Revolution Pi Connect as Modbus TCP / MQTT Gateway

Hello,

I would like to convert Modbus TCP messages to MQTT messages adressed to a MQTT Broker.

There are multiple Modbus TCP Gateways, each with multiple Modbus TCP Slaves behind.

Would one Revolution Pi Connect solve that?

How many messages can the Revolution Pi Connect work with?

The Rate of incoming messages would be very fast, so i would need the Revolution Pi Connect for slow down the send rate too.


Dearly
Andy

Hi Andy, you have to go the way and instead of our Modbus stack you have to adapt the libModbusMaster yourself according to your needs.
Have a look at https://libmodbus.org/

Hi Dirk,

So, as i understand, the Hardware will still be the Revolution Pi Connect but i will use libModbusMaster Software on it?


Greetings
Andy

Hi Andy, exactly. You can disable the Modbus services i.e. in the WebStatus.
