This European Standard applies to controller device interfaces that provide defined interfaces between low voltage switchgear, controlgear, control circuit devices, switching elements and controlling devices (e.g. programmable controllers, personal computers, etc.). It may also be applied for the interfacing of other devices and elements to a controller device interface. This standard specifies requirements for controllers and devices utilising these interfaces, including not only the communication protocol specification, but also associated relevant electrical and mechanical characteristics. It also specifies the electrical and EMC tests required to verify the performance of each controller device interface when connected to the appropriate controllers and devices. This part 1 establishes a consistent terminology and format for the subsequent interfaces. It also harmonises requirements of a general nature in order to reduce the need for testing to different standards, increase understanding and facilitate comparisons of controller device interface standards. Those requirements of the various controller device interface standards which can be considered as general have therefore been gathered in this part 1. In addition to meeting the specific requirements stated in this part 1, the controller device interfaces included in this standard  are documented in the English language in accordance with the requirements specified in this part 1,  are already in use in commercial products and running in industrial plants,  are available in quantity and at low price,  are available from several sources and commercialised openly,  to satisfy the tests specified, amongst others, in EN 61000 4 2, EN 61000 4 3, EN 61000 4 4, EN 61000 4 5, and EN 61000 4 6 against the test levels specified in EN 50082 2,  have appropriate mechanisms for transmission error detection,  are open, widely accepted, well documented, stable and support inter operability,  are complete and describe the necessary interfaces in sufficient detail to enable error free implementation,  are free of any restriction related to testing the implementation. For each controller device interface only two documents are necessary to determine all requirements and tests:  the general requirements of this standard, referred to as "part 1" in the relevant parts covering the various types of controller device interfaces;  the relevant controller device interface standard hereinafter referred to as the "relevant controller device interface standard" or "controller device interface standard". The solutions described in this standard have been used for many years by industry to solve application requirements involving low voltage switchgear and controlgear. They are characterised by:  their ability to power connected devices directly from the network;  their ability to operate in harsh environments typified by those encountered at the machine level by controls in industrial applications;  usage of the sophisticated medium access rules of CAN which allows both organisation of traffic based on user assigned priorities and efficient resolution of occasional access conflict;  a wide range of exchange services allowing precise tailoring of data exchange to the actual application needs as well as simultaneous distribution of data to a selected set of connected devices;  their capability to simultaneously support data acquisition, diagnostics, messaging and programming/configuration as required, amongst others, for systems interfacing controllers to low voltage switchgear and controlgear in industrial applications. NOTE The controller device interface standards currently part of this series are:  EN 50325 2: DeviceNet  EN 50325 3: Smart Distributed System (SDS)  EN 50325-4: CANopen  EN 50325-5 : Functional safety communication based on EN 50325-4

This part of the IEC 62443 series provides detailed technical control system requirements (SRs) associated with the seven foundational requirements (FRs) described in IEC 62443‑1‑1 including defining the requirements for control system capability security levels, SL-C(control system). These requirements would be used by various members of the industrial automation and control system (IACS) community along with the defined zones and conduits for the system under consideration (SuC) while developing the appropriate control system target SL, SL-T(control system), for a specific asset.
As defined in IEC 62443‑1‑1 there are a total of seven FRs:
a) Identification and authentication control (IAC),
b) Use control (UC),
c) System integrity (SI),
d) Data confidentiality (DC),
e) Restricted data flow (RDF),
f) Timely response to events (TRE), and
g) Resource availability (RA).
These seven requirements are the foundation for control system capability SLs, SL-C (control system). Defining security capability at the control system level is the goal and objective of this standard as opposed to target SLs, SL-T, or achieved SLs, SL-A, which are out of scope.
See IEC 62443‑2‑1 for an equivalent set of non-technical, program-related, capability SRs necessary for fully achieving a control system target SL.

IEC 61158-6-2:2019 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 2 fieldbus. The term “time-critical” is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of certainty. Failure to complete specified actions within the time window risks failure of the applications requesting the actions, with attendant risk to equipment, plant and possibly human life. This International Standard specifies interactions between remote applications and defines the externally visible behavior provided by the Type 2 fieldbus application layer. The purpose of this document is to define the protocol provided to a) define the wire-representation of the service primitives defined in this document, and b) define the externally visible behavior associated with their transfer. This document specifies the protocol of the Type 2 fieldbus application layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI application layer structure (ISO/IEC 9545). This fourth edition includes the following significant technical changes with respect to the previous edition: - clarifications of response PDU formats in case of failure in 4.1.5; - clarifications of connection request priority definition and handling in 4.1.6.5 and 4.1.6.6; - clarification of connection remaining path in 4.1.6.12; - extensions of general syntax in 4.1.8.1; - extensions and clarifications of Identity object PDUs in 4.1.8.2; - updates of Assembly object PDUs in 4.1.8.4; - extensions and clarification of Time sync object PDUs in 4.1.8.6; - updates of Parameter object PDUs in 4.1.8.7; - extensions of Connection Manager object PDUs in 4.1.8.8; - clarifications of Connection object PDUs in 4.1.8.9; - extensions and clarifications of message and connection paths in 4.1.9; - updates of object and service class codes in 4.1.10 and error codes in 4.1.11; - updates of data types in 4.2.4, 5.1.3 and 5.2.3; - updates of the encapsulation abstract syntax in 4.3; - updates to the DLL mapping protocol machine 2 in Clause 11; - miscellaneous editorial corrections.

