Open system options continue to emerge from nontraditional suppliers and standards groups, and this is a trend that I expect will accelerate and enable multivendor interoperability at all levels of the system architecture.
There are some intriguing Industry 4.0/Smart Manufacturing open source edge platforms emerging, which are leveraging knowledge and technologies from the general computing and IoT industry. In addition to the efforts coming out of specific countries mentioned in trend #2, several multinational organizations and corporations have been driving manufacturing open architecture initiatives. Some of the more prominent examples going into 2021 include the following.
MTConnect
The MTConnect standard (ANSI/MTC1.4-2018) offers a semantic vocabulary for manufacturing equipment to provide structured, contextualized data with no proprietary format. The MTConnect Institute is a 501(c)(6) not-for-profit standards development organization for the MTConnect standard (ANSI/MTC1.4-20. Its membership is made up of over 400 companies and research organizations in discrete manufacturing including automotive, aerospace, medical, and other industries as well as software developers, system integrators, and research organizations supporting those industries. Membership is free and open to anyone with a stake in MTConnect.OPC Foundation
The OPC Foundation continues to add OPC UA semantic models and schema from to further the global standard for interoperability. OPC UA is becoming an important and IT/OT integration mechanism. OPC UA is a framework for industrial interoperability models that provide a syntactical definition of information that can be communicated communication methods, including modern industrial protocols, Ethernet, cellular, and machine manufacturers describe the object-oriented information of their system and rights with integrated information technology (IT) security.Eclipse Foundation
The Eclipse Foundation’s open standards for Industry 4.0 are designed to allow for interoperable, modular and vendor independent. The following relevant standards are different open source projects:- OPC UA - Eclipse Milo is a full implementation of OPC UA.
- MQTT - Eclipse Paho and Eclipse Mosquitto provide a client and broker implementation messaging protocol.
- Production Performance Management Protocol (PPMP) is a payload specification required to do performance analysis of production facilities.
- oneM2M – oneM2M is a service layer standard that defines common service functions shared by applications, gateways, and devices. oneM2M includes defined interworking such as OSGi, DDS, OPC UA, and Modbus so that industrial data can be aggregated applications uniformly.
- Eclipse 4diac provides the development tools and the runtime to create control based on IEC 61499. 4diac also integrates OPC UA and MQTT into PLC to ease
- IoT Gateway Eclipse Kura provides a portable Java/OSGi edge computing framework Gateways that can be deployed into Industry 4.0 solutions. Kura supports a wide protocols including OPC UA, Siemens S7, and Modbus. Eclipse Kura also feature adata flow programming tool called Wires. Wires allows to define data collection at the edge by simply selecting components from a palette and wiring them together
- Digital Twin Eclipse Ditto is a framework to create and manage digital twins. Ditto resource-based API that can be used to interact with devices, abstracting from the different device types and how they are connected. It helps to structure the devices aspects of functionality and can optionally enforce data types and data validation device meta model, based on Eclipse Vorto.
EdgeX Foundry
The Linux Foundation’s EdgeX Foundry is a vendor-neutral, open source project providing a common open framework for Internet of Things (IoT) edge computing and an ecosystem of interoperable components that unifies the marketplace and accelerates enterprise and Industrial IoT. The project is aligned around a common goal: the simplification and standardization of Industrial IoT edge computing, while still allowing the ecosystem to add significant value. EdgeX Foundry leverages cloud-native principles, including microservices and platform-independence, but is architected to meet specific needs of the IoT edge. This includes accommodating both IP- and non-IP based connectivity protocols, security and system management for widely distributed compute nodes, and scaling down to highly- constrained devices.
