TwinCAT 3 IoT HTTPS/REST

So-called REST (Representational State Transfer) APIs are frequently offered by web servers in IoT communication in order to channel certain communication processes via a uniform and stateless interface. Although REST is basically independent of the transport system, the Internet of Things mainly uses the HTTP/HTTPS protocol established in web communication as, among other things, it enables better compatibility with firewalls. There are many different application scenarios for connecting an HTTP/REST interface from within the controller, ranging from the simple determination of weather data through to complex communication processes.

The TwinCAT 3 Function TF6760 TC3 IoT HTTPS/REST provides users with basic functions for HTTP/HTTPS communication in a PLC library enabling them to address REST APIs as a client and providing HTTP commands such as GET, PUT and POST. The communication channel (HTTPS) is secured by SSL/TLS mechanisms, which are also provided. Message contents can be defined, interpreted and used for communication directly from the PLC context via XML and JSON parsers.
