Introduction

The IEC 61158 fieldbus standard and its companion standards IEC 61784-1 and IEC 61784-2 define a set of communication protocols.

Implement distributed control of automated applications. Fieldbus technology is now generally accepted and proven to be viable. Therefore, many fieldbus technologies

The technology continues to improve, covering areas that have not been standardized, such as real-time, functional safety-related and information security-related applications.

This guidance technical document describes the principles of functional safety communication according to the IEC 61508 series of standards, and the specification is based on

Communication communication profiles and protocol layers of the IEC 61784-1, IEC 61784-2 and IEC 61158 series of standards (management and pairing)

Should be agreed upon), but does not include electrical safety and intrinsic safety aspects.

Figure 1 shows the relationship between this guidance document and the relevant safety and fieldbus standards in the mechanical environment.

Note. 6.7.6.4 (high complexity) and 6.7.8.1.6 (low complexity) in IEC 62061 specify the relationship between PL (category) and SIL.

The secure communication layer implemented according to the IEC 61508 series of standards as part of a safety-related system for safety-related systems

The transmission of messages (information) between two or more participants on the fieldbus provides the necessary credibility, or a fieldbus error or invalidation

The security behavior in the piece provides sufficient credibility.

The secure communication layer specified in this guidance document allows fieldbus to be used to require functional safety to achieve a safety integrity level

For the application of (SIL), the SIL rating is specified by its corresponding functional safety communication profile.

The final SIL statement for a system depends on the implementation of the functional safety communication profile selected within the system - in standard equipment

The implemented functional safety communication profile is not sufficient to prove that the device is a security device.

This guidance document describes.

--- Implement the basic principles of the IEC 61508 series of standards for safety-related data communication requirements, including possible transmission failures, remediation measures

Considerations that affect data integrity;

--- Functional safety communication profiles for multiple communication profiles in IEC 617841 and IEC 61784-2, including the IEC 61158 series

1 Scope

This guidance document specifies IEC 61784-1, IEC 61784-2 and IEC 61158 Type 18 and Type 23

CPF8's secure communication layer (services and protocols) and identifies the functional safety communication principles and guidelines defined in IEC 61784-3

The secure communication layer in the technical documentation is relevant.

Note 1. Does not include electrical safety and intrinsic safety aspects. Electrical safety involves dangers such as electric shock. Intrinsic safety involves potentially explosive environments

Danger.

This guidance document defines the transmission of security-related messages between participants in a distributed network using fieldbus technology.

Mechanism that meets the functional safety requirements of the IEC 61508 series of standards. These mechanisms can be used in a variety of industrial applications, such as process control

Manufacturing, manufacturing automation and machinery.

This guidance document provides guidance to developers and evaluators of equipment and systems that follow this guidance document.

Note 2. The final SIL statement of a system depends on the implementation of the functional safety communication profile selected in the system - in accordance with this guide in standard equipment

Sexual technical documentation to implement a functional safety communication profile is not sufficient to prove that the device is eligible for a secure device.
