project ConsoleReferenceSubscriber.csproj --framework netcoreapp3.1 
+
+		or 
+
+		dotnet run --project ConsoleReferenceSubscriber.csproj --framework netcoreapp3.1 -m
+
+To run the Subscriber sample using a connection with the UDP with UADP encoding execute: 
+
+		dotnet run --project ConsoleReferenceSubscriber.csproj --framework netcoreapp3.1 -u
+
+# Programmer's Guide
+To create a new OPC UA Subscriber application:
+
+ - Open Microsoft Visual Studio 2019 environment,
+ - Create a new project and give it a name,
+ - Add a reference to the [OPCFoundation.NetStandard.Opc.Ua.PubSub NuGet package](https://www.nuget.org/packages/OPCFoundation.NetStandard.Opc.Ua.PubSub/),
+ - Initialize Subscriber application (see [Subscriber Initialization](#subscriber-initialization)).
+
+## Subscriber Initialization
+
+The following four steps are required to implement a functional Subscriber:
+
+ 1. Create [Subscriber Configuration](#subscriber-configuration).
+ 
+        // Create configuration using UDP protocol and UADP Encoding 
+        PubSubConfigurationDataType pubSubConfiguration = CreateSubscriberConfiguration_UdpUadp();
+    
+      Or use the alternative configuration object for MQTT with JSON encoding
+                
+        // Create configuration using MQTT protocol and JSON Encoding
+        PubSubConfigurationDataType pubSubConfiguration = CreateSubscriberConfiguration_MqttJson();
+
+    The CreateSubscriberConfiguration methods can be found in  [ConsoleReferenceSubscriber/Program.cs](./Program.cs) file.
+
+ 2. Create an instance of the [UaPubSubApplication Class](../../Docs/PubSub.md#uapubsubapplication-class) using the configuration data from step 1.
+ 
+        // Subscribe to data events 
+        UaPubSubApplication uaPubSubApplication = UaPubSubApplication.Create(pubSubConfiguration);
+
+ 3. Provide the event handler for the *DataReceived* 	event. This event will be raised when data sets matching the subscriber configuration arrive over the network. See the DataReceived Event section for more details.
+
+        // Create an instance of UaPubSubApplication
+        uaPubSubApplication.DataReceived += PubSubApplication_DataReceived;
+
+ 4. Start PubSub application
+
+        // Start the publisher
+        uaPubSubApplication.Start();
+
+After this step the *Subscriber* will listen for *NetworkMessages* as configured.
+## Subscriber Configuration
+
+The Subscriber configuration is a subset of the [PubSub Configuration](../../Docs/PubSub.md#pubsub-configuration). A functional *Subscriber* application needs to have a configuration (*PubSubConfgurationDataType* instance) that contains at least one connection (*PubSubConnectionDataType* instance) with at least one reader group configuration (*ReaderGroupDataType* instance). The reader group contains at least one data set reader (*DataSetReaderDataType* instance) that describes a published data set that can be processed and retrieved by the *Subscriber* application.
+The diagram shows the subset of classes involved in an *OPC UA Publisher* configuration.
