Installation2.6 Wiring2.6.1 Electrical ConsiderationsLine voltage wiringThis controller is considered “rack and panel mounted equipment” per EN61010-1,Safety Requirements for Electrical Equipment for Measurement, Control, and LaboratoryUse, Part 1: General Requirements. Conformity with 72/23/EEC, the Low VoltageDirective requires the user to provide adequate protection against a shock hazard. Theuser shall install this controller in an enclosure that limits OPERATOR access to the rearterminals.Mains Power SupplyThis equipment is suitable for connection to 90 to 264 Vac or to 24 Vac/dc 50/60 Hz,power supply mains. It is the user’s responsibility to provide a switch and non-time delay(North America), quick-acting, high breaking capacity, Type F (Europe), 1/2A, 250Vfuse(s), or circuit-breaker for 90-264 Vac applications; or 1 A, 125 V fuse or circuitbreaker for 24 Vac/dc applications, as part of the installation. The switch or circuitbreakershall be located in close proximity to the controller, within easy reach of theOPERATOR. The switch or circuit-breaker shall be marked as the disconnecting devicefor the controller.CAUTIONApplying 90-264 Vac to an instrument rated for 24 Vac/dc will severelydamage the instrument and is a fire and smoke hazard.When applying power to multiple instruments, make certain that sufficient current issupplied. Otherwise, the instruments may not start up normally due to the voltage dropcaused by the in-rush current.Controller GroundingPROTECTIVE BONDING (grounding) of this controller and the enclosure in which it isinstalled shall be in accordance with National and Local electrical codes. To minimizeelectrical noise and transients that may adversely affect the system, supplementarybonding of the controller enclosure to a local ground, using a No. 12 (4 mm 2 ) copperconductor, is recommended.Control/Alarm Circuit WiringThe insulation of wires connected to the Control/Alarm terminals shall be rated for thehighest voltage involved. Extra Low Voltage (ELV) wiring (input, current output, andlow voltage Control/Alarm circuits) shall be separated from HAZARDOUS LIVE (>30Vac, 42.4 Vpeak, or 60 Vdc) wiring per Permissible Wiring Bundling, Table 2-5.Electrical Noise PrecautionsElectrical noise is composed of unabated electrical signals which produce undesirableeffects in measurements and control circuits.4/07 UDC2500 Universal Digital Controller Product Manual 17

InstallationDigital equipment is especially sensitive to the effects of electrical noise. Your controllerhas built-in circuits to reduce the effect of electrical noise from various sources. If thereis a need to further reduce these effects:• Separate External Wiring—Separate connecting wires into bundles(See Permissible Wiring Bundling - Table 2-5) and route the individual bundlesthrough separate conduit metal trays.Use Suppression Devices—For additional noise protection, you may want to addsuppression devices at the external source. Appropriate suppression devices arecommercially available.ATTENTIONFor additional noise information, refer to document number 51-52-05-01, How to Apply DigitalInstrumentation in Severe Electrical Noise Environments.Permissible Wiring BundlingTable 2-5 Permissible Wiring BundlingBundle No.Wire Functions1 • Line power wiring• Earth ground wiring• Line voltage control relay output wiring• Line voltage alarm wiring2 Analog signal wire, such as:• Input signal wire (thermocouple, 4 to 20 mA, etc.)• 4-20 mA output signal wiringDigital input signals3 • Low voltage alarm relay output wiring• Low voltage wiring to solid state type control circuits• Low voltage wiring to open collector type control circuits18 UDC2500 Universal Digital Controller Product Manual 4/07

The model number of the controller is on theoutside of the case.Universal Output Functionality and RestrictionsInstruments with multiple outputs can be configured to perform a variety of output typesand alarms. For example, an instrument with one current output and two relays can beconfigured to provide any one of the following:1) Current Simplex with two alarm relays2) Current Duplex 100% with two alarm relays3) Time Simplex with one alarm relay4) Time Duplex with no alarm relays5) Three Position Step Control with no alarm relaysThese selections may all be made via the keyboard and by wiring to the appropriateoutput terminals; there are no internal jumpers or switches to change. This flexibilityallows a customer to stock a single instrument which is able to handle a variety ofapplications.Table 2-6 shows what control types and alarms are available based upon the installedoutputs. In this table, when Duplex Control and Reverse Action are configured:Output 1 is HEAT and Output 2 is COOL.In Table 2-6 when Three Position Step Control is configured:Output 1 is OPEN and Output 2 is CLOSE.In Table 2-6 the Output 1/2 option Single Relay can be any of the following selections:Electro-Mechanical Relay, Solid-State Relay or Open Collector Output.4/07 UDC2500 Universal Digital Controller Product Manual 19

