The mapping rules specified by Sercos can be used for different implementation approaches.On the one hand,the OPC UA server functionality can be implemented in a Sercos master device(e.g.CNC or PLC).On the other hand,it is possible to transfer this functionality to a Sercos slave device.In the latter case,the OPC UA accesses are executed in parallel to the Sercos real-time communication or even without any Sercos real-time communication.Thus,a consistent communication with OPC UA down to the field level is possible without abandoning the hard-real-time communication of the Sercos automation bus.

Sercos制定的映射规则可用不同的实施方法。一方面，OPC UA服务器功能可以在Sercos主设备（例如CNC或PLC）中实现。另一方面，可以将该功能传送到Sercos从设备。在后面这种情况，OPC UA访问可以与Sercos实时通信甚至无需任何Sercos实时通信的条件下同时执行。因此，在不放弃Sercos自动化总线硬实时通信的情况下，与现场总线级的OPC UA保持一致是可能的。
