The IEC 61850 protocol is an IEC standard designed for communication with Intelligent Electronic Devices (

IED) at electrical substations (breakers, protections, transformers, switches, etc).

The IEC 61850 protocol is - like IEC 60870-6 ICCP/TASE.2 - based on the Manufacturing Message Specification (MMS) and therefore the implementation in the D2000 KOM process uses a common MMS framework.

Implementation of the IEC 61850 protocol in the D2000 system supports this functionality:

1. Periodic reading of values (polling)

2. Reading of values from predefined Datasets made available in predefined Information Reports - both buffered and unbuffered

3. Reading of array elements which are simple values

4. Writing to simple types of values (writing to structures is not implemented yet)

5. Writing to array elements of which are simple values

6. Writing - control according to the "Select Before Operate With Enhanced Security" model

7. Browsing - when communication is established, the following items can be browsed:

• • logical devices within a physical device (in the station address configuration)

  • objects located within the logical device (in the I/O tag configuration)

  • reports located within the logical device (in the I/O tag configuration)

There is no support for the processing of GOOSE and GSSE reports.

The ISO over TCP/IP transmission layer is implemented according to the RFC 1006 specification.

The protocol was tested with:

• software simulators

• ABB Substation management unit COM600

• ABB Feeder protection and control REF615

• communication adapter ABB SPA-ZC 400

Note for ABB SPA-ZC 400: when adding objects to the dataset (in Communication Enginering Tool for SPA-ZC40x), it is necessary to check the option "Export Datasets DO Level" so that the entire object (e.g. Pos) is added as one structured variable (otherwise, its components are added as independent report items, e.g. Pos$stVal, Pos$q, Pos$t).

• Communication line category: TCP/IP-TCP.

• TCP Parameters:

  • Host: string max. 80 characters – server name in INET format (a name or numerical address a.b.c.d) 

  • Port: TCP port number (0 to 65535), port 102 is used by default.

  • Line number: not used, set to 1

A valid hostname or IP address of the device must be entered according to the rules above.

The port number where the device is listening must also be entered. The ISO over TCP/IP standard uses port 102.

In the case of redundant systems, it is also possible to enter multiple comma-separated names/addresses. When the connection is broken, the communication process will again attempt to establish a connection to the device at the specified address. If the attempt is unsuccessful, then the process tries to establish a connection to the next address. This is repeated cyclically until the connection with one server is established.