Configuration3.4 Tuning Set Up GroupIntroductionTuning consists of establishing the appropriate values for the tuning constants you areusing so that your controller responds correctly to changes in process variable andsetpoint. You can start with predetermined values but you will have to watch the systemto see how to modify them. The Accutune feature automatically selects Gain, Rate, andReset on demand.ATTENTIONBecause this group contains functions that have to do with security and lockout, we recommendthat you configure this group last, after all other configuration data has been loaded.Function PromptsTable 3-4 TUNING Group (Numeric Code 100) Function PromptsFunction PromptLower DisplayEnglishNumericCodeSelection or Range of SettingUpper DisplayEnglishNumericCodeParameterDefinitionPB or GAIN 101 PB = 0.1 to 1000 %Gain = 0.01 to1000PROPORTIONAL BAND (simplex) is thepercent of the range of the measuredvariable for which a proportional controllerwill produce a 100 % change in its output.GAIN is the ratio of output change (%) overthe measured variable change (%) thatcaused it.G = 100%PB%where PB is the proportional band (in %)If the PB is 20 %, then the Gain is 5. And, atthose settings, a 3 % change in the errorsignal (SP-PV) will result in a 15 % change inthe controller's output due to proportionalaction.

Configuration3.6 Accutune Set Up GroupIntroductionAccutune III automatically calculates GAIN, RATE, and RESET TIME (PID) tuningconstants for your control loop. When initiated on demand, the Accutune algorithmmeasures a process step response and automatically generates the PID tuning constantsneeded for no overshoot on your process.Fuzzy, Fuzzy Overshoot Suppression: When enabled, this configuration will suppress oreliminate any overshoot that may occur as a result of the existing tuning parameters, asthe PV approaches the setpoint.Tune, Demand Tuning: The tuning process is initiated through the operator interface keysor via a digital input (if configured). The algorithm then calculates new tuning parametersand enters them in the tuning group. Tune will operate with PIDA, PIDB, PD+MR andThree Position Step Control algorithms.SP, SP Tuning: SP tuning continuously adjusts the PID parameters in response tosetpoint changes. You can select tuning on minimum setpoint changes of5 % up to 15 % span. Perform SP tuning after you have configured the controller. SPTuning does not operate with the Three Position Step Control algorithm.Simplex Tuning is used when a Simplex Control Algorithm is configured and uses thecurrent SP value and alters the output over the Output Limit Range.Duplex Tuning is used when a Duplex Control Algorithm is configured. To perform aDuplex Tune, Two Local Setpoints must be configured per the Control Group in Section3.11.4/07 UDC2500 Universal Digital Controller Product Manual 43

Configuration3.7 Algorithm Set Up GroupIntroductionThis data deals with various algorithms in the controller and Timer functions.The Timer section allows you to configure a time-out period and to select the timer startby either the keyboard (RUN/HOLD key) or Alarm 2. An optional digital input can also beconfigured to the start the timer. The timer display is selectable as either “timeremaining” (see TREM) or “elapsed time” (see ET).Alarm 1 is activated at the end of the time-out period. When the timer is enabled, it hasexclusive control of the alarm 1 relay—any previous alarm 1 configuration is ignored. Attime-out, the timer is ready to be activated again by whatever action has been configured.Function PromptsTable 3-7 ALGOR Group (Numeric Code 400) Function PromptsFunction PromptLower DisplayEnglishNumericCodeSelection or Range of SettingUpper DisplayEnglishNumericCodeParameterDefinitionCTRALG 401The CONTROL ALGORITHM lets you selectthe type of control that is best for yourprocess.ONOF 0ON/OFF is the simplest control type. Theoutput can be either ON (100 %) or OFF (0%). The Process Variable (PV) is comparedwith the setpoint (SP) to determine the signof the error (ERROR = PV–SP). TheON/OFF algorithm operates on the sign ofthe error signal.In Direct Acting Control, when the errorsignal is positive, the output is 100 %; andwhen the error signal is negative, the outputis 0 %. If the control action is reverse, theopposite is true. An adjustable overlap(Hysteresis Band) is provided between theon and off states.ATTENTION Other prompts affected:OUTHYS46 UDC2500 Universal Digital Controller Product Manual 4/07

