    Section 2 1MRS240048-IB C DNP3 overview Section 2 DNP3 overview DNP3 standard The DNP3 protocol was developed by Westronic based on the early versions of the IEC 60870-5 standard telecontrol protocol specifications. Now the protocol specification is controlled by the DNP Users Group at www.dnp.org. The ISO/OSI based model supported by this protocol specifies physical, data link and application layers only.

    Section 2 1MRS240048-IB C DNP3 overview • Controlling all aspects of the physical layer. • In unsolicited reporting mode, performing collision avoidance/detection procedures to ensure reliable transfer of data across the physical link. • Responding to all valid frames received from the physical layer. Data link responsibilities: •...

  • Page 15: Application Layer Parameters

    Section 2 1MRS240048-IB C DNP3 overview 2.1.4 Application layer parameters When App layer confirm is disabled, the protection relay requests application confirmation for event messages only. When it is enabled, the protection relay also requests application confirmations for all the sent application. App confirm TO is the application layer confirmation timeout in milliseconds.

  • Page 17: Section 3 Vendor-Specific Implementation

    Section 3 1MRS240048-IB C Vendor-specific implementation Section 3 Vendor-specific implementation DNP3 link modes Serial and TCP/IP modes are available. They are mutually exclusive. 3.1.1 DNP3 data objects The DNP3 protocol in 615 series protection relays is built on top of the internal IEC 61850 data model.

  • Page 18: Dnp3 Tcp/Ip Mode

    Section 3 1MRS240048-IB C Vendor-specific implementation 3.1.3 DNP3 TCP/IP mode DNP3 TCP/IP link mode is supported by the protection relay. The protection relay listens for a connection from a DNP3 master on port 20000. A single DNP3 session can be run concurrently with IEC 61850, Modbus Serial and/or Modbus TCP.

  • Page 21 The Latch Off command sent to the even index point will be accepted but ignored [1] DNP3 Device Profile Document for ABB DPU2000R (DOCUMENT VERSION 1.10 MARCH 2005) [2] Network Mode Parameter 2 enables or disables Control Relay Output Block Paired Point operation. When enabled, this setting facilitates compatibility with earlier implementations of Paired Control Point operation in the device.

  • Page 22: Binary Output Status Points

    Section 3 1MRS240048-IB C Vendor-specific implementation (ABI). The control commands sent to the odd index points will work as the paired mode is disabled. For the complementary latch control points, the Momentary Relay (Pulse On), Trip and Latch On commands sent to the even index point will latch on that point, while the Close command sent to the even index point will latch on the next odd point (the even index +1 point).

  • Page 23: Analog Inputs

    Section 3 1MRS240048-IB C Vendor-specific implementation For example, a DNP3 control command may be blocked through hardware or software mechanisms; in this case, the actual status value would indicate the control failed because of the blocking. Looping CROB actual status values as BIs has several advantages. •...

    Section 3 1MRS240048-IB C Vendor-specific implementation DNP3 points 3.3.1 Point configuration The DNP3 point map is configurable in PCM600. All points in the protection relay may be remapped. In PCM600, the unmapped points in the variables list on the left may be inserted to the active point list on the right.

    Section 4 1MRS240048-IB C DNP3 parameters Section 4 DNP3 parameters Parameter descriptions Link parameters DNP physical layer configures DNP3 for the TCP/IP or serial channel. Unit address is the slave 16 bit link address. This value should be set between 1 and 65519, since DNP3 reserves the top 16 addresses.
  • Page 30 Section 4 1MRS240048-IB C DNP3 parameters Application layer parameters App layer confirm When disabled, the protection relay requests application confirmation to event messages only. When enabled, the protection relay also requests application confirmations to all application messages sent. App confirm TO is the application layer confirmation timeout in milliseconds. Application layer confirmations received from the master after App confirm TO has expired are not acknowledged by the protection relay.

When Legacy master UR is enabled, the protection relay does not send the initial unsolicited message. Unsolicited responses are sent without the need of the Enable Unsolicited command.
