BS EN 60870 is a series on telecontrol equipment and systems. Telecontrol equipment and systems an electronic devices used to operate another device from a distance, usually wirelessly. BS EN 60870-6-601 defines the provision of the OSI Connection-mode Transport Service between an End System (“The Reference End System”) which uses a Permanent Analog or Digital Circuit to access a Packet Switched Data Network (PSDN) and another End System (“The Compatible End System”) which is accessible, by permanent or switched methods, either directly from the same Packet Switched Data Network, or indirectly through the provided OSI Connection-mode Network Service.
BS EN 60870-6-601 also defines the provision of the OSI Connection-mode Network Service between the Reference End System and the Compatible End System using the X.25 subnetwork procedures to a Packet Switched Data Network. BS EN 60870-6-601 is applicable to environments that support the OSI Network Service. In the ISO taxonomy four options are defined as a function of the transport protocol classes operated:
Group TB: includes transport protocol classes 0, 2 and 4
Group TC: includes transport protocol classes 0 and 2
Group TD: includes transport protocol class 0
Group TE: includes transport protocol class 2
Who is BS EN 60870-6-601 - Packet Switched Data Network for?
BS EN 60870-6-601 on Packet Switched Data Network is useful for:
Telecommunication component manufacturers
Telecommunication equipment manufacturers
Design engineers
Quality control personnel
Why should you use BS EN 60870-6-601 - Packet Switched Data Network?
Telecontrol equipment and systems function best when used from a short distance. BS EN 60870-6-601 defines functional profiles to be used in telecommunication networks for electric power systems. It is largely based on existing ISO/IEC International Standards and International Standardized Profiles (ISP). The notion of Functional Profile is fundamental in the organization of IEC 870-6. A description of Functional Profiles, their classification scheme, and the manner of defining them are laid down in BS EN 60870-6-601. BS EN 60870-6-601 is a Transport-class Profile providing the Connection-mode Transport Service (COTS) over the Connection-mode Network Service (CONS) for the specific case of permanent access to a Packet Switched Data Network. Implementation of the option TD (class 0 only) requires that the End System does not operate any of the multiplexing classes (class 2, 3, or 4) of the Transport Protocol procedures. Such End Systems will only interwork with End Systems that also implement Class 0 Transport Protocol procedures. Implementation of the other options (groups TB, TC, TE) in one End System, enables that End System to interwork with any End System conforming to ISO 8073.
BS EN 60870-6-601 recommends the implementation of classes 0, 2 and 4 in End Systems. In the ISO taxonomy, such End Systems with permanent access to a PSDN are referenced with profiles TB1111 (for analogue access) or TB1121 (for digital access). The format of BS EN 60870-6-601 is in conjunction with one of the ISO/IEC ISPs. These ISPs are defined in a multi-part way. For example, to define the profiles TB1111 and TB1121, the present section refers to the three different ISO/IEC ISPs, listed in BS EN 60870-6-601. When applicable the present section follows ISO/IEC ISP 10609-1, ISO/IEC ISP 10609-5, and ISO/IEC ISP 10609-9. BS EN 60870-6-601 defines some complementary specifications to ISP 10609. Those specifications mainly concern priority management and the transport class negotiation. Using BS EN 60870-6-601 you can define the provision of the OSI Connection-mode Transport Service between an End System (“The Reference End System”) which uses a Permanent Analog or Digital Circuit to access a Packet Switched Data Network and another End System.
