Mechatrolink Members Association

From EverybodyWiki Bios & Wiki

Mechatrolink Members Association (MMA) is a worldwide group of over 3,000 Mechatrolink product developers and users of Mechatrolink, an open field network. The headquarter is located in Iruma, Japan. MMA has eight overseas departments to provide technical support to its members and ensure the functionality of the worldwide standard by awarding certification to compliant products, regardless of manufacturer.

History[edit]

The precursor of MMA, the Mechatrolink Members Club was founded 2003 in Japan. The precursor of MMA connected users for two years until MMA in its current form was founded in 2005.[1] The first oversea departments in China, Europe, South Korea and the United States were established one year later, as focus on local support possibilities grew stronger. In the following years, several other branches opened, namely in Taiwan (2013), India (2014) and the ASEAN branch (2016). While growing to over 3,000 members today, MMA has continued to support the newer versions of Mechatrolink (ML II/III/4) as well as other technologies. It has achieved the admission of Mechatrolink in several standards, for example IEC 61158 / 61774[2] or the China National Standard (GB/T18473-2016):[3].

There are several memberships tiers available, both free and paid, which differ in some privileges for the users. Members gain technical support through the organization, may participate in seminars or obtain the MMA specifications and subsequently take part in the MMA certification programs.[5]

Certification[edit]

To ensure compliance between all Mechatrolink products, regardless of manufacturer, the MMA offers a certification test. To achieve the certificate, the components need to be screened at an MMA test site in either China or Japan. There, the product’s components, circuits, noise resistance and interconnectability will be surveyed before the certification is awarded.

Technologies[edit]

The following technologies are supported by MMA[6]

Mechatrolink 1 – the first version of Mechatrolink developed mainly for the Yaskawa products in the early 1990s.

Mechatrolink-II – a bus network allowing a maximum of 30 node addresses. All slave stations on the network can be run synchronously.

Mechatrolink-III – an upgrade of Mechatrolink-II with added high-speed communications with a maximum speed of 100Mbit/s by applying Ethernet technology to the physical layer. The number of slaves was increased to 62.

Mechatrolink 4 – an upgrade of Mechatrolink-III with improved performance to support larger scale manufacturing.

∑-Link II – developed to connect sensors and I/O devices to the same network. The ∑-Link II master (which is simultaneously the ML4 slave) operates as a gateway between the host controller and the sensors with synchronized transmission timing.