BothDeadband and Hysteresis are separatelyadjustable. With no relay action the controllerwill read 50 %.ATTENTION Other prompts affected:OUTHYS and DEADBDPID A is normally used for three-modecontrol. This means that the output can beadjusted somewhere between 100 % and 0%. It applies all three control actions—Proportional (P), Integral (I), and Derivative(D)—to the error signal.Proportional (Gain)—Regulates thecontroller’s output in proportion to the errorsignal (the difference between ProcessVariable and Setpoint).Integral (Reset)—Regulates the controller’soutput to the size of the error and the timethe error has existed. (The amount ofcorrective action depends on the value ofproportional Gain.)Derivative (Rate)—Regulates thecontroller’s output in proportion to the rate ofchange of the error. (The amount ofcorrective action depends on the value ofproportional Gain.)PID B—Unlike the PID A equation, thecontroller gives only an integral response toa setpoint change, with no effect on theoutput due to the gain or rate action, and itgives full response to PV changes.Otherwise controller action is as describedfor the PID A equation.

The deadband is adjustable inthe same manner as the duplex outputalgorithm.The Three Position Step Control algorithmprovides an output display (OUT) which is anestimated motor position, since the motor isnot using any slidewire feedback. Althoughthis output indication is only anapproximation, it is “corrected” each time thecontroller drives the motor to one of its stops(0 % or 100 %). It avoids all the controlproblems associated with the feedbackslidewire (wear, dirt, noise). When operatingin this algorithm, the estimated OUT displayis shown to the nearest percent (i.e., nodecimal).Refer to the Operation section for motorposition displays.As a customer configurable option, when asecond input board is installed, the motorslidewire can be connected to the controller.48 UDC2500 Universal Digital Controller Product Manual 4/07

Configuration3.14 Alarms Set Up GroupIntroductionAn alarm is an indication that an event that you have configured (for example—ProcessVariable) has exceeded one or more alarm limits. There are two alarms available. Eachalarm has two setpoints. You can configure each of these two setpoints to alarm onvarious controller parameters.There are two alarm output selections, High and Low. You can configure each setpoint toalarm either High or Low. These are called single alarms.You can also configure the two setpoints to alarm on the same event and to alarm bothhigh and low. A single adjustable Hysteresis of 0 % to 100 % is configurable for thealarm setpoint.See Table 2-3 in the Installation section for Alarm relay contact information.The prompts for the Alarm Outputs appear whether or not the alarm relays are physicallypresent. This allows the Alarm status to be shown on the display and/or sent viacommunications to a host computer.Function PromptsTable 3-15 ALARMS Group (Numeric Code 1100) Function PromptsFunction PromptLower DisplayEnglishNumericCodeA1S1TY 1101Selection or Range of SettingUpper DisplayEnglishNumericCodeParameterDefinitionALARM 1 SETPOINT 1 TYPE—Select whatyou want Setpoint 1 of Alarm 1 to represent.It can represent the Process Variable,Deviation, Input 1, Input 2, Output, and if youhave a model with communications, you canconfigure the controller to alarm on SHED.

Alarm 1 is not available if the Timeris enabled because Alarm 1 is dedicated toTimer output.NOTE 3. This Deviation Alarm is based upondeviation from the 2nd Local Setpoint orRemote SP regardless of whichever SP isactive.NOTE 4. Loop Break monitors the controlloop to determine if it is working. Whenenabled, the control output is checkedagainst the minimum and maximum outputlimit settings. When the output reaches oneof these limits, a timer begins. If the timerexpires and the output has not caused thePV to move by a pre-determined amount,then the alarm activates, thus signalling thatthe loop is broken. The loop break timervalue must be configured by the operator asthe AxSx VAL entry. This value is inseconds with a range of 0 to 3600 seconds.A setting of 0 is equivalent to aninstantaneous loop break when the outputreaches one of its limit values.The amount of PV Movement required isdetermined by the “UNITS” setting in theDisplay Setup Group. For the Degrees Fconfiguration, the PV must move by 3° in thedesired direction in the time allowed. For theDegrees C configuration, the PV must moveby 2° in the desired direction in the timeallowed. For the “NONE” selection, the PVmust move 1% of the PV range in the timeallowed.Loop Break alarms do not have aHIGH/LOW State configuration, they arealways assumed to be a HIGH state alarm.4/07 UDC2500 Universal Digital Controller Product Manual 77

