NORTHBROOK, Ill., Oct. 29, 2015 — UL (Underwriters Laboratories), a global safety science organization, released a whitepaper on Programmable Logic Controllers and the impact of IEC 61010-2-201, as well as related training, to support product designers and compliance engineers in meeting upcoming new certification requirements.
The free whitepaper, Programmable Logic Controllers and IEC 61010-2-201, provides an overview of PLC requirements as presented in IEC 61010-2-201 and the technical changes that PLC manufacturers must address in the certification process for new and modified PLC designs.

Programmable logic controllers (PLCs) - introduced in the late 1960s - have become essential to the operation of all types of production equipment, especially in industrial facilities. Recently, global PLC requirements have been harmonized to reduce the regulatory compliance burden on manufacturers. The technical requirements were harmonized in the 2013 publication of IEC 61010-2-201 Part 2-201. Effective April 2016, IEC 61010-2-201 will serve as the basis for PLC certification.
To augment the new PLC whitepaper, UL also offers a training course designed for PLC product designers and regulatory compliance engineers. The course covers the key elements of UL61010-1 and the major differences between UL508 and IEC 61131-2, including:
- Differences between UL 508 and IEC 61131-2 , between UL 508 and IEC 61010-1,-2-201
- How the transition to IEC 61010-2-201 affects existing certified products and new product submittals
- Specific clauses in IEC 61010-2-201 Part 1: General requirements
- Specific clauses in IEC 61010-2-201 Part 2: Particular requirements for control equipment
- How the combination of UL and IEC requirements could help in international certification
- End use applications certified to IEC 61010-2-201
