IEC 60870-5-101/104 protocol implementation

RER620 39

Point List Manual

Section 3 IEC 60870-5-101/104 protocol

implementation

This section describes the specific implementation of the IEC 60870-5-101 protocol

within the RER620. The RER620 uses the Triangle MicroWorks, Inc. IEC 60870-5-101

Slave Source Code Library Version 3.

This section and the documents listed below provide complete information on how to

communicate with a RER620 via the IEC 60870-5-101 protocol.

• IEC 60870-5-101 = Companion standard for basic telecontrol tasks

• IEC 60870-5-5 = Basic Application Functions

• IEC 60870-5-2 = Link Transmission Procedures

• IEC 60870-5-4 = Definition and Coding of Application Information Elements

• IEC 60870-5-3 = General Structure of Application Data

• IEC 60870-5-1 = Transmission Frame Formats

Please note that the IEC60870-5-104 protocol support shares application level feature of

the 101 implementation defined in this section.

The pages in this section have been extracted from the 60870-5-101 © IEC:2003, Section

8. The section numbers below have been purposely retained from that document for

8 Interoperability

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 octets 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 command and in monitor direction 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 stemming from different manufacturers

it is necessary that all partners agree on the selected parameters.

The selected parameters should be marked in the white boxes as follows:

Function or ASDU is not used

Function or ASDU is used as standardized (default)

Function or ASDU is used in reverse mode

Function or ASDU is used in standard and reverse mode
