Introduction

This topic contains the information that is used to configure devices from other providers for interoperability. It is based on the standard IEC60870-5-101 interoperability template (IEC60870-5-101:2003, Clause 8).

This companion standard presents sets of parameters and alternatives from which subsets have to be selected to implement particular telecontrol systems. Certain parameter values, such as the number of bytes in the common address of ASDUs, represent mutually exclusive alternatives. This means that only one value of the defined parameters is admitted per system. Other parameters, such as the listed set of different process information in the command and monitor directions, allow the specification of the complete set or subsets, as appropriate for given applications. This clause summarizes the parameters of the previous clauses to facilitate a suitable selection for a specific application. If a system is composed of equipment from different manufacturers, it is necessary that all partners agree on the selected parameters.

The selected parameters should be marked in the white boxes:

The function or ASDU is not used.

The function or ASDU is used as standardized (default).

The function or ASDU is used in reverse mode.

The function or ASDU is used in standard and reverse mode.

The possible selection (empty, X, R, or B) is specified for each specific clause or parameter.

NOTE: In addition, the full specification of a system may require individual selection of certain parameters for certain parts of the system, such as the individual selection of scaling factors for individually addressable measured values.

System or Device

System-specific parameters indicate the definition of a system or a device by marking these boxes with an X:

system definition

Link Layer

For network-specific parameters, all implemented options are marked with an X. Specify the maximum frame length. If a non-standard assignment of class 2 messages is implemented for unbalanced transmission, indicate the type ID and COT of all messages assigned to class 2.

Frame format FT 1.2, single character 1, and the fixed timeout interval are used exclusively in this companion standard.

Link Transmission Procedure

Address Field of the Link

balanced transmission

unbalanced transmission

Frame Length

maximum length L (control direction)

maximum length L (monitor direction)

When using an unbalanced link layer, these ASDU types are returned in class 2 messages (low priority) with the indicated causes of transmission (X).

This is the standard assignment of ASDUs to class 2 messages:

Type Identification

Cause of Transmissions

9, 11, 13, 21

<1>
This is the special assignment of ASDUs to class 2 messages:

Type Identification

1, 3, 5, 7, 9, 11, 13 <2>
NOTE: In response to a class 2 poll, a controlled station may respond with class 1 data when there is no class 2 data available.

Application Layer

Transmission mode for application data

Mode 1 (least significant byte first), as defined in 4.10 of IEC60870-5-4, is used exclusively in this companion standard.

For system-specific parameters, all implemented configurations are marked with an X:

one byte

two bytes

unstructured

Cause of transmission

For system-specific parameters, all implemented configurations are marked with an X:

NOTE: The originator address is set to 0 if not used.
