  1. 1. 1 - 8 0 0 - 6 3 3 - 0 4 0 5eCS-2 Control Systems OverviewVolume 13What is a Programmable Controller?What are programmablecontrollers and how dothey work?Programmable controllers are oftendefined as miniature industrial computersthat contain hardware and software usedto perform control functions. A controllerconsists of two basic sections: the centralprocessing unit (CPU) and the input/outputinterface system. The CPU, which controlsall system activity, can further be brokendown into the processor and memorysystem. The input/output system is physi-cally connected to field devices (e.g.,switches, sensors, etc.) and provides theinterface between the CPU and the infor-mation providers (inputs) and controllabledevices (outputs).To operate, the CPU “reads” input datafrom connected field devices through theuse of its input interfaces, and then“executes” or performs the controlprogram that has been stored in itsmemory system. Programs are typicallycreated in ladder logic, a language thatclosely resembles a relay-based wiringschematic, and are entered into the CPU’smemory prior to operation. Finally, basedon the program, the PLC “writes” orupdates output devices via the outputinterfaces. This process, also known asscanning, typically continues in the samesequence without interruption, andchanges only when a change is made tothe control program.Discrete applicationsProgrammable controllers are often usedto control machines or processes that aresequential in nature, using “discrete”inputs and outputs that have definedstates. For example, if a limit switch detectsthe presence of an object, it provides an“ON” signal to the PLC; if no object isdetected, it provides an “OFF” signal. Themachine or device typically performsactions based on time or events in a pre-defined order. The expected sequence istypically interrupted only when anabnormal condition occurs.Process controlapplicationsProgrammable controllers can also controlcontinuous processes that use analog I/O.For example, a temperature sensor mayprovide a variable signal, such as 0-10volts, based on the measurement of anactual temperature. The controllerprogram monitors the sensed valuescontinuously and operates devices thatmay also be analog in nature. This couldinclude setting the position of a valvebetween 0-100% open, or controlling thespeed of a motor. Continuous applicationsare so called because they typically haveno defined start or end once they are initi-ated; they maintain a process in a “steady”operating state.Today’s controllersInitially, devices that exhibited the attrib-utes discussed here were known asProgrammable Logic Controllers (PLCs).This tended to emphasize that the mainfunctionality of these systems was LOGICoperations. As technology has advanced,so have programming languages andcommunications capabilities, along withmany other important features. Thesedevelopments seemed to demand the defi-nition of a new class of controller, theProgrammable Automation Controller(PAC), which combines features of tradi-tional PLCs with those of personalcomputers.In the past, size was typically used to cate-gorize controllers, and was often an indi-cation of the features and types ofapplications it would accommodate.Small, non-modular PLCs (also known asfixed I/O PLCs) generally have lessmemory and accommodate a smallnumber of inputs and outputs in fixedconfigurations. Modular PLCs have basesor racks that allow installation of multipleI/O modules, and will accommodatemore complex applications. With theemergence of PACs, functionality is thedetermining factor in categorizingcontrollers.Which programmablecontroller is right for you?Choosing the most effective controller foryour application depends on a number offactors. To begin the selection process, adrawing of the machine or process is agood start. This can help identify fielddevices and physical requirements forhardware locations. From the drawing, youcan determine how many analog and/ordiscrete devices you will have.Once the field device requirements andhardware locations are defined, you canreview controllers that will meet yourrequirements. See the Controller SelectionWorksheet in this section that will help youwork through the considerations for deter-mining the type of controller you will need,regardless of which manufacturers you areevaluating.

