Example: Using the Web Socket Client SL Library
Product: CODESYS IIOT Libraries SL
The Web Socket SL Example.project sample project shows how to use of the Web Socket Client SL library. The sample project contains a visualization to establish a bidirectional connection to a web server via the Internet. Communication usually takes place via the TCP port number 443 for secured connections or 80 for unsecured connections.
Note
Parsing and generating messages based on the subprotocol is not implemented in the WebSocket client and has to be done by the layer above (example: MQTT client).
