A safety system can come together using the Mechatrolink network by adding a safety master such as a safety PLC and safety slaves, such as safety I/O devices, to the existing system. There is no requirement for special cabling to connect Mechatrolink Safety compliant devices; just use standard Mechatrolink cables. You can connect up to 61 safety slave devices. The Mechatrolink Safety protocol and the Mechatrolink standard protocol can co-exist on the same network.

Mechatrolink is the most widely used motion control network in Asia. The certification of the Mechatrolink field network for safety makes it possible for MMA members to build motion control and machine control systems for use in applications that comply with safety standards. The MMA is a group of Mechatrolink product developers and users who promote the use of Mechatrolink, an industrial network optimized for motion control.

Mechatrolink connects devices such as servo motors, servo amps and I/O to each other and to motion controllers such as PLCs, PACs and motion controllers. Mechatrolink is available in RS-485 and Ethernet versions, operates at speeds up to 100 Mbps, and can support up to 62 simultaneous devices.

The MMA’s Safety Working Group developed the specifications for the safety communications protocol. The Safety Working Group consists of seven corporate members: Inter Factory Partners Co., Ltd.; Digital Electronics Corporation; Nikki Denso Co., Ltd.; HIMA Japan; Magnescale Co., Ltd.; Yaskawa Electric Corporation; and Yokogawa Electric Corporation.
