Station communication Line differential protection RED670 1MRK505228-BEN E

　　Each IED is provided with a communication interface, enabling it to connect to one or many substation level systems or equipment, either on the Substation Automation (SA) bus or Substation Monitoring (SM) bus.

　　Following communication protocols are available:

　　• IEC 61850-8-1 communication protocol

　　• LON communication protocol

　　• SPA or IEC 60870-5-103 communication protocol

　　• DNP3.0 communication protocol

　　Theoretically, several protocols can be combined in the same IED.

　　IEC 61850-8-1 communication protocol

　　The IED is equipped with single or double optical Ethernet rear ports (order dependent) for IEC 61850-8-1 station bus communication. The IEC 61850-8-1 communication is also possible from the optical Ethernet front port. IEC 61850-8-1 protocol allows intelligent electrical devices (IEDs) from different vendors to exchange information and simplifies system engineering. Peer-to-peer communication according to GOOSE is part of the standard. Disturbance files uploading is provided.

　　Serial communication, LON

　　Existing stations with ABB station bus LON can be extended with use of the optical LON interface. This allows full SA functionality including peer-to-peer messaging and cooperation between existing ABB IED's and the new IED 670.

　　SPA communication protocol

　　A single glass or plastic port is provided for the ABB SPA protocol. This allows extensions of simple substation automation systems but the main use is for Substation Monitoring Systems SMS.

　　IEC 60870-5-103 communication protocol

　　A single glass or plastic port is provided for the IEC60870-5-103 standard. This allows design of simple substation automation systems including equipment from different vendors. Disturbance files uploading is provided.

　　DNP3.0 communication protocol

　　An electrical RS485 and an optical Ethernet port is available for the DNP3.0 communication. DNP3.0 Level 2 communication with unsolicited events, time synchronizing and disturbance reporting is provided for communication to RTUs, Gateways or HMI systems.

　　Multiple command and transmit

　　When 670 IED's are used in Substation Automation systems with LON, SPA or IEC60870-5-103 communication protocols the Event and Multiple Command function blocks are used as the communication interface for vertical communication to station HMI and gateway and as interface for horizontal peerto-peer communication (over LON only).

　　IEC 62439-3 Parallel Redundant Protocol

　　Redundant station bus communication according to IEC 62439-3 Edition 1 and IEC 62439-3 Edition 2 are available as options in 670 series IEDs. IEC 62439-3 parallel redundant protocol is an optional quantity and the selection is made at ordering. Redundant station bus communication according to IEC 62439-3 uses both port AB and port CD on the OEM module.

　　Select IEC 62439-3 Edition 1 protocol at the time of ordering when an existing redundant station bus DuoDriver installation is extended. Select IEC 62439-3 Edition 2 protocol at the time of ordering for new installations with redundant station bus. IEC 62439-3 Edition 1 is NOT compatible with IEC 62439-3 Edition 2.
