3 CONFIGURING THE DATA PROTOCOLSDifferent protocols can be used with the various ports. The choice of protocol depends on the chosen model.Only one data protocol can be configured at any one time on any one IED. The range of availablecommunication settings depend on which protocol has been chosen.Depending on the exact model, the following choices may be available:● Courier● Tunneled Courier over Ethernet● MODBUS● DNP3● DNP3 Over Ethernet● IEC 60870-5-103● IEC61850Note:Not all protocols are available on all productsYou can configure the settings using the settings application software or the HMI. This section describes howto configure the device using the HMI.3.1 COURIER CONFIGURATIONTo configure the device:1. 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 Courier.COMMUNICATIONSRP1 ProtocolCourier4. Move down to the next cell (RP1 Address). This cell controls the address of the IED. Up to 32 IEDscan be connected to one spur. It is therefore necessary for each IED to have a unique address so thatmessages from the master control station are accepted by one IED only. Courier uses an integernumber between 1 and 254 for the Relay Address. It is set to 255 by default, which has to bechanged. It is important that no two IEDs share the same address.COMMUNICATIONSRP1 Address100Chapter 4 - Configuration MiCOM P74768 P747-TM-EN-1
