+##Product description
+In the sample project, data from a CODESYS controller is shared with other processes 
+by means of shared memory. The CODESYS package includes additional implementation examples 
+in C (Linux), C# (Windows), and C++ (Windows).
+
+##More information
+The CODESYS package includes the following examples:
+
+**SharedMemoryExampleExt.project**
+
+The project uses shared memory to read and write data with the ``SysShm`` library. 
+The ``DataExchange`` structure is used for data exchange. Values from shared memory 
+is read to the variable ``deInstRead``. The variable ``deInstWrite`` is used for 
+writing values to shared memory. The values of ``deInstWrite`` are changed in each cycle. 
+The values of both variables are displayed in the visualization. 
+
+The following examples read the value of ``deInstWrite`` and write to the variable ``deInstRead``:
+
+**SharedMemoryCLinux**
+
+C program for Linux to read and write data be means of shared memory
+
+**SharedMemoryWinCpp**
+
+C++ program for Windows to read and write data be means of shared memory
+
+**SharedMemoryWinCSharp**
+
+C# program for Windows to read and write data be means of shared memory
+
+**SharedMemoryExampleExt.project/SyncExample:**
+
+The application ``SyncExample`` shows how data can be read and written synchronously via shared memory.  
+
+**SynchronizationExample:**
+
+C++ program for Windows for synchronized reading and writing of data via shared memory. 
+In this example the data exchange is done by the application ``SyncExample``.
