        Modbus TCP flexible input triggered read node with connection input parameters.
    </p>
    <p>Connects to a Modbus TCP or serial to read coils/inputs/registers at the rate of the incoming msg.</p>
    <p>
        <h4>Function codes (1:4) currently supported include:</h4>

        <ul>
          <li>FC 1: Read Coil Status</li>
          <li>FC 2: Read Input Status</li>
          <li>FC 3: Read Holding Registers</li>
          <li>FC 4: Read Input Registers</li>
        </ul>
        </p>
     <p>
         <strong>Input parameter for connecting Modbus</strong>
         <ul>
             <li>unitid (0..255 tcp | 1..247 serial) - overrides default Unit-ID</li>
             <li>fc (1..4)</li>
             <li>start address (0:65535)</li>
             <li>quantity (1:65535) of coils/inputs/registers to be read from the start address</li>
         </ul>
     </p>

     <p>Output 1: data Array (PDU), modbus response Buffer, input message</p>
     <p>Output 2: modbus response Buffer, data Array (PDU), input message</p>

     <p>Function node code example for single input:</p>
     <code>
        msg.payload = { value: msg.payload, 'fc': 1, 'unitid': 1, 'address': 0 , 'quantity': 1 }
        return msg
     </code>

     <p>Function node code example for multiple inputs:</p>
     <code>
        msg.payload = { value: msg.payload, 'fc': 3, 'unitid': 1, 'address': 0 , 'quantity': 10 }
        return msg
     </code>
