International standards

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

Standard No.	Title	Abstract	Notes
IEC 61158-1～6	Industrial communication networks – Fieldbus specifications	IEC 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, 2, 5	Industrial communication networks – Profiles	IEC 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 completed additions to these standards in April 2024.
IEC 62246-2	Reed contact units	Established a new standard of IEC 62246-2 Ed.1 for heavy-duty reed switches of Bestact^TM in 2007.	Replaced by IEC 62246-1 Ed.2.0
IEC 62246-1	Reed switches	Revised the standard of IEC 62246-1 Ed.2 as generic specification for reed switches including Bestact^TM 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 were adopted in April 2024.
From Japan to global standards, its high technical standards and ease of use are internationally recognized.