Configuration3.16 P.I.E. Tool Ethernet and Email Configuration ScreensIntroductionThese screens only appear in instruments that have Ethernet Communications. Ethernetand Email parameters can only be configured via the Process Instrument Explorer (P.I.E.Tool ® ). The figures in this section show screen-shots of the Configuration Screens fromthe PC version of the P.I.E. Tool ® . Pocket PC Configuration Screens are generallysimilar in format but smaller.Ethernet Configuration ScreenThis controller is shipped from the factory with the IP Address set to 10.0.0.2, the SubnetMask set to 255.255.255.0 and the Default Gateway set to 0.0.0.0. Consult yourInformation Technologies (IT) representative as to how these should be configured foryour installation. The MAC address is printed on the product label located on theinstrument’s case.These settings can be changed via the Ethernet Configuration Screen as shown in Figure3-1.See Section 4.23 – Configuring your Ethernet Connection for more information.Figure 3-1 Ethernet Configuration Screen84 UDC2500 Universal Digital Controller Product Manual 4/07

ConfigurationWARNINGAfter you change the IP Address, you will no longer be able to communicate with the instrumentvia Ethernet until you change the P.I.E. Tool’s IP Address setting in the PC COMM SETUPsection to match the setting that is now in your controller. See Section 4.23 – Configuring yourEthernet Connection for more information.Email Configuration ScreenThis controller may be configured to support sending an Email when an alarm occurs.Emails are sent only when the selected alarm transitions from the OFF to the ON state.Figure 3-2 Email Configuration ScreenThis controller cannot receive Emails, so it is suggested that you configure the FromEmail: window with a non-Email style address that will make it easy for you todetermine which controller sent the Email. For Email technical reasons, the entry in theFrom Email: window cannot have spaces. See Figure 3-2.If you do not know your SMTP IP Address for outgoing Email, then contact yourInformation Technologies (IT) representative. If your PC is on the same LAN that will beused by the controller and which also connects to the Email server, then the SMTP IPAddress may generally be found by opening a DOS shell and typing:ping smtp.[your domain name and extension], i.e., ping smtp.your_isp.com4/07 UDC2500 Universal Digital Controller Product Manual 85

ConfigurationThe content of the Emails sent by this controller contains the Alarm that triggered theEmail, its settings and the current value (if applicable) of the monitored variable. Forexample, the content of an Email triggered by Alarm 1 Setpoint 1 that is configured tomonitor Input 1 would look something like this:Name: Alarm 1 SP1, Type: INPUT1, Event: HIGH/END, Value = 500.00,Actual = 712.69The content of an Email triggered by Alarm 2 Setpoint 1 that is configured to monitorDigital Input 1 would look something like this:Name: Alarm 2 SP1, Type: DIG IN1, Event: HIGH/END, Value = 0.00,Actual = 0.00ATTENTIONEmail will always be time-stamped with the date that the Ethernet Software in the instrumentwas last modified.If the SMTP address on your network is changed, such as can happen when a server isreplaced, then you must reconfigure the Email SMTP IP address in this instrument to match thenew IP address.86 UDC2500 Universal Digital Controller Product Manual 4/07

However, knowledgeof a security code number (0 to 9999) may be required to change from one level oflockout to another. When a controller leaves the factory, it has a security code of 0 whichpermits changing from one lockout level to another without entering any other codenumber.If you require the use of a security code, select a number from 0001 to 9999 and enter itwhen the lockout level is configured as NONE. Thereafter, that selected number must beused to change the lockout level from something other than NONE.ATTENTION Write the number on the Configuration Record Sheet in the configurationsection so you will have a permanent record.90 UDC2500 Universal Digital Controller Product Manual 4/07

