TÜV certifies Mechatrolink Network Safety Protocol
19 September 2011
Mechatrolink Members Association (MMA) has received confirmation that its Mechatrolink motion control network meets industry safety standards. Certification was received after an independent third party confirmed that these specifications satisfied the requirements of IEC61508 safety integrity level SIL3.
The Mechatrolink network can be used to construct a safety system through the addition to the existing system of a safety master, for example a safety PLC, and safety slaves such as safety I/O devices. No special cabling is required for connecting Mechatrolink Safety compliant devices; standard Mechatrolink cables can be used. Up to 61 safety slave devices can be connected. The Mechatrolink Safety protocol and the Mechatrolink standard protocol can co-exist on the same network.
Mechatrolink is said to be the most widely used motion control network in Asia, and 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.
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. It is available in both RS-485 and Ethernet versions, operates at speeds up to 100 Mbps, and can support up to 62 simultaneous devices.
