178 Practical Modern SCADA Protocols: DNP3, 60870.5 and Related Systems is not really independent of IEC 60870-5-101, but replaces the message transport sections with a network version, leaving the application level functions largely unaltered. Main Parts Reference Description Year IEC 60870-1 General Considerations 1988 IEC 60870-2 Operating Conditions 1995 IEC 60870-3 Interfaces (electrical characteristics) 1989 IEC 60870-4 Performance Requirements 1990 IEC 60870-5 Transmission Protocols 1990 IEC 60870-6 Telecontrol Protocols Compatible 1995 with ISO and ITU-T Recommendations Sections of IEC 60870-5 Reference Description Year IEC 60870-5-1 Transmission Frame Formats 1990 IEC 60870-5-2 Link Transmission Procedures 1992 IEC 60870-5-3 General Structure of Application Data 1992 IEC 60870-5-4 Definition and Coding of Application 1993 Information Elements IEC 60870-5-5 Basic Application Functions 1995 Companion Standards of IEC 60870-5 Reference Description Year IEC 60870-5-101 Companion Standard for Basic Telecontrol Tasks 1995 IEC 60870-5-102 Companion Standard for Transmission of Integrated Totals 1996 IEC 60870-5-103 Companion Standard for Protection Communication 1997 IEC 60870-5-104 Network Access using Standard Transport Profiles 2000 Table 8.1 Full structure of IEC 60870 standard
Fundamentals of IEC 60870-5 179 8.1.2 Development of standards IEC standards are subject to review and the issue of amendments from time to time, and since the publication of IEC 60870-5-101, this profile has had two amendments issued. The first amendment added a small number of information object definitions. The second amendment added a significant amount of clarifying detail, the purpose of which was to remove ambiguities and so better provide for interoperability. It is anticipated that during 2002 the standard will be reissued as one document including the two amendments. With amendments the complete version of this profile is as shown in Table 8.2. Reference Description Year-Month IEC 60870-5-101 Companion Standard for Basic Telecontrol Tasks 1995-11 IEC 60870-5-101-am1 Companion Standard for Basic Telecontrol Tasks Amendment 1 2000-04 IEC 60870-5-101-am2 Companion Standard for Basic Telecontrol Tasks Amendment 2 2001-10 Table 8.2 IEC 60870-5-101 including amendments 8.1.3 Obtaining standards Should access to the standards be required, they may be purchased online from the IEC (at www.iec.ch). As an alternative that may be less expensive, it is worth checking if they have been published as a national standard, as is often the case. In Australia, IEC 60870-5 sections 1 to 5 are available as AS 60870.5.1 to AS 60870.5.5 and are available online (at www.standards.com.au). However, the companion standards are not presently available and must be obtained from the IEC. An alternative to purchase of the standards is to view them at a public or university library. 8.1.4 Description of contents In this section the contents of each section of IEC 60870-5 are briefly described. This is intended to provide a guide to assist the reader should it be necessary to refer to them. IEC 60870-5-1 1990 Transmission frame formats This describes the operation of the physical and data link layers in terms of the services provided to higher layers. It provides a choice of four data link frame types identified as FT1.1, FT1.2, FT2 and FT3, each with a different level of security against data errors. Fixed and variable length versions of the frames are described, and a set of transmission rules is provided for each. Two single control character transmissions are provided as an efficient means of transmitting control information such as acknowledgments.
