The Industry 4.0, together with the Industrial Internet of Things (IIoT), enable to transfer information, analysis, and data over the internet, improving business productivity through rapid changes in production scope in an increasingly volatile market. In this scenario, the Reference Architecture Model for Industry 4.0 (RAMI 4.0) was defined the elements of I4.0 in a three-dimensional layer model. One of the major challenges for adopting RAMI 4.0 is the development of solutions that support the functionality of each layer and the necessary interactions among. Despite of many studies developing RAMI 4.0 compatible solutions, there are very few studies focusing on the top layers, such as Functional and Business. This research developed a business interface for flexible manufacturing in I4.0 focusing on the Functional and Business layers of RAMI 4.0. The interface uses concepts of Service-Oriented Architecture and Application Programming Interfaces (APIs) and provides a fully API-based interface to easily and scalable exchange information from the factory to clients. The Order Orchestrator is the main module for interaction to both sides, handling production in the factory, such as orders and items production updates from the stations, also, from the clients-side, using the API Gateway, the system is able to insert new orders, delete orders already in production and even modify an order that is currently in production to become a different final good, all of that receiving a response in matter of seconds. The API Gateway based in RESTful APIs is scalable and easy to integrate. The client can manage orders in its backend integration as required, using its own Enterprise Resource Planning (ERP) functions or via standard software connected to computer, gives a major advantage to the factory’s clients as they can quickly respond to market changes, orchestrating changes in their production orders. The business interface was tested and validated in an I4.0 factory-based simulated scenario of clothing production, managing different production orders and changes. This research shows how a combination of the Order Orchestrator in the Functional layer and API Gateway in the Business layer brings a Product as a Service perspective for flexible production and manufacturing, opening space to improve the way of factories and production systems interact with clients.
