without overloading the components involved. In this scenario, using a smart device ensures reliable operation and increased availability, while supporting the maximum workload. Creating a CPS from components both in the control cabinet and in the field The use of the intelligent wiring and communication system is not limited to just the control cabinet. It can even be extended to peripherals using IP67 protection type I/O modules. Intelligent wiring offers clear benefits, as up to 99 devices can be simply and quickly configured as smart devices on a cable up to 600m in length. Motor starters, soft starters, variable frequency drives, circuit breakers, miniature and residual current circuit breakers as well as push-buttons, situated in a high protection class or a suitable small enclosure, can be installed in the exact location in the field where they will form a CPS along with the motor. The real strength is demonstrated by machines with a distributed structure (especially if they conform to the Industry 4.0 system) when expansions are carried out. This is true irrespective of whether expansion occurs when the machine is first being commissioned, when it is already up and running. Problems caused by a lack of space in the control cabinet are a thing of the past, as all the key sensors and actuators are installed in the field. Additional I/O modules for a central PLC are not required.

Conclusion One basic principle is to consistently follow the distributed model. Many industries, mechanical engineering in particular, companies are at an early stage in using this approach, as until now the right technologies have not been available. Obviously conventional, centrally-controlled machines do offer opportunities for connecting to the world of Industry 4.0. However, the lack of seamless connectivity means that these solutions remain workarounds, and the numerous benefits that the Internet of Things could provide for machine design are still untapped. Those companies just beginning to use CPSs and work in terms of a distributed approach will enjoy these benefits sooner rather than later. Eaton has set itself the objective of providing the mechanical

engineering sector with support in making their machines IoT-ready. The power management company is developing components, systems and solutions that enable all customers to implement the basic principles of Industry 4.0 in their products, regardless of whether they are small, compact machines or complex, sprawling systems. One of the company’s core tasks is to help specifically medium- sized mechanical engineering firms to make their products IoT- ready. Within its “Authorised Lean Solution Partner” programme, Eaton collaborates with a network of application specialists to be able to offer customers solutions going beyond the components and wiring solutions.
