This book was released on 2018-03-30 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This booklet is the second of a series dedicated to automation recipes created with the PLC (Programmable Logic Controller) and HMI (Human Machine Interface) binomial. The series is aimed at an audience of readers with an elementary knowledge of PLC programming, eager to learn advanced solutions, extensively tested on real systems. In modern computer programming, generally oriented to the development of "object-oriented" software, the developer strives, as much as possible, to resort to so-called "Design Patterns," standard solutions for frequently recurring problems. A design pattern describes a problem, particularly recurring in a given context, and then provide the heart of the solution to this problem. It is therefore possible to successfully reuse this solution, thousands and thousands of times, with the certainty of using an efficient and well-tested solution. In the present series, which deals exclusively with development on PLC-HMI, the term "design pattern" has been replaced by the term "automation recipe" for an easier understanding by the non IT reader. In the chapters of this book we will show in detail an automation recipe that can be reused in any PLC-HMI automation project that uses "electric motors." The recipe has also been optimized for operation with Scada supervision systems. This second book illustrates the automation recipe for measuring and monitoring quantities acquired with 4-20 mA current sensors. In detail, the first section, dedicated to the application domain, analyzes the various types of measurement used to acquire physical quantities such as pressure, level, flow, electric current and temperature.The second section deals with the development of combined software for both PLC and HMI. The logic of the two function blocks (UDFB), Conv4_20mA and AnalogSts are analyzed. The first block shows how to convert from analog 4-20 mA to engineering quantities, while the second one explains how to monitor the status of the analog signal based on preset parameters such as set-point, hysteresis, dead band, operational thresholds and first and second level alarms. For both functional blocks are developed in detail the relevant screens for displaying the values, the local monitoring of the states and the setting of adjustment parameters. In addition to the logic of the function blocks, two auxiliary subroutines are also discussed, VirtualAI and Init, to be called only once (singleton) in the main program. The third section shows, finally, the application of the concepts, developed in the previous chapters, to a concrete case of level control in a waste water pumping station. The HMI solutions have been extensively tested on the OCS, Operator Control System, manufactured by Horner Apg. OCS combines a Controller, Operator Interface, Network and I/O into a single product. While the author, has been widely using Siemens, Allen Bradley, GE Fanuc PLCs he has focused the books of this series on the Horner OCSs because Horner provides Cscape, an integrated development environment, extremely easy to use and above all completely free. All the logics, published in the book, have been developed using the IEC61131-3 compliant Ladder language; therefore it is extremely easy to migrate them on almost all the PLCs of other manufacturers. The same applies to HMI screens whose graphic controls are very similar on the different equipment offered on the market. The reader who already has experience with other manufacturers' equipment can therefore continue to use what he knows best.

