    Section 2 1MRS756709 D 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.
  • Page 14 Section 2 1MRS756709 D DNP3 overview Data link responsibilities: • Exchange of SDUs between peer DNP3 data links • Error notification to data link user • Sequencing of SDUs • SDU delivery quality. Link-layer confirm usage is deprecated. See the DNP technical bulletin TB1998-0402, section 3 for details at www.dnp.org.

    Section 2 1MRS756709 D DNP3 overview In the present implementation, the binary output object may not be assigned to generate events in classes 1, 2 or 3. Instead, the outputs are available as binary inputs, which may then be assigned to generate events. The actual status of the binary outputs can be read from the binary inputs.

    Section 3 1MRS756709 D Vendor-specific implementation Section 3 Vendor-specific implementation DNP3 link modes 3.1.1 DNP3 data objects The DNP3 protocol in 615 series IEDs is built on top of the internal IEC 61850 data model. Thus, the DNP3 application data objects and Class events are derived from IEC 61850 data objects and data set reporting.

    Section 3 1MRS756709 D Vendor-specific implementation Table 5: CROB fields supported Point index Name/description Supported CROB fields See the point list manual. 1) In this IED implementation the pulse-on time cannot be commanded from the DNP3 master. A value in the variable pulse-on time field in the CROB command is ignored, but the command is accepted. It should be noticed that control pulse lengths for CB controls in this IED are configurable via PCM600.

    Section 3 1MRS756709 D Vendor-specific implementation 3.3.3 Accessing non-protocol mapped data Since the 615 series version 4.0.0, the IED application includes a number of general purpose I/O data. By default, these data are mapped to this protocol. See the point list manual for the exact mappings. The general purpose objects can be connected to any internal object in the IED configuration application by ACT or SMT tool.

    Section 4 1MRS756709 D 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 26 Section 4 1MRS756709 D DNP3 parameters 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 IED. App layer fragment is the application layer fragment size in bytes. Unsolicited mode parameters UR mode Unsolicited responses mode may be set to enable or disable.
  • Page 27 Section 4 1MRS756709 D DNP3 parameters Legacy master UR allows non-standards compliant behavior. Legacy master SBO provides compatibility to some older DNP3 masters for the Select Before Operate command. When disabled, DNP3 expects the application layer sequence of the operate command to be the select command sequence + 1 modulo 16.

  • Page 28: Parameter List

    Section 4 1MRS756709 D DNP3 parameters Deadbanding of the analog static values cannot be set in DNP3. Event generation is dependent on the functions employed in the IED, and the execution loops these functions belong to. See the IED’s technical manual for setting deadbands. As a result of the event generation mechanism in the IED, the events reported by DNP3 are very accurate and are the same events that can be retrieved over the WHMI or other protocols such as IEC 61850-8-1.
