This document specifies requirements for the exchange of messages that contain master data consisting of characteristic data. These requirements can be checked by computer. The messages are suitable for exchange between organizations and between systems. EXAMPLE 1    A supplier sends a message to a customer. The message contains characteristic data describing an item that the customer is considering buying. The following are within the scope of this document: —   conformance of master data messages to a formal syntax; —   semantic encoding of master data messages; —   conformance of master data messages to data specifications; —   requirements on access to the data dictionaries that enable decoding of master data messages. The following are outside the scope of this document: —   master data that are not characteristic data; —   data that are not in messages; —   messages that do not exchange master data between organizations or systems; EXAMPLE 2    A merchant sends a message to a credit card company. The message represents a credit charge transaction and does not exchange master data between the organizations. —   recording the provenance of master data; EXAMPLE 3    ISO 8000‑120 addresses the capture and exchange of data provenance information. —   accuracy of master data; EXAMPLE 4    ISO 8000‑130 addresses the representation and exchange of information about the accuracy of master data that consists of characteristic data. —   exchange of data that are not master data; EXAMPLE 5    ISO 8000‑140 addresses the representation and exchange of information about the completeness of master data that consists of characteristic data. —   management of master data internally within an organization; EXAMPLE 6    Data within an organization's enterprise resource planning or product data management system is out of scope. EXAMPLE 7    Making backup copies of data files containing master data is out of scope. —   quality of data dictionaries; —   a specific formal syntax for the exchange of master data. EXAMPLE 8    The ISO 9735 series, the ISO 13584 series, the ISO 15926 series and the ISO 22745 series specify formats that enable exchange of master data. The requirements in this document are considered necessary but not sufficient to achieve data quality with respect to exchange of master data. Issues such as the accuracy and provenance of master data also need to be addressed as part of an overall data quality strategy.

This International Standard specifies requirements and makes recommendations for the design,
integration and validation of safety-related control systems (SCS) for machines. It is applicable
to control systems used, either singly or in combination, to carry out safety functions on
machines that are not portable by hand while working, including a group of machines working
together in a co-ordinated manner.
This document is a machinery sector specific standard within the framework of IEC 61508 (all
parts).
The design of complex programmable electronic subsystems or subsystem elements is not
within the scope of this document. This is in the scope of IEC 61508 or standards linked to it;
see Figure 1.
NOTE 1 Elements such as systems on chip or microcontroller boards are considered complex programmable
electronic subsystems.
The main body of this sector standard specifies general requirements for the design, and
verification of a safety-related control system intended to be used in high/continuous demand
mode.
This document:
– is concerned only with functional safety requirements intended to reduce the risk of
hazardous situations;
– is restricted to risks arising directly from the hazards of the machine itself or from a group
of machines working together in a co-ordinated manner;
NOTE 2 Requirements to mitigate risks arising from other hazards are provided in relevant sector standards.
For example, where a machine(s) is part of a process activity, additional information is available in IEC 61511.
This document does not cover
– electrical hazards arising from the electrical control equipment itself (e.g. electric shock –
see IEC 60204-1);
– other safety requirements necessary at the machine level such as safeguarding;
– specific measures for security aspects – see IEC TR 63074.
This document is not intended to limit or inhibit technological advancement.

This part of the IEC 61784-3 series explains some common principles that can be used in the
transmission of safety-relevant messages among participants within a distributed network
which use fieldbus technology in accordance with the requirements of IEC 61508 (all parts) 1
for functional safety. These principles are based on the black channel approach. They can be
used in various industrial applications such as process control, manufacturing automation and
machinery.
This part and the IEC 61784-3-x parts specify several functional safety communication
profiles based on the communication profiles and protocol layers of the fieldbus technologies
in IEC 61784-1, IEC 61784-2 and IEC 61158 (all parts). These functional safety
communication profiles use the black channel approach, as defined in IEC 61508. These
functional safety communication profiles are intended for implementation in safety devices
exclusively.
NOTE 1 Other safety-related communication systems meeting the requirements of IEC 61508 (all parts) can exist
that are not included in IEC 61784-3 (all parts).
NOTE 2 It does not cover electrical safety and intrinsic safety aspects. Electrical safety relates to hazards such
as electrical shock. Intrinsic safety relates to hazards associated with potentially explosive atmospheres.
All systems are exposed to unauthorized access at some point of their life cycle. Additional
measures need to be considered in any safety-related application to protect fieldbus systems
against unauthorized access. IEC 62443 (all parts) will address many of these issues; the
relationship with IEC 62443 (all parts) is detailed in a dedicated subclause of this document.
NOTE 3 Implementation of a functional safety communication profile according to this document in a device is not
sufficient to qualify it as a safety device, as defined in IEC 61508 (all parts).
NOTE 4 The resulting SIL claim of a system depends on the implementation of the selected functional safety
communication profile within this system.
NOTE 5 Annex C explains the numbering scheme used for the technology-specific parts (IEC 61784-3-x) as well
as their common general structure.
NOTE 6 Annex D provides a guideline for the assessment and test of safety communication profiles as well as
safety-related devices using these profiles.

This part of IEC 62769 defines the FDI Information Model. One of the main tasks of the
Information Model is to reflect the topology of the automation system. Therefore, it represents
the devices of the automation system as well as the connecting communication networks
including their properties, relationships, and the operations that can be performed on them.
The types in the AddressSpace of the FDI Server constitute a catalogue, which is built from
FDI Packages.
The fundamental types for the FDI Information Model are well defined in OPC UA for Devices
(IEC 62541-100). The FDI Information Model specifies extensions for a few special cases and
otherwise explains how these types are used and how the contents are built from elements of
DevicePackages.
