TF6760 | 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. REST APIs can be used, for example, to query weather data, to communicate with messenger services or as an interface for writing to a database.

The TF6760 TwinCAT 3 IoT HTTPS/REST function provides 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. Message contents can be defined, interpreted and used for communication directly from the PLC context via XML and JSON parsers.
