hello all,
I have got a TCP/IP connection and I was using Wireshark to look how the connection works. Then I saw that the Modbus sends a query and a response what i was expecting but the after the response I see a ack message. First I thought it was from something else but if I send again a query and response it did it again
I allow find something on this website: http://modbus.control.com/thread/1236749105
This is exactly the same, but I do not really get the answers. Modbus is I guess always query and response. Why now query and response and a extra ack?
