International standards

The international standards that are based on Yaskawa’s initiative.

Standard No.TitleAbstractNotes
IEC 61158-1~6Industrial communication networks – Fieldbus specificationsIEC 61158-1 to -6 are fieldbus specifications of MECHATROLINK-II, MECHATROLINK-III, MECHATROLINK-4 and Σ-LINK II adopted in 2014 as one of the international standards for industrial communication networks. ※MECHATROLINK-4 and Σ-LINK II completed additions to these standards in March 2023.
IEC 61784-1, 5Industrial communication networks – ProfilesIEC 61784-1,-5 are network profile and physical layer specifications of MECHATROLINK-II and MECHATROLINK-III adopted in 2014 as one of the international standards for industrial communication networks. ※MECHATROLINK-4 and Σ-LINK II will be added to these standards in April 2024.
IEC 62246-2Reed contact unitsEstablished a new standard of IEC 62246-2 Ed.1 for heavy-duty reed switches of BestactTM in 2007.Replaced by IEC 62246-1 Ed.2.0
IEC 62246-1Reed switchesRevised the standard of IEC 62246-1 Ed.2 as generic specification for reed switches including BestactTM In 2011.

※ <International standardization of MECHATROLINK>
MECHATROLINK was adopted as the semiconductor/FPD industry international standard SEMI E54.19 in 2007, and in 2014 it was adopted as an international standard (IEC 61158 series and IEC 61784 series) as a fieldbus specialized in motion from Japan. In 2016, it was adopted as the Chinese national standard GB/T 18473-2016.
MECHATROLINK-4 as a new real-time Ethernet and Σ-LINK II, which pursues synchronism in fieldbus sensor/actuator networks, were adopted as international standards (IEC 61158 series and IEC 61784 series) in March 2023. Physical layer specifications are scheduled to be adopted in April 2024.
From Japan to global standards, its high technical standards and ease of use are internationally recognized.
