In today's increasingly competitive global market, efficient industrial production capacity often depends on the speed, accuracy and reliability of each factory's automation system. Even in areas with low labor costs, manufacturers are eager to improve the precision of their automation systems, knowing that failure to do so would jeopardize their position in the global economy.

At the heart of industrial automation is a new generation of advanced smart sensors that keep product lines running, connected to high-performance programmable logic controllers (PLCs) andman-machine interface(HMI) system. Of course, for manufacturers, time is money. As long as the products manufactured can reach the specified quality level, the efficient production line will continue to run as fast as possible. High-speed, reliable sensors must monitor or measure various conditions of the production line very quickly (milliseconds or even faster). After that, the network must transmit this information with a small delay of zui time and without interrupting production. We need a large number of industrial communication protocols to achieve the required key communication performance, such as: PROFIBUS/PROFINET, Ethernet/IP, EtherCAT, POWERLINK, SERCOSIII, etc. In addition, processing components such as PLCs must respond correctly in real time, otherwise productivity will be affected and profits will be lost.

Texas Instruments (TI) has extensive experience in delivering comprehensive high-performance, efficient, and scalable technologies to industrial automation. Texas Instruments' broad family of analog and embedded processors enables customers to design complete system-level solutions. This article focuses on TI's innovative, highly differentiated solutions that make industrial communications cheaper, more accessible, and drive automation and productivity improvements.

　Introduction to Industrial Automation

A typical industrial automation system is generally composed of four parts, which can implement low latency and real-time high-speed communication between them. These four components are: sensor, human-machine interface, PLC and motor drive.

Sensor

Modern factory automation systems increasingly rely on smart sensors for information and data transmission. Once upon a time, sensors were only responsible for monitoring and measuring, but not for analysis. Now, as sensors become more intelligent, they can better evaluate the work they are detecting and complete the task in real time. The many functions of sensors include sensing temperature, motion, optical objects and positions, weight, acceleration, chemical composition, gas, gas pressure or other pressures, liquid flow, and other aspects of the physical world.

　Human Machine Interface (HMI)

The human-machine interface is a unit or subsystem that communicates with the operator. The human-machine interface of most industrial automation systems integrates a graphics display subsystem, such as a touch screen, because such systems are intuitive and easy to learn.

Programmable Logic Controller (PLC)

Generally speaking, PLCs are microcontroller or processor-based systems that receive information from various sensors and system operators distributed throughout the plant. Based on the information provided by these two sources of information, the PLC initiates actions to control the process of the production line.

Motor Driver

Motor drives are some of the machine parts that actually respond to PLC commands. For example, in a car assembly plant, sensors provide information to the PLC about the position of the car's body. The PLC will respond to this information and issue instructions to the motor control unit to control the robotic arm to spot weld the car.

In industrial automation systems, these four parts are connected through high-speed, low-latency networks. This network ensures that the PLC responds quickly to sensor or operator information inputs. In general, today's industrial automation systems are real-time, high-precision systems with decision-making capabilities that enable precise control of high-speed production processes.
