Programmable Logic Control (PLC) Solution Guide

Industrial Automation Solutions

The Programmable Logic Controller (PLC) is the workhorse of Industrial Control systems. It uses digital and analog I/O modules to interface to sensors, actua-tors and other equipment. These I/O modules must meet stringent electri-cal specifications and designers face challenges in condi tioning and convert-ing these signals. In addition, increas-ing levels of embedded processing and connectivity can be seen on these modules.

The PLC SystemPLCs can be segmented by I/O count and scan rates. They can also be classi-fied as brick type versus modular PLCs. A small or brick PLC has a fixed number of connections for inputs and outputs. Modular PLCs have a chassis (also called a rack) into which are placed modules with different functions. The processor and selection of I/O modules is custom-ized to fit the application. A modular PLC consists of the Central Processing Unit (CPU), a power supply and various I/O modules. The CPU performs the main controller functions like scanning data and running control sequences. The power supply unit converts line power to 24 volts. The I/O modules are used to measure data from sensors and to

control various actuators. Together, the input and output modules along with the central controller form a control loop.

I/O Module TypesI/O modules can be classified as analog input (AI), analog output (AO), digital input (DI) and digital output (DO). They are usually cate go rized into 2-, 4-, 8- and 16-channel modules. I/O modules need to meet stringent electrical specifications such as the IEC 61000-4 family of Electro Magnetic Compatibility (EMC) tests for surge, ESD (Electro static Discharge) and EFT (Electrically Fast Transients). They also need short-circuit and over load protection. All these modules include isolation between the control side and the field side via DC-DC converters and isolation on digital commu nication between the field devices and the digital backplane. Communication over the digital backplane is done by a variety of interfaces (RS-485, CAN, Ethernet, LVDS, etc.) In distributed control system or between equipment industrial fieldbuses (PROFIBUS®, DeviceNet™, CANopen®, Modbus®, EtherCAT®, EtherNet I/P™, PROFINET®, SERCOS®, POWERLINK, etc.) are used for communication. On the following pages we discuss solutions from TI for these various I/O types.

Programmable Logic Control (PLC)Overview

Analog Inputs

Analog input modules capture and measure signals such as tempera-ture, pressure, flow, level, vibration and motion. These parameters are transmit-ted from equipment such as sensors and other field devices on the factory floor in the form of current or voltage. Current loops typically range from 4–20 mA while voltage inputs can be single ended or differential ranging from 0–5V, 0–10V, ±5V and ±10V.

Digital Input

Digital input modules capture and measure digital input signals from a wide variety of sensors like proximity switches, limit switches and push button switches. Inputs typically are 0–24V with tolerances up to 30V. Digital input serializers can be used to serialize a large number of digital inputs allowing higher channel densities in PLC I/O modules.

PowerTo protect against transients and ground loops, the module is electrically isolated from the control side. The design can be customized for perfor mance and cost by using a DC-DC converters. Finally, using LDOs with good PSRR (power supply rejection ratio) to supply the precision analog circuitry will reduce the power supply ripple and preserve system accuracy and resolution.

Connectivity & Interface

Connectivity options ranging from Ethernet ports to UARTs to simple SPI ports are required. Ethernet enables integration of field devices to the corpo-rate enterprise network. There are a

number of fieldbus options – both serial (RS-485, DeviceNet™, PROFIBUS®, CAN, etc.) and Ethernet based. Extended cable reach and diagnostics to debug wire breaks provides system designers

significant value. Integrated digital isola-tion on the interface transceivers is highly desirable to reduce board space.
