The IPC requirements of complex control

The IPC requirements of complex control
As automation technologies and the Industrial Internet of Things (IIoT) become more commonplace in modern manufacturing, the requirements of control hardware increase accordingly. However, the importance of this is often overshadowed by the focus on new sophisticated software. This article explains why manufacturers should take a holistic approach to complex control.

For industrial businesses, much of the past decade has been marked by a recurring idea, espoused by forward-thinking business leaders and industrial software and sensor companies alike: the IIoT is coming. Driven by data, connected systems and new industrial network topologies, this concept would revolutionise industry and early adopters would greatly benefit from enhanced efficiency, productivity and profitability.

Countless reports in recent years have reinforced the imminent arrival of the IIoT. In 2019, Microsoft’s IoT Signals report stated that, by the end of 2021, 94 per cent of businesses will use IoT in some capacity. Yet fast-forward to the fateful year and a survey by Ubisense identifies that 43 per cent of manufacturers no longer understand the value of IoT.

Unquestionably, a contributing factor to this uncertainty around the value of IoT is how the concept has been presented in recent years. Whereas IoT and connected devices are new ideas in some markets, they are a long-established norm for many manufacturers. When we consider IIoT simply as connected industrial systems and advanced automation technologies, more manufacturers are aware of the intrinsic value to their operations — and this is reflected in how well these technologies have been adopted in recent years.

However, the implied distinction between automation technology and IIoT has led some business leaders down a route of believing that software is the core focus for digitising their operations. While software certainly plays an integral role, it’s vital that hardware — in particular, industrial PCs (IPCs) — are considered.

For example, the right software package can allow plant managers to ensure that data is communicated and managed in the right way, or that complex control programs can be run. However, if the IPCs at the field-level are unable to provide the computing capacity required to process control or system data, the software package is unable to provide the best value.
