OPC Foundation and Sercos International release Sercos OPC UA Companion Specification
OPC基金會(huì)和Sercos國際發(fā)布Sercos OPC UA配套規(guī)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(huì)和Sercos國際宣布，Sercos OPC UA配套規(guī)范版本現(xiàn)已推出。本規(guī)范描述了Sercos設(shè)備模型和Sercos設(shè)備配置文件映射到OPC UA，使得Sercos設(shè)備的功能和參數(shù)可以通過OPC UA以獨(dú)立于供應(yīng)商的方式訪問。該計(jì)劃旨在簡化機(jī)器外圍和監(jiān)控IT系統(tǒng)之間的通信，并支持工業(yè) 4.0關(guān)于語義互操作性的要求。 OPC基金會(huì)和Sercos國際已經(jīng)開始合作，其共同目標(biāo)是改進(jìn)機(jī)器集成，并簡化機(jī)器外圍設(shè)備和更高級IT系統(tǒng)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(jīng)理Peter Lutz表示，“在當(dāng)今的制造系統(tǒng)中，必須整合和維護(hù)許多不同制造商的自動(dòng)化設(shè)備和系統(tǒng)，從而在整個(gè)產(chǎn)品生命周期內(nèi)產(chǎn)生顯著的總體擁有成本（TCO）。同時(shí)，產(chǎn)品規(guī)劃和控制需要流程和機(jī)器的相關(guān)信息，讓制造資源得到有效利用。通過標(biāo)準(zhǔn)化映射可以最大限度地應(yīng)對這一挑戰(zhàn)，該映射將Sercos定義明確的語義與OPC UA Sercos信息模型結(jié)合在一起。應(yīng)用案例涵蓋范圍廣泛，從設(shè)備參數(shù)化和網(wǎng)絡(luò)配置，到能源管理以及預(yù)防性維護(hù)。”

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(guī)則可用不同的實(shí)施方法。一方面，OPC UA服務(wù)器功能可以在Sercos主設(shè)備（例如CNC或PLC）中實(shí)現(xiàn)。另一方面，可以將該功能傳送到Sercos從設(shè)備。在后面這種情況，OPC UA訪問可以與Sercos實(shí)時(shí)通信甚至無需任何Sercos實(shí)時(shí)通信的條件下同時(shí)執(zhí)行。因此，在不放棄Sercos自動(dòng)化總線硬實(shí)時(shí)通信的情況下，與現(xiàn)場總線級的OPC UA保持一致是可能的。
