Analog Integration Drives Factory Integration

By:

John Mossman, Control & Automation Marketing

Distributed intelligence, smart machines, smart sensors, and the integration of factory data with business-management systems

(information technology or IT) allows optimization of not only the factory process, but also material handling, machine utilization,

scheduling, reporting, and throughput.

A similar version appears on EDN, December 7, 2013.

Introduction

Advances in analog and mixed-signal ICs have contributed greatly to unprecedented combinations of factory productivity,

efficiency, quality, and safety. These ICs enable higher system performance, increasingly accurate measurements, robust

communication, lower power, and higher levels of security. They are central to factory systems that act rapidly on large numbers

of sensor-based measurements that precisely control material handling, processing steps, power and temperature, and

Integrated factories exploit distributed intelligence, pushing computational resources and decision making out of the control

room and into widely dispersed process machinery. This shift in system architecture delivers data to management personnel in

almost real time. It eliminates data-processing bottlenecks. It allows management to deploy more measurement and control

nodes, and to act on significantly larger sets of process data.

The benefits of distributed intelligence to the factory floor can actually be summarized in a single concept: uptime. Factories will

reduce measurement-to-control feedback latencies; experience better reporting of process efficiency, throughput, WIP (work-in-

progress) status, and machine utilization; and lower maintenance costs.

Benefits to the company, however, extend far beyond the factory floor. Integrated-factory systems provide up-to-the-minute

workflow data, which, when combined with supply-chain intelligence, allow operations to optimize their scheduling and inventory

management. Worldwide sales and distribution management can act on precise and timely factory productivity data.