Monitoring and Operating the Controller4.8 Control ModesATTENTIONAfter changing a Local Setpoint value, if no other key is pressed, it then takes a minimum of thirty (30)seconds elapsed time before the new value is stored in non-volatile memory. If controller power isremoved before this time, the new setpoint value is lost and the previous setpoint value is used atpower-up. If, after changing the LSP value, another key is pressed, then the value is storedimmediately.4.8.1 Mode DefinitionsTable 4-7 Control Mode DefinitionsControl ModeAUTOMATIC withLOCALSETPOINTAUTOMATIC withREMOTESETPOINT(optional)MANUAL(optional)DefinitionIn automatic local mode, the controller operates from the local setpoints andautomatically adjusts the output to maintain the PV at the desired value.In this mode you can adjust the setpoint.See Subsection 4.9 - Setpoints.In automatic remote mode, the controller operates from the setpoint measured at theremote setpoint input. Adjustments are available to ratio this input and add aconstant bias before it is applied to the control equation.See Subsection 3.9 or 3.10, Input 1 or Input 2.In the manual mode, the operator directly controls the controller output level. Theprocess variable and the percent output are displayed. The configured High andLow Output Limits are disregarded and the operator can change the output value,using the increment and decrement keys, to the limits allowed by the output type(0 % to 100 % for a time proportioning output or –5 % to 105 % for a current output).Manual Mode not available with Single Display model.100 UDC2500 Universal Digital Controller Product Manual 4/07

Monitoring and Operating the Controller4.11 Accutune IIIIntroductionAccutune III (TUNE) may be used for self-regulating and single integrating processes.This autotuning method is initiated on-demand, typically at initial start-up.There are no other requirements necessary, such as prior knowledge to the processdynamics or initial or post tune process line-out to setpoint or manual output.Also, the setpoint value is not required to change in order to initiate the tuning process,but the controller must be in the Automatic mode to start tuning. The process need not bein a static (lined out) state and may be dynamic (changing with a steady output).Configuration checkMake sure:• TUNE has been enabled see to Subsection 3.6 - Accutune Set Up Group for details.Tuning indicatorsOperation“TUNE” will flash in the upper display until tuning is completed.The “TUNE” (Accutune II) algorithm provides user-friendly, on-demand tuning in thiscontroller. No knowledge of the process is required at start-up. The operator simplyinitiates the tuning while in the automatic mode.Once Accutune III has been enabled in the TUNE setup group, either “SLOW” or“FAST” tuning may be used. Which one is used is selected via the lower display duringnormal operation.For the SLOW selection, the controller calculates conservative tuning constants with theobjective of minimizing overshoot. If the controller determines that the process hasappreciable dead time, it will automatically default to use Dahlin Tuning, which producesvery conservative tuning constants. The SLOW selection may be useful for TPSCapplications, as it reduces any “hunt” problems for the motor.For the FAST selection, the controller calculates aggressive tuning constants with theobjective of producing quarter damped response. Depending upon the process, thisselection will usually result in some overshoot. For this reason, it may be desireable toenable the FUZZY tune selection. See Section 4.12. When Fuzzy tune is enabled, it willwork to suppress or eliminate any overshoot that may occur as a result of the calculatedtuning parameters as the PV approaches the setpoint.The TUNE process will cycle the controller’s output two full cycles between the low andhigh output limits while allowing only a very small Process Variable change above andbelow the SP during each cycle. “TUNE” flashes in the upper display until tuning iscompleted.104 UDC2500 Universal Digital Controller Product Manual 4/07

Monitoring and Operating the ControllerAt the end of the tuning process, the controller immediately calculates the tuningconstants and enters them into the Tuning group, and begins PID control with the correcttuning parameters. This works with any process, including integrating type processes,and allows retuning at a fixed setpoint.4.11.1 Tune for Simplex OutputsAfter “TUNE” has been enabled, you can start Accutune as shown in Table 4-11.Table 4-11 Procedure for Starting “TUNE”Step Operation Press Result1 Configure LSP1LowerDisplayUntil SP (Local Setpoint 1) showsin the lower display.2 orUntil LSP1 is to the desired value.3 Switch to“Automatic” Mode4 Show TuningPromptM-AResetLowerDisplayUntil the “A” indicator is lighted (oncontrollers with Manual option).Until “NoTUNE” is shown on lowerdisplay.5 Initiate Tuning Select “DoSLOW” or “DoFAST” inlower display.6 Tuning in operation LowerDisplayUpper display will flash “TUNE” aslong as ACCUTUNE process isoperating. When processcompletes, tuning parameters arecalculated and lower display willshow “NoTune” prompt.ATTENTIONThe Accutune process may be aborted at any time by changing the lower display back to “NoTUNE” orby switching the controller into Manual Mode.4.11.2 Tune for Duplex (Heat/Cool)Accutune for applications using Duplex (Heat/Cool) control.The controller must be configured to have two local setpoints unless Blended Tuning isdesired (see below). See Subsection 3.11- Control Set Up Group for details onconfiguring two local setpoints. During tuning, the Accutune III process assumes thatLocal Setpoint 1 will cause a Heating demand (output above 50%), and the tuningparameters calculated for that setpoint are automatically entered as PID SET 1. Likewise,Accutune III assumes that Local Setpoint 2 will cause a Cooling demand (output lessthan 50%), and the tuning parameters calculated for that setpoint are automaticallyentered as PID SET 2.4/07 UDC2500 Universal Digital Controller Product Manual 105

