IEC 63365:2022 applies to products used in the process measurement, control and automation industry. It establishes a concept and requirements for the digital nameplate and provides alternative electronically readable solutions (e.g. 2D codes, RFID or firmware) to current conventional plain text marking on the nameplate or packaging of products. The digital nameplate information is contained in the electronically readable medium affixed to the product, the packaging or accompanying documents. The digital nameplate information is available offline without Internet connection. After electronic reading, all digital nameplate information is displayed in a human readable text format. The digital nameplate also includes the Identification Link String according to IEC 61406-1 which provides additional online information for the product. This document does not specify the contents of the conventional nameplate, which are subject to regional or national regulations and standards.

This Technical Report (TR) explains and provides guidance on the common application of IEC 61508 and IEC 62443 in the area of industrial-process measurement, control and automation. This document may apply to other industrial sectors where IEC 61508 and IEC 62443 are applied.

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.

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.
