The SERCOS® MMS motion modules are used to build a distributed automation solution, integrating motion applications with control applications, based on Quantum PLCs. The axis modules and Quantum CPUs communicate either through the Quantum rack or by using the Modbus Plus network. The data transfer is transparent, and does not need any additional application program.

The physical interface between the SERCOS module and the servo drive is done by the SERCOS network, using fiber optic cable. This optic link is entirely digital, and provides communication parameters for the tuning, diagnostics, and operation of both motion control modules and servo drives.
