Why is a modbus message so simple?
The structure of a Modbus message is kept extremely simple. The protocol's simplicity makes the performance of more complex tasks such as file transmission or logging time-consuming and complicated. One reason is that the Modbus only transmits simple byte streams, which have to be interpreted on the receiver side first.
