Hi Armin,
thank you for your answer.
Here some more Information about my project. Now I’m using the NetPi as a “translator”, it receives MQTT messages and translate it to Profinet. I’m working on a communication to both sides (from MQTT to Profinet and from Profinet to MQTT).
In the next step, I want to implement a data logger on the NetPi. I want to save the messages on a hard disk, I prefer SSD. I would like to use one of the NetPi’s USB Slots to connect it with the SSD. The highest consuming Power is 3 Watt, maybe less.
In the easiest case, the messages get a time stamp and are saved on the hard disk. But there is lot of traffic on the bus, so it would be better (when it is possible) to use a database.
In the best case, it is possible to get data from the database over Profinet or Ethernet. I have no idea if that is possible. But if you have a good idea for me, I’m very thankful.
Best wishes,
Jan
