Using micro/mini PLC/PAC in the Edge Computing Architecture

A programmable logic controller (PLC) is the core of any industrial automation. For many years, PLC is used mostly to solve logical control tasks. Increasing processor performance and memory capacity, PLCs have the ability to handle a number of different and more complex tasks that are no longer just logical type. This kind of controller is the Programmable Automation Controller (PAC). In industrial control systems are present different kinds of architecture and concepts for integration in enterprise information systems. Edge computing architecture is one of them. In this paper is described a comparison of performance some of the micro/mini PLC/PAC in order to find how of micro/mini PLC/PAC can fit in the Edge Computing Architecture.