While theyeach share a few attributes with the oth-ers, their differences lie mainly in formfactor and functionality.Programmable Logic ControllerThe Farlex Dictionary defines a PLCas follows: “A programmable micro-processor-based device that is used indiscrete manufacturing to control assem-bly lines and machinery on the shop flooras well as many other types of mechani-cal, electrical and electronic equipmentin a plant. Typically RISC based andprogrammed in a specific-purposeprogramming language, a PLC isdesigned for realtime use in rugged,industrial environments. Connected tosensors and actuators, PLCs arecategorized by the number and type ofI/O ports they provide and by their I/Oscan rate.”PLCs excel at sequential logic and basicanalog control. Their modularity andruggedness make them suitable for awide variety of automation applications.PC-based ControlWith Personal Computer technologybooming in the 1980s and 1990s, therewas a natural progression to considerusing the processing power in these unitsto solve more complicated applicationsthat extended well beyond the realm ofdigital and analog I/O manipulation.These more advanced capabilites couldbe performed far more efficiently byhardware and software native to thecommercial personal computer.Examples of these requirements include:• The need for a Human MachineInterface (HMI) as well as control• Advanced data manipulation andadvanced math functions• Data exchange with businessapplications (spreadsheets,ERP systems)• One or more third-party PC cards, suchas those for motion control or visionsystems• Communication with serial ornetworked field devices• Storage or access to large amounts ofdata• Large number of PID loops (64 or more)• Open architecture for C/C++ orVisualBasic systems• Online productivity tools to analyze andimprove performance of the processIn a PC-based control system, a stan-dard operating system such as WindowsNT supports HMI and control softwarerunning on a PC platform, either areadily available commerical model or anindustrially hardened unit. PC architectureallows the system to seamlessly support avariety of third-party I/O, specialty motionand vision systems, and field networks.Programmable Automation ControllerA programmable automation controller isa compact controller that combines thefeatures and capabilities of a PC-basedcontrol system with that of a typical pro-grammable logic controller (PLC).This hybrid arose not only to solvecomplex applications with the speed andprocessing power of a PC-based system,but to do it on a platform capable ofwithstanding the environmental poundingthat PLCs have been subjected to formany years.Ideally, a PAC encompasses the followingfeatures:PLC Feel• Modular footprint• Industrial reliability• Wide array of I/O modulesand system configurationsPC Power• Large memory andfast processing• High-level data handlingand enterprise connectivity• Extensive communicationscapability, multiple protocols andfield networksPACs are most often used foradvanced machine control, processcontrol, data acquisition and equipmentmonitoring.Although each PAC vendor uses theirown development environment (IDE) andprogramming language, PAC networkingis typically based on IP and Ethernet.This class of controller provides more mem-ory capacity and processing power whichallows for better data processing capabili-ties, and connectivity to enterprise businesssystems from the plant floor.Additionally, PACs offer the benefit ofeasy integration for multi-domainsystems comprising Human MachineInterface (HMI), discrete control andprocess control.PLC vs. PAC vs. PC-based ControlVolume 13

The rest of your system will need to be compatible withnew components.Why this is important: Certain controller products may not becompatible with others. Making sure your existing products arecompatible with any new products you are researching will saveyou time and money. Check appropriate entry.2.EnvironmentalIssues____Codes/environmentalissues to consider____ No codes orenvironmentalissues to con-siderConsider any environmental issues that will affect your application(temperature, dust, vibration, codes specific to your facility, etc.).Why this is important: Certain environments may affect the opera-tion of a controller. For example, typical controllers have an oper-ating temperature of 0-55 degrees Celsius (32-130 degrees F). Ifyour application will include any extreme environmental condi-tions, or you have specific codes at your facility that must be met,you will need to either research products that meet those specifi-cations or design the installation to meet requirements. Checkappropriate entry.3.Discrete Devices_____ Total inputs:_____ AC_____ DC_____ Total outputs:_____ AC_____ DCDetermine how many discrete devices your system will have. Whichtypes (AC, DC, etc.) are needed?Why this is important: The number and type of devices your systemwill include is directly linked to the amount of I/O that will benecessary for your system. You will need to choose a controllerthat supports your I/O count requirements and has modules thatsupport your signal types.Enter quantities and type based on corre-sponding field devices.4.Analog Devices_____ Total inputs:____ Voltage____ Current____ Thermo____ RTD_____ Total outputs:____ Voltage____ CurrentDetermine how many analog devices your system will have.Which types (voltage, current, temperature, etc.) are needed?Why this is important: The number and type of devices your systemwill include is directly linked to the amount of I/O that will benecessary for your system. You will need to choose a controller thatsupports your I/O count requirements and has modules thatsupport your signal types. Enter quantities and type based on corre-sponding field devices.5.SpecialtyModules orFeatures(application-specific)_____ High speed counter_____ Positioning_____ Servo/stepper_____ BASIC programming_____ Real-time clock_____ Others (list)Determine whether your system will require any specialty features:Will your application require high-speed counting or positioning?What about a real-time clock or other specialty feature?Why this is important: Specialty functions are not necessarily avail-able in a controller CPU or in standard I/O modules.Understanding the special functions your system may perform willhelp you determine whether or not you will need to purchase addi-tional specialty modules. Check all features required.Use the worksheet on the following pages as a checklist of the things to consider when determiningprogrammable controller requirements. It lists the most important areas to consider when choosinga system, and provides space for recording determinations of your system needs.Table continued on the following page

How many devices will your system have (determines datamemory)? How large is your program, and what types of instructions will yourprogram include (determines program memory)? How fast a scan time doyou need?Why this is important: Data memory refers to the amount of memory neededfor dynamic data manipulation and storage in the system. For example,counter and timer instructions typically use data memory to store setpoints,current values, and other internal flags. If the application requires historicaldata retention, such as measured device values over a long period of time,the size of the data tables required may determine the CPU model youchoose. Program memory is the amount of memory needed to store thesequence of program instructions that have been selected to perform theapplication. Each type of instruction requires a specific amount of programmemory, typically defined in a programming manual. Applications that arebasically sequential in nature can rely on the I/O device rule of thumb to esti-mate program memory (five words of memory for each I/O device); complexapplications will be more difficult to judge.If scan time is important in your application, consider the CPU processorspeed as well as instruction execution speed. Some CPUs are faster atboolean logic but slower with data handling instructions.If special functions such as PID are required, the CPU you select may makethose functions easier to perform.For program memory required, follow this rule of thumb: 5 words of pro-gram memory for each discrete device and 25 words for each analogdevice. Check or calculate all requirements that apply.7.I/O Locations_______Local . . .only_______ Remote LocationsSpecific remote I/O protocolrequired? Which one?____________________Determine where your I/O will be located: Will your system require onlylocal I/O, or both local and remote I/O locations?Why this is important: If subsystems will be needed at long distances fromthe CPU, you will need a controller that supports remote I/O. You will alsohave to determine if the remote distances and speeds supported will beadequate for your application. Serial and Ethernet-based I/O hardwareare two typical choices available for most systems. This I/O may also bereferred to as distributed I/O, and may require a particular protocol, suchas Modbus.Enter number of physical locations needed, and if/what specific protocolmay be required.8.Commuications_____ Ethernet_____ PLC to PLC_____ Modbus RTU_____ ASCII (interface to serial devices)_____ OtherDetermine your communication requirements: Will your systembe communicating to other networks, systems or field devices?Why this is important: Communication ports (other than the programmingport) are not always included with a controller. Knowing your systemcommunication requirements will help you choose a CPU that supportsyour communication requirements, or additional communication modulesif necessary. Check any/all communications functions required.9.Programming_____Floatingpoint math_____Drumsequencer_____ PID loops_____ number of loops needed_____ Subroutines_____ Direct interrupts_____ Others (list)Determine your programming requirements: Does your application requireonly traditional programming instructions, or are special instructions neces-sary?Why this is important: Certain controllers may not support every type of instruc-tion. You will need to choose a model that supports all instructions that youmay need for a specific application. For example, built-in PID functions aremuch easier to use than writing your own code to perform closed-loopprocess control. Typical instructions such as timers, counters, etc. are availablein most controllers; note any other special instructions required here. Checkany/all programming functions required.

