Machine-to-machine (M2M) communication is a key enabling technology for industrial internet of things (IIoT)-empowered industrial networks, where machines communicate with one another for collaborative automation and intelligent optimisation. This new industrial computing paradigm features high-quality connectivity, ubiquitous messaging, and interoperable interactions between machines. However, manufacturing IIoT applications have specificities that distinguish them from many other internet of things (IoT) scenarios in machine communications. By highlighting the key requirements and the major technical gaps of M2M in industrial applications, this article describes a collaboration-oriented M2M (CoM2M) messaging mechanism focusing on flexible connectivity and discovery, ubiquitous messaging, and semantic interoperability that are well suited for the production line-scale interoperability of manufacturing applications. The designs toward machine collaboration and data interoperability at both the communication and semantic level are presented. Then, the application scenarios of the presented methods are illustrated with a proof-of-concept implementation in the PicknPack food packaging line. Eventually, the advantages and some potential issues are discussed based on the PicknPack practice.
机器对机器（M2M）通信是工业物联网（IIoT）赋能的工业网络的一项关键使能技术，在这种网络中，机器相互通信以实现协作自动化和智能优化。这种新的工业计算范式具有高质量连接、无处不在的消息传递以及机器之间可互操作的交互等特点。然而，制造业IIoT应用具有一些特殊性，使其在机器通信方面有别于许多其他物联网（IoT）场景。通过突出工业应用中M2M的关键要求和主要技术差距，本文描述了一种面向协作的M2M（CoM2M）消息传递机制，该机制侧重于灵活连接与发现、无处不在的消息传递以及语义互操作性，非常适合制造应用在生产线规模上的互操作性。文中展示了在通信和语义层面针对机器协作和数据互操作性的设计。然后，通过在PicknPack食品包装生产线中的概念验证实现来说明所提出方法的应用场景。最后，基于PicknPack实践讨论了其优点和一些潜在问题。
