New topologies for automation systems
February 2017, System Integration & Control Systems Design


The emergence of the Industrial Internet of Things (IIoT), allows many traditional notions associated with industrial automation systems to be reconsidered. One of the constructs requiring a new perspective is the topology of industrial automation systems. Traditional topologies were based on technological considerations and, as such, did not easily map to plant architectures. This paper analyses the benefits of new topologies that align perfectly with inherent industrial technologies, which are made possible through the adoption of the IIoT.

Introduction

Starting with the introduction of digital computer technology as the delivery vehicle for process control systems in the 1960s and 1970s, industrial control system topologies have been designed for industrial operations based on the limitations and constraints of those digital technologies – not on the topology of the industrial businesses and operations. As a result, the physical and logical topologies of traditional industrial control systems have been fundamentally mismatched. Although these control systems worked and performed their functions, they were difficult to apply and maintain – at least in part due to the fact that their physical and logical topologies did not naturally align with operational and business architectures.

The fundamental topology and functionality of automation systems are on the verge undergoing a significant transformation due to technological advancements, such as big and small data analytics, cloud computing, cyber-physical systems and the IoT. The emerging automation systems will be based on natural industrial architectures (NIT) and defined by the asset architectures in the industrial plants and enterprises, not the technological constraints.

Traditional asset-centric or process-centric topological views

There are two competing perspectives for natural industrial topologies: asset-centric and process-centric. These two perspectives are based on the predominant topological view of an industrial operation. In an asset-centric model, there are processes that are controlled within the context of assets. In a process-centric model, assets are defined as nodes within the overall processes. Traditional machine controls through PLCs have taken an asset-centric perspective from inception because early PLCs were typically aligned to a specific equipment asset. Process controls were based on a process-centric perspective from inception.

The logical topologies of traditional DCS systems were more aligned to industrial processes than the assets due to their evolution from analog process control systems. This process-centric perspective served industry well for simple control loops up to process units. The problem with the process-centric perspective is that it tends to increase in complexity as the process extends to entire units, process areas, plants, and enterprises. In fact, the complexity tends to increase exponentially. Although with considerable effort they could expand to the area, plant, fleet, enterprise and value chain levels, they seldom truly did because the complexity became such a significant barrier.

Technology has progressed to the point at which technological constraints no longer provide barriers to the agility needed to move toward automation systems based on NITs. These emerging systems can naturally converge into overall systems of systems that optimise the performance of each asset, asset set, or entire industrial enterprises. The result is higher levels of industrial performance than ever before. Designing control systems to align with natural industrial topologies is the first step along a path of unprecedented industrial security, safety, efficiency and profitability.
