To start the engagement, EY teams brought an internet of things (IoT) architect to dig deep into the client’s existing machines and systems, the problems they were facing and the best-suited solutions to fix them. The analysis identified two fundamental steps that were required to achieve the client’s objectives:
- Connect to local systems through a hardwired network.
- Deploy an on-premise edge solution to act as a middle layer between local systems and the cloud, which would effectively translate data into a common format that could be visualized in dashboards.
However, EY teams had to address two significant challenges. First, the machinery used several proprietary protocols, such as the OPC Unified Architecture (UA) protocol, and ways of communicating with machines that needed to be followed while using legacy software. This would require a bespoke IoT edge module in order to connect the machinery to the cloud. Second, the legacy systems were supplied by different vendors, which involved sending questions to vendors via the client and ultimately a complex analysis process.
To develop the solution effectively, EY teams involved the client shopfloor teams from the early stages. Maintenance crews wanted to gain machine-level insights by using different dashboards that would set out a procedure to follow and rectify faults quickly. EY teams designed these dashboards in consultation with the crews – the requirements came from them, in terms of widgets, key performance indicators (KPIs) and ease of adoption.
Using these insights, EY teams built a customized Smart Factory solution on the Microsoft Azure cloud platform. The complete shopfloor solution also used the EY organization’s IoT Sphere, which is a sensor-agnostic IoT cloud platform service. The solution helps accelerate technology to quickly generate asset monitoring and predictive analytics capabilities, along with an edge module to effectively translate the old-world machinery and legacy software data sources into cloud-compatible digital elements.
By helping to establish bidirectional, encrypted device communication and data ingestion services together, the solution would be able to compute and store data locally and display it with an intuitive dashboard. The dashboard would be pulled from an edge framework that would enable real-time data insights. Cybersecurity checkpoints were put in place too, so that data could be exchanged between machines and sites with a very low risk of breaches.
