?Should I always use TLS with MQTT?

!Yes, you should if you can. If you can afford the overhead in CPU and bandwidth, then a secure communication channel is invaluable. Depending on the general CPU performance it could be possible to have a noticeable reduction of communication performance.

?Is it possible to have multiple connections?

!Yes, you can connect the Analytics Logger at the same time to different Message Broker just by adding a new instance of the Logger. Also it is possible to have one instance of the Logger for an MQTT communication to a Message Broker and at the same time one instance for writing data into Analytics File to the local system.

Is it possible to control the Analytics Logger by a PLC function block?

!Yes, it is possible to control the Logger with the Analytics Communication Library. Details and examples can be found on the Overview page in the API chapter.

I still have a 4024 system and would like to use the Logger. How do I install it?

!The drivers and the configuration interface for the Analytics Logger are already available in every 4024 XAE and XAR system. Nothing needs to be installed additionally. Only the configuration needs to be carried out and activated on the target system.
