      Hi!
      I've already implement the master TCP to read some energy meters, but the function 17 i'm not getting to do.
      Here is its rules:
      Request: (slaveId , function number, crc)
      (1, 17, CRC)

       Response: 15 bytes
               slaveId: 1
               func. Num.: 17
               count byte: 10
               float IEEE32BITS: 64 | 0 | 4 | 234
               serial number: 0 | 18 | 214 | 135
               meter type: 0 | 188
               CRC
      
         How can i do this?
      

      I tried this way, but not work ...

      
      ModbusRequest mr = new ReadInputRegistersRequest(1, 17, 1);
      ReadInputRegistersResponse rep = (ReadInputRegistersResponse) master.send(mr);
      
      

      att