This is the preferred selection forHeat/Cool applications which use a highly insulated chamber (a chamber which will loseheat very slowly unless a cooling device is applied). Only one local setpoint (LSP 1) isneeded for this selection.106 UDC2500 Universal Digital Controller Product Manual 4/07

Monitoring and Operating the ControllerThis selection results in performance tuning over the full range utilizing both Heat andCool outputs to acquire blended tune values that are then applied to both Heat and Cooltuning parameters. Both PID sets are set to the same values.Table 4-13 Procedure for Using BLENDED TUNE at Start-up for Duplex ControlStep Operation Press Result1 Configure LSP1LowerDisplayUntil SP (Local Setpoint 1) showsin the lower display.2 or3 Switch to“Automatic” ModeM-AResetUntil the Setpoint is to the desiredvalue.Until the “A” indicator is lighted (oncontrollers with Manual option).4 Show TuningPromptLowerDisplayUntil “NoTUNE” is shown on lowerdisplay.5 Initiate Tuning Select “DoSLOW” or “DoFAST” inlower display.6 Tuning in operation LowerDisplayUpper display will flash “TUNE” aslong as ACCUTUNE process isoperating.

Monitoring and Operating the ControllerCompleting AccutuneWhen Accutune is complete, the calculated tuning parameters are stored in their propermemory location and can be viewed in the TUNING Set up Group, and the controllerwill control at the local setpoint using these newly calculated tuning constants.4.12 Fuzzy Overshoot SuppressionIntroductionFuzzy Overshoot Suppression minimizes Process Variable overshoot following a setpointchange or a process disturbance. This is especially useful in processes which experienceload changes or where even a small overshoot beyond the setpoint may result in damageor lost product.How it worksThe fuzzy logic observes the speed and direction of the PV signal as it approaches thesetpoint and temporarily modifies the internal controller response action as necessary toavoid an overshoot. There is no change to the PID algorithm, and the fuzzy logic doesnot alter the PID tuning parameters. This feature can be independently Enabled orDisabled as required by the application to work with “TUNE” (On-Demand) AccutuneIII tuning algorithm.ConfigurationTo configure this item, refer to Section 3 - Configuration:Set Up Group “ATUNE”Function Prompt “FUZZY”Select “ENAB”(enable) or “DIS” (disable) - Use or .4.13 Using Two Sets of Tuning ConstantsIntroductionYou can use two sets of tuning constants for single output types and choose the way theyare to be switched.

Monitoring and Operating the Controller4.21 Setpoint Ramp/Soak ProgrammingIntroductionThe term “programming” is used here to identify the process for selecting and enteringthe individual ramp and soak segment data needed to generate the required setpointversus time profile (also called a program).A segment is a ramp or soak function which together make up a setpoint program.Setpoint Ramp/Soak Programming lets you configure six ramp and six soak segments tobe stored for use as one program or several small programs. You designate the beginningand end segments to determine where the program is to start and stop.Review program data and configurationWhile the procedure for programming is straightforward, and aided by prompts, wesuggest you read “Program Contents”. Table 4-25 lists the program contents and anexplanation of each to aid you in configuration. Then refer to Subsection 3.5 –Configuration to do the setpoint program.Make sure SPRATE and SPRAMP are disabled.Fill out the worksheetRefer to the example in Figure 4-3 and draw a Ramp/Soak Profile on the worksheetprovided (Figure 4-4) and fill in the information for each segment. This will give you arecord of how the program was developed.OperationRefer to Table 4-26 Run/Monitor the program.Program ContentsTable 4-25 lists all the program contents and a description of each.Table 4-25 Program ContentsContentsRamp time or ratesegmentsDefinitionA ramp segment is the time or rate of change it takes to change the setpointto the next setpoint value in the program.• Ramps are odd number segments. Segment #1 will be the initial ramp time.• Ramp time is determined in either:TIME* - Hours:Minutes Range = 0-99 hr.:59 min.orEU-M* - Degrees/Minute Range = 0 to 999EU-H* - Degrees/Hour*The selection of time or rate is made at prompt “RP UNIT”- Set this prompt before entering any Ramp information.118 UDC2500 Universal Digital Controller Product Manual 4/07

