OPC Foundation and Sercos International release Sercos OPC UA Companion Specification
OPC基金會和Sercos國際發布Sercos OPC UA配套規范

July 26, 2017 - The OPC Foundation and Sercos International announced that the Sercos OPC UA Companion Specification Release is now available. This specification describes the mapping of the Sercos device model and the Sercos device profiles to OPC UA, so that functions and parameters of Sercos devices are made accessible via OPC UA in a vendor-independent manner. This initiative aims at simplifying the communication between machine periphery and supervisory IT systems and to support the requirements of Industrie 4.0 regarding semantic interoperability. The OPC Foundation and Sercos International started their collaboration with the common aim to improve the machine integration and to simplify the communication between machine periphery and higher-level IT systems.

2017年7月26日——OPC基金會和Sercos國際宣布，Sercos OPC UA配套規范版本現已推出。本規范描述了Sercos設備模型和Sercos設備配置文件映射到OPC UA，使得Sercos設備的功能和參數可以通過OPC UA以獨立于供應商的方式訪問。該計劃旨在簡化機器外圍和監控IT系統之間的通信，并支持工業 4.0關于語義互操作性的要求。 OPC基金會和Sercos國際已經開始合作，其共同目標是改進機器集成，并簡化機器外圍設備和更高級IT系統之間的通信。

“In today’s manufacturing systems automation devices & systems from many different manufacturers have to be integrated and maintained, resulting in significant total cost of ownership (TCO) during the entire product life cycle. At the same time product planning and control require process and machine related information to facilitate the efficient use of the manufacturing resources. This challenge can be faced best with a standardized mapping which brings together the well-defined semantics of Sercos with the OPC UA Sercos information model. Use cases cover a broad range from device parametrization and network configuration up to energy management and preventive maintenance”, states Peter Lutz, Managing Director of Sercos International.

Sercos國際董事總經理Peter Lutz表示，“在當今的制造系統中，必須整合和維護許多不同制造商的自動化設備和系統，從而在整個產品生命周期內產生顯著的總體擁有成本（TCO）。同時，產品規劃和控制需要流程和機器的相關信息，讓制造資源得到有效利用。通過標準化映射可以最大限度地應對這一挑戰，該映射將Sercos定義明確的語義與OPC UA Sercos信息模型結合在一起。應用案例涵蓋范圍廣泛，從設備參數化和網絡配置，到能源管理以及預防性維護。”

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制定的映射規則可用不同的實施方法。一方面，OPC UA服務器功能可以在Sercos主設備（例如CNC或PLC）中實現。另一方面，可以將該功能傳送到Sercos從設備。在后面這種情況，OPC UA訪問可以與Sercos實時通信甚至無需任何Sercos實時通信的條件下同時執行。因此，在不放棄Sercos自動化總線硬實時通信的情況下，與現場總線級的OPC UA保持一致是可能的。
