+# PLC Chat Net Base Services
+ 
+ 
+## Product description
+ The sample project consists of a server application and a client application with a visualization for each.
+A client application communicates over the server application with another client application via TCP (Port 50000).
+The connection can be made either encrypted or unencrypted.

-This is the default page, edit it as you see fit. To add a new page simply reference it within brackets, e.g.: [SamplePage].
+### Establishing an unencrypted TCP connection

-The wiki uses [Markdown](/prj/codesys-example/plc-chat-nbs/home/markdown_syntax/) syntax.
+An unencrypted connection can be established by deactivating the 'Encrypted' switch.
+For the client and server application, the IP address of the server has to be specified in the 'IP Address' field.

-[[members limit=20]]
+### Establishing an encrypted TCP connection
+
+An encrypted connection can be established by activating the 'Encrypted' switch.
+In this case, the server has to have stored the client certificates as trusted certificates.
+The client applications each have to have stored the server certificate as trusted certificates.
+
+#### Configuration of the certificates
+
+- Open the 'PLC Shell' of the device (client and server)
+- Enter the following command: ``cert-genselfsigned``
+- Download and install the 'CODESYS Security Agent' tool from the CODESYS Store (see https://store.codesys.com/codesys-security-agent.html).
+- Open the 'Security Screen' view.
+- Select a specific certificate and save it to the PC.
+- Save the certificate of the client as trusted certificates of the server.
+- Save each certificate of the server as a trusted certificate of the client.
+- In the ``TCP_Client`` and ``TCP_Server`` programs, the ``info`` variable has to be set to the name (CN) of the specified certificate.
+
+The 'Go Online' button can be used to activate the server and establish a connection from the clients to the server.
+
