    5. Modbus Applications The WF-2000 is a Modbus device that allows you to access terminals data via Wi-Fi and communicates using a master-slave technique in which only one device (the master) can initiate transactions (called queries). The other devices (slaves) respond by supplying the requested data to the master, or by taking the action requested in the query.

    For example a client can read the ON/OFF states of a group of digital input or output or it can read/write the data contents of a group of registers. When the server responds to the client, it uses the function code field to indicate either a normal response or that some kind of error occurred (called an exception response).
