( 6 ) Function Code (PARAM04)
Set a function code to transmit.
The functions (read coil or input relay state, write to holding register, etc.) registered in the function codes are made
available by specifying the code.
The following table shows the function codes available when using a MEMOBUS or Extended MEMOBUS protocol.
Note: 1. B: Bit type, W: Integer type
2. : Available, –: Not available
3. Transmit and receive registers in the master operation mode are MW (MB) only.
4. In slave operation mode, the coil, holding register, input relay, and input register are MB, MW, IB, IW
