    Section 2 1MAC306892-MB C IEC 60870-5 overview Section 2 IEC 60870-5 overview IEC 60870-5 protocol The companion standards IEC 60870-5-101 and IEC 60870-5-104 are derived from the IEC 60870-5 protocol standard definition. It specifies a functional profile for basic telecontrol tasks. The IEC 60870-5 protocol stack is based on the reduced reference model called enhanced performance architecture (EPA).

  • Page 16: Unbalanced Transmission

    Section 2 1MAC306892-MB C IEC 60870-5 overview 2.2.1 Unbalanced transmission When using unbalanced transmission, the controlling station controls the data traffic by polling the controlled outstations sequentially. In this case, the controlling station initiates all the message transfers while the controlled outstations can transmit only in response to the message from the controlling station.

  • Page 17: Event Acquisition

    Section 2 1MAC306892-MB C IEC 60870-5 overview 2.3.2 Event acquisition Events occur spontaneously at the controlled outstation's application level. The events are buffered in the controlled outstation because the events may appear faster than the communication link is able to transfer them. When unbalanced transmission is used on the link layer, the buffered events must be polled by the controlling station.

    Section 3 1MAC306892-MB C Vendor-specific implementation Section 3 Vendor-specific implementation 615/620 series implementation 3.1.1 Internal IEC 61850 data modeling The protective relay is natively using the IEC 61850 data model for data processing. In practice, some data which is not used by the system database might not be available. Furthermore, the data must be enabled in an IEC 61850 dataset to be able to be reported by IEC 60870-5-101/104.

    Section 3 1MAC306892-MB C Vendor-specific implementation 3.2.1 Configuring IEC 60870-5-101 To configure one protocol instance to work as IEC 60870-5-101 slave, configure the parameters to enable basic communication.  • Port According to the physical wiring, set either to "IEC101-COM1" or "IEC101- COM2".

  • Page 21: Troubleshooting

    Section 3 1MAC306892-MB C Vendor-specific implementation  • COT Length Should be set to 2. The standard requires COT Length set to 2 in both the master and the slave devices.  • IOA Length Usually, set to 3. This setting must have the same value in the master and slave devices.

    Section 3 1MAC306892-MB C Vendor-specific implementation Knowing that the missed data is not included in the interrogation list, the client can skip interrogation. If the addresses are configured to same (default), only one indication is sent regardless if the data is included in the interrogation or not. 3.3.3 Overflow situation clearing Overflow situation clearing is applicable only for the keep oldest events...

    Section 3 1MAC306892-MB C Vendor-specific implementation • Control operation is denied by the circuit breaker itself because of, for example, interlocking. • Remote Mode is not enabled. Addressing scheme 3.5.1 Default addresses There are some protection functions, which are not available in this protective relay, but might be available in other protective relays in the 615/620 series.

  • Page 24: End Delay

    Section 3 1MAC306892-MB C Vendor-specific implementation In the balanced mode, ClientIP is the address where the protective relay tries to connect when the communication is started. Once connected, the communication continues with that client. In the unbalanced mode, ClientIP defines the address from where the client's communication initiative is accepted.

  • Page 25: Link Mode

    Section 3 1MAC306892-MB C Vendor-specific implementation 3.6.6 Link mode • Unbalanced • Balanced (default) The settings defines the link mode. In the unbalanced mode, the protective relay listens for the client's commands and responds when needed. In the balanced mode, the protective relay opens the connection and sends a spontaneous report when something happens.

    Section 3 1MAC306892-MB C Vendor-specific implementation 3.6.10 ASDU address length • Min: 1 • Max: 2 • Default: 1 • Unit: bytes In some communication frames, the ASDU address is defined. The length of ASDU address element is configurable and should be set to the same value throughout the network.
