The [MC]2 Conference is an annual event dedicated to MTConnect, the open-source interoperability standard for manufacturing equipment. The most recent edition of this conference (April 28-30) was a bit different than its three previous occurrences. The theme of this year’s conference was transforming a business with data-driven manufacturing and the industrial Internet of Things. Past conferences focused primarily on the development and implementation of the MTConnect standard, with many of the presentations centered on MTConnect-enabled applications for machine shops, such as machine monitoring. In contrast, this year’s conference covered the broader context in which this standard plays a vital role.

This new tone and perspective for the conference was evident in the opening day keynote address delivered by Bryce Barnes, Cisco’s senior manager of the machine and robot segment. In his introduction, Mr. Barnes cited this definition of the Internet of Things: It is the intelligent connectivity of smart devices by which objects can sense one another and communicate, thus changing how, where and by whom decisions about our physical world are made. He noted that MTConnect is an enabling technology for the Internet of Things in manufacturing.    

Specifically, Mr. Barnes outlined the main principles that give the emerging industrial Internet of Things the power to “connect the unconnected” in the factory environment. He explained that this universal industrial network will be built around open software architecture, open protocols and open data models. Proprietary elements will not be allowed to create barriers for users or developers of applications operating in the Internet of Things. It will be layered, context-driven and identity-based. This structure will minimize risks to data that is transmitted, stored and analyzed, largely by cloud-based applications. It will provide pathways by which systems, data, software and protocols can grow and be renewed.

Mr. Barnes predicted that sensors will continue to proliferate on and in factory machines so that operators can take actions to keep production equipment running.

Following speakers at the conference picked up and amplified a number of these themes. For example, Athulan Vijayaraghavan, CTO of  System Insights, Inc., noted that manufacturing has a particularly urgent need for intelligent conductivity. Manufacturing represents millions of devices, generating immense amounts of data—most of which “falls on the floor,” he said. Not being able to transform this data into information usable for decision-making is a huge loss—and a huge opportunity. MTConnect is helping meet the challenge of gathering, analyzing and presenting this data as developers tackle applications for real-time decision-making (at the process control level), “near-time” decision making (at the process improvement phase) and anytime/anywhere decision-making (at the management level). He stressed that keeping humans in the loop was both necessary and feasible because “people are sources of critical know-how. Developers must invite their feedback and involvement. Systems must provide transparency and knowledge sharing,” he said.

Other presentations offered examples of integrating data about cutting tools, high-speed metrology with laser scanning and robotic automation, and more effective decision-making. In this group of presenters, Chuck Matthews, a “cloud evangelist” with Machining Cloud GmbH, urged manufacturers to create a digital product strategy that represents “the journey you take your customers through and experience that you must optimize to be successful.”

Likely the most closely followed session of the conference was a panel discussion on industrial cybersecurity. Government and industry experts stressed that the threat to a manufacturing company’s data network was real, that attackers can operate from anywhere in the world, and that the danger of these attacks is growing. The good news is that advice and assistance for implementing effective (but not invulnerable) protective measures are more widely available than many companies realize. What is critical is that manufacturers recognize the threat and respond by availing themselves of these resources.

Workshops on the technical aspects of MTConnect development and implementation closed the conference on the afternoon of its third day.