This document addresses the setting and implementation of C&E matrices for a consistent
use in engineering activities. It aims to describe a simple format used to support a consistent
exchange of information between different engineering disciplines involved in project or
maintenance activities. The document defines the minimum requirements of the C&E matrix
content, which is derived from existing design documents, for example P&ID or verbal
descriptions.
The transfer of the relations defined in C&E matrices into a functional or source code for the
application programming of PLC/DCS is out of the scope of this document. In addition, this
document does not cover the implementation of complex and/or sequential logics at a
dedicated automation platform, which will require additional stipulations to be done/ followed.
It is understood, that C&E matrices in fact can be used to document the fault reactions of the
plant equipment and therefore can be used as reference point for the necessary safety
verifications to be applied.
C&E matrices as defined in this document do not have the same scope as Fishbone or
Ishikawa diagrams, which are often named in the literature as cause and effect diagrams.

This document specifies basic requirements for the installation of media for communication networks within and between the automation islands, of industrial sites. This standard covers balanced and optical fibre cabling. It also covers the cabling infrastructure for wireless media, but not the wireless media itself. Additional media are covered in the IEC 61784-5 series. This document is a companion standard to the communication networks of the industrial automation islands and especially to the communication networks specified in the IEC 61158 series and the IEC 61784 series. In addition, this document covers the connection between the generic telecommunications cabling specified in ISO/IEC 11801-3 and the specific communication cabling of an automation island, where an automation outlet (AO) replaces the telecommunication outlet (TO) of ISO/IEC 11801-3. NOTE If the interface used at the AO does not conform to that specified for the TO of ISO/IEC 11801-3, the cabling no longer conforms to ISO/IEC 11801-3 although certain features, including performance, of generic cabling may be retained. This document provides guidelines that cope with the critical aspects of the industrial automation area (safety, security and environmental aspects such as mechanical, liquid, particulate, climatic, chemicals and electromagnetic interference). This document does not recognise implementations of power distribution with or through Ethernet balanced cabling systems that are not specified in IEEE 802.3af and in IEEE 802.3at. This document deals with the roles of planner, installer, verifier, and acceptance test personnel, administration and maintenance personnel and specifies the relevant responsibilities and/or gives guidance.

This part of the IEC 62443 series provides detailed technical control system requirements (SRs) associated with the seven foundational requirements (FRs) described in IEC 62443‑1‑1 including defining the requirements for control system capability security levels, SL-C(control system). These requirements would be used by various members of the industrial automation and control system (IACS) community along with the defined zones and conduits for the system under consideration (SuC) while developing the appropriate control system target SL, SL-T(control system), for a specific asset. As defined in IEC 62443‑1‑1 there are a total of seven FRs: a) Identification and authentication control (IAC), b) Use control (UC), c) System integrity (SI), d) Data confidentiality (DC), e) Restricted data flow (RDF), f) Timely response to events (TRE), and g) Resource availability (RA). These seven requirements are the foundation for control system capability SLs, SL-C (control system). Defining security capability at the control system level is the goal and objective of this standard as opposed to target SLs, SL-T, or achieved SLs, SL-A, which are out of scope. See IEC 62443‑2‑1 for an equivalent set of non-technical, program-related, capability SRs necessary for fully achieving a control system target SL.

This part of IEC 62443 specifies a comprehensive set of requirements for security capabilities for IACS service providers that they can offer to the asset owner during integration and maintenance activities of an Automation Solution. Because not all requirements apply to all industry groups and organizations, Subclause 4.1.4 provides for the development of Profiles that allow for the subsetting of these requirements. Profiles are used to adapt this document to specific environments, including environments not based on an IACS. NOTE 1 The term “Automation Solution” is used as a proper noun (and therefore capitalized) in this part of IEC 62443 to prevent confusion with other uses of this term. Collectively, the security capabilities offered by an IACS service provider are referred to as its Security Program. In a related specification, IEC 62443-2-1 describes requirements for the Security Management System of the asset owner. NOTE 2 In general, these security capabilities are policy, procedure, practice and personnel related. Figure 2 illustrates how the integration and maintenance capabilities relate to the IACS and the control system product that is integrated into the Automation Solution. Some of these capabilities reference security measures defined in IEC 62443-3-3 that the service provider must ensure are supported in the Automation Solution (either included in the control system product or separately added to the Automation Solution).
