Data collected from Modbus TCP. And maybe exist some optimal method for thats type of communication? Thank you for helps. Hello, again as I've sugested, count +/- amount of data you want exchange. Why select Modbus TCP? Did you think/check what you need for Modbus TCP? I think yiou need licences for both modules but you need check this. Again, more other solutions exists but depends to amount of data. Your thoughts? You don't need create new topic, we can probably continue here... Update: I think PUT/GET can be simplest solution for you...
