Product Details
CSA Preface
This is the first edition of CAN/CSA-E61131-2, Programmable controllers — Part 2: Equipment requirements and tests, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 61131-2 (second edition, 2003-02), including Corrigendum 1:2004. At the time of publication, IEC 61131-2:2003 and Corrigendum 1:2004 are available from IEC in English only. CSA will publish the French versions when they become available from IEC.
This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.
This Standard was reviewed for Canadian adoption by the CSA Technical Committee on International Standards, under the jurisdiction of the Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee. A list of the members of the Technical Committee is available upon request. This Standard has been approved as a National Standard of Canada by the Standards Council of Canada.
Scope and object
This Part of IEC 61131 specifies requirements and related tests for programmable controllers (PLC) and their associated peripherals (for example, programming and debugging tools (PADTs), human-machine interfaces (HMIs), etc.) which have as their intended use the control and command of machines and industrial processes.
PLCs and their associated peripherals are intended to be used in an industrial environment and may be provided as open or enclosed equipment. If a PLC or its associated peripherals are Intended for use in other environments, then the specific requirements, standards and installation practices for those other environments must be additionally applied to the PLC and its associated peripherals.
This standard also applies to any products performing the function of PLCs and/or their associated peripherals.
Equipment covered in this standard is intended for use in overvoltage category II (IEC 60664-1) in low-voltage installations, where the rated mains supply voltage does not exceed a.c. 1 000 V r.m.s. (50/60 Hz), or d.c. 1 500 V. (If PLCs or their associated peripherals are applied in overvoltage category III installations, then additional analysis will be required to determine the suitability of the equipment for those applications.)
This standard does not deal with the functional safety or other aspects of the overall automated system. PLCs, their application programme and their associated peripherals are considered as components of a control system.
Since PLCs are component devices, safety considerations for the overall automated system including installation and application are beyond the scope of this standard. However, PLC safety as related to electric shock and fire hazards, electrical interference immunity and error detecting of the PLC-system operation (such as the use of parity checking, self-testing diagnostics, etc.), are addressed. Refer to IEC 60364 or applicable national/local regulations for electrical installation and guidelines.
The object of this standard is
- to establish the definitions and identify the principal characteristics relevant to the selection and application of PLCs and their associated peripherals;
- to specify the minimum requirements for functional, electrical, mechanical, environmental and construction characteristics, service conditions, safety, EMC, user programming and tests applicable to PLCs and the associated peripherals.
This Part also specifies
a) service, storage and transportation requirements for PLCs and their associated peripherals (Clause 4);
b) functional requirements for PLCs and their associated peripherals (Clause 5);
c) EMC requirements for PLCs and their associated peripherals (Clause 8);
d) safety requirements for PLCs and their associated peripherals (Clause 11);
e) information that the manufacturer is required to supply (Clauses 7, 10 and 14);
f) test methods and procedures that are to be used for the verification of compliance of PLCs and their associated peripherals with the requirements (Clauses 6, 9 and 12).
The tests are type tests or production routine tests, and not tests related to the ways PLC systems are applied.
