VDI/VDE 2183

Reliable operation of Ethernet-based bus systems in industrial automation

active, Most Current
Organization: VDI
Publication Date: 1 January 2018
Status: active
Page Count: 71
ICS Code (Microprocessor systems): 35.160
ICS Code (IT applications in industry): 35.240.50
scope:

This standard enables planners and operators of Ethernet-based communication networks in industrial applications, as the persons responsible for installation, and service engineers to take consideration of all the measures required for reliable operation of this type of communication system. The standard's structure is based on the lifecycle model:

a) requirements

b) planning

c) installation

d) commissioning

e) operation

Hence, persons applying this standard are given advice and support in all phases of setting up and operating the network. Furthermore, the standard provides an overview of all relevant standards and additional sources of information. The standard supports the user in all the named aspects. This standard does not address specific application protocols, but focusses on Ethernets according to IEEE 802.3 and switching according to IEEE 802.1, or the bridge functions of Real-time Ethernet versions according to IEC 61158-3 and IEC 61158-4, as well as on the redundancy functions according to DIN EN 62439.

Note: In this standard, the terms "switch" and "bridge" are used interchangeably. They are used for MAC-Bridges within the meaning of IEEE 802.1 or the bridge functionality of Realtime Ethernet versions according to IEC 61158-3 and IEC 61158-4. Terms such as "layer 2" or "layer 3" usually refer to the OSI model according to ISO/IEC 7498-1.

Important remark 1

All components which have no direct function in the network, e.g. sensors, actuators, etc. are not included in the discussions concerning the system's reliability.

Important remark 2

In a conventional LAN environment, e.g. in an office, the network components are only exposed to moderate temperatures and mechanical stress, whereas network components used in industrial environments often have to withstand a higher temperature range and are exposed to other special ambient conditions (e.g. mechanical stress, electromagnetic radiation). The real-time and availability requirements, which have to be met owing to proximity to the physical processes, are characteristic for automation technology. Hence, even a brief network failure can have a negative impact on production processes and therefore has to be avoided as far as possible, depending on the area of application.