The powerhouse containsfive turbine generators with a combinedpower capacity of over 17 MW. The damand turbine control system receives datafrom power, flow, and level sensingdevices to perform monitoring and controlof the dam, generators, and associatedequipment.Lockhart Power contracted North ForkElectric in Crumpler, NC, to lend theirexpertise to a renovation of the conrtolsystem.The system consists of seven DirectLOGICDL205 micro-modular PLCs with built inPID functionality. Each of the five systemsfor generator control includes discrete andanalog I/O, and an Ethernet communica-tions module. The remaining two PLCs areconfigured in a master/slave arrangementand control the dam gates, located upriv-er from the powerhouse, via radiomodems. Operator interfaces include two6-inch color touch screen panels and aWindows NT-based PC running theLookoutDirect SCADA/HMI softwarepackage.In the automatic mode, the PLC can start,stop, and operate the generator, andcontrol startup and synchronization of theturbine. Changing the generator gateposition varies the flow of water to theturbine.The dam control system controls the eightcanal gates located at the dam, whichregulate the flow of water downstream tothe turbines.Semi cab sheetingproduction improvedITS, a design build firm in Columbus, Ohiospecializes in industrial automation. Thecompany was contacted by a division ofInternational Harvester responsible for themanufacturing of semi cabs. InternationalHarvester uses automated machines toplace aluminum rivets on sheeting that isattached to the frame of the semi cabs. Theoriginal CNC machines were becomingantiquated and needed to be upgraded.ITS chose a DL205 PLC as the new con-troller for the machines, along with discreteI/O and an H2-CTRIO high-speed countermodule that drives a dual axis servo. An H2-ECOM Ethernet Communications card linksthe machines back to an office for dataacquisition. ITS also added a 15-inch touchscreen for diagnostics.In the new system, an operator stampssheets of aluminum to welded frameworkwith a handful of hand rivets and thenplaces the product onto a dual axis servotable. After the operator selects one of fivedifferent parts programs, the machine willnavigate the panel under the head assem-bly, which is responsible for the drilling andriveting, with a tolerance of 1/10 of amillimeter. The panel is drilled and a rivet isinstalled and squeezed to approximately1200 PSI, producing a rivet consistencywithin .003 in. After completion of the panel(between 64 and 138 rivet locations), themachine will return to its home position andawait the next product.The solution increased productivity byapproximately 30% and provides an easyway to run and maintain the machines.DL06 PLC puts heaters tothe testPyromatics Automation Systems of CrystalLake, Il. was contracted by a customer todevelop a Life Cycle Test Station for itselectric heating elements.This test station needed a user-friendlygraphical interface to give operators theability to select multiple ramp/soak parame-ters, output voltages, temperature sensortypes, amperage ratings and total cyclecounts on tests for the cast-in electric heaterplatens. The system also needed to recordtemperature, volts, and current drawthroughout the test for use in quality reports.Also, a failure of the heater required a safeshutdown of the test while alerting the qual-ity department of the alarm condition.Pyromatics selected the cost-effectiveDirectLOGIC® DL06 PLC as the heart ofthe system because of its ability to control upto eight PID loops and the multiple expan-sion slots available for thermocouple cardsand analog input modules. It also controlstwo heaters, two chillers and an array ofpanel indicators, buttons, switches andrelays.A C-more 10-inch TFT touch-screen opera-tor interface was used to provide operatorswith the necessary interface to operate andmonitor the tests.The completed system allows users to quick-ly connect the heater to be tested, enter testparameters, and run the test. Trend chartson the C-more panel track test parametersand quickly identify potential issues such assudden drops in current or temperature.Alarm reporting and history are also auto-matically recorded, allowing the operator todetermine causes of failure. Data from thetest can be easily uploaded to a USB thumbdrive from the C-more panel. The data canthen be imported into the user’s choice ofword processor or spreadsheet.Application Briefs
