The programmable logic controller is the workhorse of industrial control systems. It uses digital and analog I/O modules to interface to sensors, actuators and other equipment. These I/O modules must meet stringent electrical specifications and designers face challenges in conditioning and converting these signals. In addition, increasing 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 classified 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 customized 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 16channel modules. I/O modules need to meet stringent electrical specifications such as the IEC 610004 family of electro magnetic compatibility (EMC) tests for surge, ESD (electro static discharge) and EFT (electrically fast transients). They also need shortcircuit and over load protection. All these modules include isolation between the control side and the field side via DCDC converters and isolation on the digital commu nication side between the field devices and the digital backplane. Communication over the digital backplane is done by a variety of interfaces (RS485, CAN, Ethernet, LVDS, etc.) In distributed control systems 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.

Temperature sensor interface module for programmable logic controllers (PLC)
The TIDA-00018 reference design enables faster development of high precision temperature measurement solutions using 24-bit delta-sigma ADC and most widely used temperature sensors like thermocouple and RTD. The design guide will address the sensor signal conditioning, thermocouple cold junction compensation, ratiometric measurement technique for RTD, recommended software flow, sensor linearization, sensor diagnostics, transient protection, PCB layout and other practical design considerations for achieving high precision robust design for temperature measurement in industrial applications. The temperature sensor interface module is a fully isolated design, which is essential for small sensor signal measurement. The heart of this reference design is a 24-bit delta-sigma ADC that provides a high resolution, high–integration, low-noise, and low-cost complete sensor analog front-end (AFE) for DC sensing applications. This ADC also makes it suitable to interface with different types of sensors, thus saving board space, reducing design efforts, decreasing the time to market, and lowering BOM cost. Furthermore, external protection circuitry has been successfully tested for compliance with regulatory IEC61000-4 EFT, ESD, and surge standards. Compliance to IEC61000-4 is necessary to ensure that the design not only survives but also perform as intended in the harsh/noisy industrial environment.

• Wide input voltage range: 18 to 30 V (24 VNOM)• Non-Isolated output: 3.3 V with 50 mA• Three isolated outputs: +15 V with 30 mA -15 V with 30 mA +5 V with 4 0mA• Small form factor for space constrained I/O cards 51 x 51 x 8 mm (L x W x H)• Primary-side regulation (no need for optocoupler) increases lifetime reliability
Adaptive power supply for PLC analog output module with output channel protection
The TIDA-00231 is a reference design for an industrial programmable logic controller (PLC) analog output module. The design provides a unique power saving solution for a digital-to-analog converter (DAC)-based analog current output module with an adaptive power supply. This adaptive power supply dynamically regulates the AVDD supply of the DAC and limits power losses to < 50 mW for typical load resistance of > 300 Ω. The analog output can source current up to 24 mA. This reference design includes the necessary on-board protection circuit and has been tested to IEC61000-4 standard EFT, ESD, and surge requirements with I/O Controller platforms. The protection circuitry does not negatively affect the design and test results showed typical unadjusted errors were less than 0.2% FSR and calibrated accuracy is 0.05%.
• 16-bit user configurable analog current output• Accuracy • Un-calibrated better than ±0.2% FSR at 25°C• Calibrated better than ±0.05% FSR at 25°C• Adaptive power supply reduces system power dissipation- power losses across
FET are limited to < 50 mW for typical load resistance > 300 Ω• Reverse voltage protection for analog output• On-board isolated Flybuck™ power supply with inrush current protection• Designed to comply with IEC61000-4 standards for ESD, EFT, and surge
Isolated DC/DC power supply for PLC analog input and output modules
The TIDA-00401 reference design is an isolated DC/DC turn-key solution. For a 10 W isolated power supply with wide input voltage range, no opto-coupler feedback and low number of external components the Flybuck™ topology is superior to a flyback design. The single side populated PCB board provides a convenient tool for evaluation and on-the-fly optimization of the design, with adequate headers, jumpers and test points for applications like PLC analog Input/Output modules.
• Isolated DC/DC power supply for 15 V to 36 V Input, up to 10 W of output power• Low quiescent current up to 20 mA• Open-loop, optocoupler-less design• Synchronization output and fixed switching frequency enable use in noise
sensitive applications• Flexible configurable board enables easy evaluation and modification• Design guide provides detailed description and performance test data
16-Channel status LED driver for PLC modules reference design
The objective of the TIDA-00560 reference design is to demonstrate a multi-channel LED driver as required in PLC I/O modules to indicate the status of several analog, digital input, and output channels. Important requirements for such a design like low static current, low component count, minimal PCB requirements, and an integrated LED diagnostic features are addressed with this design. The two-layer single-side component mounted board is compatible with the BeagleBone cape specification for rapid evaluation with the BeagleBone platform.
• 16-channel shift register with wide range constant current sinks (2-35 mA)• Two-level selectable LED brightness to compensate for ambient light• Diagnostic features: LED open and LED shorted to ground• Standardized SPI connects seamlessly to standard processors• Number of channels can be increased by daisy-chaining multiple LED driver
devices• BeagleBone cape support for easy evaluation
Ultra-small 1 W, 12 V-36 V iso power supply for analog prog logic controller modules
Analog input and output modules are a standard component in programmable logic controllera (PLC) or distributed control systems (DCS). More channels per module and slimmer modules bring design challenges to the isolated power supply in those modules. Anyone facing those challenges will benefit from TIDA-00237, as the total design footprint is less than 2.54x2.54 mm and less than 5 mm height. It uses a Flybuck approach which means no optocoupler feedback with wide input voltage range of 12V-36 V. The design provides ±15 V and 5 V isolated, low noise outputs optimal for driving a data converter or analog front end.
• Wide input voltage range: 12 V to 36 V (24 VNOM)• 3 isolated outputs: 15 VISO at 3 0mA ultra low noise, -15 VISO at 30 mA ultra
low noise, 5 VISO at 40 mA• ±2.5% output voltage accuracy• Ultra low profile < 5 mm• IEC 61131-2 compliant

Industrial Ethernet for industrial automation exist in more than 30 industrial standards. Some of the well-established real-time Ethernet protocols, like EtherCAT, EtherNet/IP, PROFINET, Sercos III and Powerlink require dedicated MAC hardware support in terms of FPGA or ASICs. The programmable real-time unit inside the Industrial Communication Subsystem (PRU-ICSS), which exists as HW block inside the Sitara processors family, replaces FPGA or ASICS by a single chip solution. A firmware in the PRU-ICSS detects the type of industrial Ethernet protocol and loads the appropriate industrial application during run-time into the Sitara processor. The TIDEP0032 reference design describes the multi-protocol industrial Ethernet protocol detection firmware for PRU-ICSS.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding thirdparty products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safetyrelated requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applicationsrelated information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safetycritical applications.
In some cases, TI components may be promoted specifically to facilitate safetyrelated applications. With such components, TI’s goal is to help enable customers to design and create their own endproduct solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar lifecritical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer’s risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of nondesignated products, TI will not be responsible for any failure to meet ISO/TS16949.