In the chapters of this book we will show in detail an automation recipe that can be reused in any PLC-HMI automation project that uses machine sequencers. The recipe has also been optimized for operation with Scada supervision systems. The first book deals with electric motors automation while the second with measurement and monitoring quantities acquired with 4-20 mA current sensors. This third book deals with the topics of sequencers for starting / stopping machinery such as pumps or compressors that operate in twin or parallel mode on groups or technological plants. The sequencers process the signals output from a monitoring block of an analogue quantity and send the start command to a certain number of electric motors, which are automated with electrical blocks of type ElectricMotor (see volume 1). They therefore complete the regulation chain of an analogue quantity with digital drives (start / stop). In detail, the first section of this booklet, dedicated to the application domain, analyzes the two types of sequencer: twin for the operation of two machines, one of which is always on stand-by or parallel to start / stop a certain number of machines, generally of the same size, installed in parallel. The second section deals with the development of combined software for both PLC and HMI. The logic of the two functional blocks (UDFB), Mot2Seq and Mot6SEq, and the related display screens, for local monitoring and for setting configuration and timing parameters are illustrated. Finally, the third section shows the application of the concepts developed in a real level control case in a waste water pumping station. All the logics, published in the book, have been developed using the IEC61131-3 compliant Ladder language; therefore it is extremely easy to migrate them on almost all the PLCs of other manufacturers.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a complete and detailed collection of automation recipes for technological systems which is composed of 16 functional blocks, 8 subroutines and the associated graphic pages, expressly designed for monitoring and control, in a PLC-HMI-SCADA context.All the PLC logics and the HMI screens have been applied and extensively tested by the author in thirty years of experience on real automation systems. The PLC code uses the standard ladder 61131-3 language which was chosen to facilitate portability and universality of the code independently of the PLC manufacturer. Each control logic is associated with one or more HMI graphic pages that dynamically display values, texts and allow set-points and manual commands on the local operator panel.The book consists of four sections.The first section contains recipes specially designed for the equipment and sensors automation. It includes five functional blocks: ElectricMotor, very useful for managing commands, statuses, alarms, hours of operation and number of starts for an electric motor; Conv4_20mA a block to be used for the conversion from analog signal to engineering value when 4-20 mA transmitters are used; AnalogSts to be used for monitoring the HighOperating, LowOperating, HighAlarm, LowAlarm, HighReasonability statuses, the hysteresis and the alarm thresholds, depending on the set-point of analog quantities; Mot2Seq and Mot6Seq, twin and parallel sequencers for starting and stopping machinery (from 2 to 6 units).The section also contains three subroutines: VirtualDI, VirtualAI and VirtualDO for decoupling the input / output physical addresses from the internal registers distributed within all the application logic.The second section contains general purpose recipes. It includes three subroutines whose usage is always recommended to the developer: Init to set, at the first scan cycle, default values for the application set points, timers and counters; ScadaCmd to group together the remote command registers coming from the SCADA system; Alarms to set global alarm flags and to group alarm registers. The section also contains four function blocks: SecFlipFlop and Ctrl3P to generate pulse trains for three-point actuators, HighLimitTester to check compliance with the intervention thresholds, WatchDog to monitor the maximum time allowed for the execution of an action, Linear for a real-time linear interpolation within 8 predefined x-axis intervals. The third section exploits the capabilities of the PLC internal clock calendar: the subroutine RTC constructs convenient global flags and registers, for date and time management, to be consumed by other client routines. Six function blocks are also illustrated: TimeValidator verifies the correctness of the hours and minutes fields set by the user on HMI; Load1Enable and Load3Enable enable an output channel respectively on one or three daily bands; DayOfWeekEnabled supports the activation of a single load on the various days of the week, Zone function block aggregates Load1Enable and DayOfWeekEnabled to manage weekly irrigation tables and the last Room function block aggregates Load3Enable and DayOfWeekEnabled to manage building weekly occupancy tables for HVAC systems.Finally, the fourth section deals with issues related to user authentication and authorization. The access subroutine and the associated HMI screen manage the appropriate role and password fields. The navigation of the various pages of the operator panel can therefore be authorized or denied based on the authorized access role.A final chapter shows two examples of the usage of recipes within the main PLC program of a wastewater pumping station and a booster pump system.This book is addressed to a reader who, even if in possession of the basic knowledge on PLC programming, wants to develop, in a very short time, professional automation systems characterized by a great robustness and reliability of the source code.

A design pattern describes a problem, particularly recurring in a given context, and then provide the heart of the solution to this problem. It is therefore possible to successfully reuse this solution, thousands and thousands of times, with the certainty of using an efficient and well-tested solution. In the present series, which deals exclusively with development on PLC-HMI, the term "design pattern" has been replaced by the term "automation recipe" for an easier understanding by the non IT reader. This fourth notebook deals exhaustively with management strategies based on the internal calendar clock of the PLC. The latter, in fact, allows you to easily generate triggers in coincidence of time intervals corresponding to every minute, every 5 minutes, every quarter of an hour, every hour, every day, every month, every year. These triggers are made available to other application program routines in order to schedule totalization or reporting activities on an hourly, daily, monthly and yearly basis. The system variable "day of the week" also allows you to manage differentiated control logics, depending on whether the day in question is between the working days from Monday to Friday, or Saturday rather than Sunday. Within the day, differentiated time intervals can be configured. This possibility is very important for smart electricity management systems in multi-hour tariffs. Occupation tables are typically used to manage the start / stop of air conditioning systems in the residential building sector. Extending the concept of the occupancy schedule it is possible to use the same logic for starting / stopping of the refrigeration system at times of particular loading / unloading of product in the cold rooms. Likewise, this type of logic can also be used to manage the duration and frequency of watering both within the day and the week. This type of recipe therefore has a general use, somehow "transversal" to the various types of technological systems. We can conclude that any type of management and accounting of both electric and thermal energies can not do without the temporal triggers offered by the RTC (Real Time Clock) subroutine. In detail, the first section of this notebook, dedicated to the application domain, illustrates the date clock and the employment or watering tables. The second section deals with the development of combined software for both PLC and HMI. The logic of the RTC (Real Time Clock) subroutine and that of the functional blocks (UDFB), TimeValidator, Load1Enable, Load3Enable, DayOfWeekValidator and Watering are illustrated, along with the relative display screens, local monitoring and configuration parameter settings. Finally, the third chapter shows the application of the concepts developed in a real case of control of an irrigation system. All the logics, published in the book, have been developed using the IEC61131-3 compliant Ladder language; therefore it is extremely easy to migrate them on almost all the PLCs of other manufacturers. The same applies to HMI screens whose graphic controls are very similar on the different equipment offered on the market. The reader who already has experience with other manufacturers' equipment can therefore continue to use what he knows best.

