CHAPTER 5: SETTINGS PRODUCT SETUPF60 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL 5-415The Distributed Network Protocol (DNP) allows for the optimization of control and data acquisition between the equipmentin the substation and the central control center. The protocol is scalable; that is, it is designed to be compatible with thelatest high speed LAN technology yet still be implemented over slower speed serial links.The DNP improves upon many master-slave protocols by improving overall communication performance requirementsand provides time-stamping with millisecond accuracy.The F60 supports the Distributed Network Protocol (DNP) version 3.0. DNP is enabled when the SETTINGS PRODUCT SETUP COMMUNICATIONS PROTOCOL setting is set to DNP 3.0. The F60 can be used as a DNP slave device connected tomultiple DNP masters (usually an RTU or a SCADA master station). Since the F60 maintains two sets of DNP data changebuffers and connection information, two DNP masters can actively communicate with the F60 at one time.See the UR Family Communications Guide for more information on DNP.The DNP Channels sub-menu is shown.SETTINGS PRODUCT SETUP COMMUNICATIONS DNP PROTOCOL DNP CHANNELSThe DNP CHANNEL 1 PORT and DNP CHANNEL 2 PORT settings select the communications port assigned to the DNP protocolfor each channel. Once DNP is assigned to a serial port, DNP is the only protocol running on that port; Modbus or IEC60870-5-103 are disabled. If DNP is assigned to RS485, the protocol must be set to DNP on the serial port configuration aswell, for the change to take effect. When the DNP CHANNEL 1(2) PORT setting is set to “Network - TCP,” the channel 1(2) DNPprotocol can be used over TCP/IP on the Ethernet ports. When this value is set to “Network - UDP,” the DNP protocol can beused over UDP/IP on channel 1 only.Changes to these port settings take effect when power has been cycled to the relay.The DNP ADDRESS setting is the DNP slave address. This number identifies the F60 on a DNP communications link. Assign aunique address to each DNP slave.The F60 can specify a maximum of five clients for its DNP connections. These are IP addresses for the controllers to whichthe F60 can connect. The settings follow.SETTINGS PRODUCT SETUP COMMUNICATIONS DNP PROTOCOL DNP NETWORK CLIENT ADDRESSES DNP OBJECT 23DEFAULT VARIATION: 1Range: 1, 2, 5, 6 DNP OBJECT 30DEFAULT VARIATION: 1Range: 1, 2, 3, 4, 5 DNP OBJECT 32DEFAULT VARIATION: 1Range: 1, 2, 3, 4, 5, 7 DNP NUMBER OF PAIREDCONTROL POINTS: 0Range: 0 to 32 in steps of 1 DNP TCP CONNECTIONTIMEOUT: 120 sRange: 10 to 7200 s in steps of 1 DNP EVENT TIME BASE:LOCALRange: UTC, LOCAL DNP CHANNELS DNP CHANNEL 1 PORT:NONERange: NONE, COM1 - RS485, COM2 - RS485, FRONTPANEL - RS232, NETWORK - TCP, NETWORK - UDP DNP CHANNEL 2 PORT:NONERange: NONE, COM1 - RS485, COM2 - RS485, FRONTPANEL - RS232, NETWORK - TCPDo not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation ofthose protocols.
