Detailed Description

Dummy client.

Dummy client provides implementation of fake Modbus master (client) that connects to imaginary Modbus slave (server). Contrary to real client it can be forced to write to memory regions specified by Modbus protocol as read-only (discrete inputs and input registers). This class is useful when prototyping and testing behavior of client application as it can also emulate latency and it does not require running Modbus slave (server) to work with.