A design pattern describes a problem, particularly recurring in a given context, and then provide the heart of the solution to this problem. It is therefore possible to successfully reuse this solution, thousands and thousands of times, with the certainty of using an efficient and well-tested solution. Patterns can ultimately be considered as "elegantly formalized" best practices, which the programmer is quick to use to simultaneously achieve both an exponential decrease in development time and greater robustness and reliability of the generated code. In the present series, which deals exclusively with development on PLC-HMI, the term "design pattern" has been replaced by the term "automation recipe" for an easier understanding by the non IT reader. In the chapters of this book we will show in detail an automation recipe that can be reused in any PLC-HMI automation project that uses "electric motors." The recipe has also been optimized for operation with Scada supervision systems. In detail the book illustrates the automation recipe for the automation of electric motors powered by three-phase alternating current. The first section, dedicated to a brief introduction to the application domain, illustrates the physical structure of an electric motor and the main types of starting: direct at full voltage and with reduced voltage, obtained with a star - delta switching. The second section deals with the development of combined software for both PLC and HMI. The logic of the main functional block (UDFB), ElectricMotor, as well as the HMI monitoring and local control screens, are analyzed in detail. An auxiliary function block, the twin sequencer Mot2Seq, is then introduced, to explain the pratical usage of ElectricMotor in a real application for twin-pumps automation. The HMI solutions have been extensively tested on the OCS, Operator Control System, manufactured by Horner Apg. OCS combines a Controller, Operator Interface, Network and I/O into a single product. While the author, has been widely using Siemens, Allen Bradley, GE Fanuc PLCs he has focused the books of this series on the Horner OCSs because Horner provides Cscape, an integrated development environment, extremely easy to use and above all completely free.

In the present series, which deals exclusively with development on PLC-HMI, the term "design pattern" has been replaced by the term "automation recipe" for an easier understanding by the non IT reader. This fifth notebook addresses the issue of authentication and authorization of the user; mandatory topic in every computer application project but very neglected in automation projects with PLC. From this point of view the innovative character of the contents and the uniqueness of the topics will surely be appreciated by the reader. In detail, the first section of this notebook, dedicated to the application domain, illustrates the problems related to the authentication and authorization of the user by means of appropriate login and password fields. It is then shown how not only the navigation of the HMI pages can be authorized or denied according to the user's access role, but also that some fields of the screens can be rendered not visible to the unauthorized user. The second section deals with the development of combined software for both PLC and HMI. The logics of the Login subroutine and the LOGIN password access screen as well as the main navigation MENU are explained. Finally, the third section shows the application of the concepts developed in a specific case of a waste water pumping plant. All the logics, published in the book, have been developed using the IEC61131-3 compliant Ladder language; therefore it is extremely easy to migrate them on almost all the PLCs of other manufacturers. The same applies to HMI screens whose graphic controls are very similar on the different equipment offered on the market.

Book excerpt: Widely used across industrial and manufacturing automation, Programmable Logic Controllers (PLCs) perform a broad range of electromechanical tasks with multiple input and output arrangements, designed specifically to cope in severe environmental conditions such as automotive and chemical plants. Programmable Logic Controllers: A Practical Approach using CoDeSys is a hands-on guide to rapidly gain proficiency in the development and operation of PLCs based on the IEC 61131-3 standard. Using the freely-available* software tool CoDeSys, which is widely used in industrial design automation projects, the author takes a highly practical approach to PLC design using real-world examples. The design tool, CoDeSys, also features a built in simulator/soft PLC enabling the reader to undertake exercises and test the examples. Key features: Introduces to programming techniques using IEC 61131-3 guidelines in the five PLC-recognised programming languages. Focuses on a methodical approach to programming, based on Boolean algebra, flowcharts, sequence diagrams and state-diagrams. Contains a useful methodology to solve problems, develop a structured code and document the programming code. Covers I/O like typical sensors, signals, signal formats, noise and cabling. Features Power Point slides covering all topics, example programs and solutions to end-of-chapter exercises via companion website. No prior knowledge of programming PLCs is assumed making this text ideally suited to electronics engineering students pursuing a career in electronic design automation. Experienced PLC users in all fields of manufacturing will discover new possibilities and gain useful tips for more efficient and structured programming. * Register at www.codesys.com www.wiley.com/go/hanssen/logiccontrollers
