Beckhoff: TF6020 – TC3 JSON Data Interface
October 28, 2020
The TC3 JSON Data Interface is an interface for the exchange of data in JSON format between the TwinCAT system and custom applications. The JSON format enables access with different programming languages to the ADS interface. It is possible to access all symbols of the runtime that are also available with the standard ADS interface.
Communication between the TwinCAT system and the custom applications can be realised in different ways. An integrated MQTT client in the TwinCAT system enables the communication with MQTT brokers. The MQTT broker is configured in the TwinCAT system and supports TLS encryption.
