MQTT functions

The MQTT blocks are standard →functions for transferring unencrypted data between PLCs.

These blocks are provided in the sub-folder MQTT of the system library System. The sub-folder is provided in projects that have been created by using a project template.
Do not manipulate the folder and its contents! If you do nevertheless, logi.CAD 3 does not find the library or the blocks any longer.

logi.CAD 3 supports the following MQTT blocks:

• MQTT_Connect block

• MQTT_Disconnect block

• MQTT_GetState block

• MQTT_Publish block

• MQTT_Receive block

• MQTT_Subscribe block

• MQTT_Unsubscribe block

The data is transferred by means of an already existing MQTT broker

(see "Preparing/Realizing data transfer via MQTT")
