Select the CONFIGURATION column and check that the Comms settings cell is set to Visible.2. Select the COMMUNICATIONS column.3. Move to the first cell down (RP1 protocol). This is a non-settable cell, which shows the chosencommunication protocol – in this case DNP3.0.COMMUNICATIONSRP1 ProtocolDNP3.04. Move down to the next cell (RP1 Address). This cell controls the DNP3.0 address of the IED. Up to 32 IEDs canbe connected to one spur, therefore it is necessary for each IED to have a unique address so that messagesfrom the master control station are accepted by only one IED. DNP3.0 uses a decimal number between 1and 65519 for the Relay Address. It is important that no two IEDs have the same address.COMMUNICATIONSRP1 Address15. Move down to the next cell (RP1 Baud Rate). This cell controls the baud rate to be used. Six baud rates aresupported by the IED 1200 bps, 2400 bps, 4800 bps, 9600 bps, 19200 bps and 38400 bps. Make sure thatthe baud rate selected on the IED is the same as that set on the master station.P14x Chapter 18 - CommunicationsP14xEd1-TM-EN-1 429
