  • Safety Guidelines This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are graded according to the degree of danger.

    DANGER indicates that death or severe personal injury will result if proper precautions are not taken.

    WARNING indicates that death or severe personal injury may result if proper precautions are not taken.

    CAUTION with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.

    CAUTION without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.

    NOTICE indicates that an unintended result or situation can occur if the corresponding information is not taken into account.

    If more than one degree of danger is present, the warning notice representing the highest degree of danger will be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property damage.

    Qualified Personnel The device/system may only be set up and used in conjunction with this documentation. Commissioning and operation of a device/system may only be performed by qualified personnel. Within the context of the safety notes in this documentation qualified persons are defined as persons who are authorized to commission, ground and label devices, systems and circuits in accordance with established safety practices and standards.

    Preface

    Target group and motivation The networking manual accompanies you through all phases of preparation and implementation of network projects. It provides you with an overview of the structure and configuration of Industrial Ethernet networks with the aid of SIMATIC NET. On the one hand, the target groups are decision makers and planners; with this documentation, they can gain an overview of the technical principles, the SIMATIC NET product range and the most important practical applications. On the other hand, it provides configuration engineers and commissioning personnel with extensive information and reference data to which they can refer when setting up their network systems.

    Structure of the document The networking manual consists of three parts, structured as follows:

  • Preface

    Industrial Ethernet Networking Manual 4 System Manual, 06, 6GK1970-1BA10-0AA0

    Table 1 Structure of the Networking Manual

    Part Content and target group Part A: Basics Chapters 1 and 2

    This part is intended for decision makers and planners. The basics of network communication technology, the special features of Industrial Ethernet and the essential characteristics of SIMATIC NET products are presented in a readily understandable form. Particular emphasis is placed on the SCALANCE generation of devices. This part closes with a chapter introducing the most common network topologies and practical applications along with the components required for them. The chapter is not only instructive; you can also use it as a practical starting point for planning your own systems.

    Part B: Product overview Chapters 3 to 5

    The second part is also intended for decision makers and planners. This part introduces the entire product ranges of SIMATIC NET. Here, you will find the main characteristics of the SCALANCE generation of switches, security and wireless components - the emphasis being on their technical properties. OSM and ESM devices, passive components (such as cables and connectors) and accessories are also described.

    Part C: Technical specifications and reference Chapters 6 to 12

    The last part is intended for configuration engineers and commissioning personnel. You will find extensive reference data as required in the planning and commissioning of a system. The document contains dimension drawings, specifications, certifications and much more helpful information on SIMATIC NET components that will support you when setting up an actual plant or network.

    Topics such as product properties or supported network topologies are therefore described more than once at various points in this book. The various aspects that are in the foreground for the reader at a particular point are then highlighted.

    Operating Instructions and other documents Despite every effort being made to provide a complete and thorough picture, the Industrial Ethernet Networking Manual cannot replace the Operating Instructions and reference documents of the individual devices and components. You will find the detailed documentation of the individual components on the Manual Collection DVD.
