By using a Sercos® III Soft-Master, a Sercos III master device can be implemented without specific FPGAs or ASIC Sercos III hardware controller. Instead, a standard Ethernet controller is used and the Sercos III hardware functions are emulated in a host-based driver software. With this implementation approach, a sufficient real-time performance can be ensured for a large number of applications. If an Ethernet controller is used that operates with multiple queues and a telegram scheduler (e.g., the INTEL I210), a synchronicity similar to that of a hardware-based master can be achieved. Using an Ethernet TSN based SoftMaster, it is possible to use Sercos devices and any other Ethernet devices in a common Ethernet TSN network infrastructure.