Monitoring and Operating the ControllerContentsDefinitionATTENTION Entering “0” will imply an immediate step change in setpoint tothe next soak.Ramp unitThe ramp unit selection determines the engineering units for the rampsegments.The selections are:• TIME = Hours:Minutes (XX:XX) Range: 0-99 hr.:0-59 min• EU-H = Degrees/Hour OR EU-M = Degrees/Minute (Range – 0-999)Soak segmentsStart segmentnumberA soak segment is a combination of soak setpoint (value) and a soak duration(time).• Soaks are even number segments.• Segment 2 will be the initial soak value and soak time.• The soak setpoint range value must be within the setpoint high and lowrange limits in engineering units.• Soak time is the duration of the soak and is determined in:TIME - Hours:MinutesRange = 0-99 hr.:59 min.The start segment number designates the number of the first segment.Range = 1 to 11End segment number The end segment number designates the number of the last segment, it mustbe a soak segment (even number). Range = 2 to 12Recycle numberGuaranteed soakPV StartThe recycle number allows the program to recycle a specified number oftimes from beginning to end. Range = 0 to 99All soak segments can have a deviation value of from 0 to ± 99 (specified bySOK DEV) which guarantees the value for that segment.Guaranteed soak deviation values >0 guarantee that the soak segment’sprocess variable is within the ± deviation for the configured soak time.Whenever the ± deviation is exceeded, soak timing is frozen.There are no guaranteed soaks whenever the deviation value is configured to0, (that is, soak segments start timing soak duration as soon as the soaksetpoint is first reached, regardless of where the process variable remainsrelative to the soak segment).The soak deviation value is the number in engineering units, above or belowthe setpoint, outside of which the timer halts. The range is 0 to ± 99.The decimal location corresponds to input 1 decimal selection.This function determines whether LSP1 or PV is used as the setpoint whenthe program is initially changed from HOLD to RUN.The selections are:DISABL = When the program is initially changed from HOLD to RUN thepresent LSP1 value is captured as the default setpoint. If theprogram is terminated or the power cycled before the program hascompleted, the LSP1 is used as the control setpoint. Thebeginning segment uses this value as the initial ramp setpoint.4/07 UDC2500 Universal Digital Controller Product Manual 119

If the program is terminated beforecompletion, the setpoint value will revert back to the PV valuecaptured at the initial HOLD to RUN transition. If the power iscycled before program completion, upon power-up the setpoint isset to the PV value at power-up and when the program is restartedthat setpoint value is used initially.Program stateProgram terminationstateReset Program toBeginningThe program state selection determines the program state after completion.The selections are:• DIS = program is disabled (so program value changed to DIS)• HOLD = program on holdThe program termination state function determines the status of the controllerupon completion of the program.The selections are:• LAST = controls to last setpoint• FSAF = manual mode and failsafe output.When enabled, this selection allows you to reset the program to the beginningfrom the keyboard.Ramp/soak profile exampleBefore you perform the actual configuration, we recommend that you draw a Ramp/Soakprofile in the space provided on the “Program Record Sheet” (Figure 4-4) and fill in theassociated information.

Monitoring and Operating the ControllerConfiguring the Controller via Ethernet CommunicationsWARNINGConfiguring the Controller via Ethernet Communications requires that you change your PC’s IPsettings. If you have never done this before, then it is strongly recommended that you consultwith your Information Technologies (IT) representative before proceeding.First, write down the current Local Area Network (LAN) configuration values for yourPC for its IP Address, Subnet Mask and Default Gateway settings. Put these someplacethat you can find them later.Connecting to the Ethernet Port in the Controller requires that you have either anEthernet crossover cable or a MDI-compliant Switch or Hub available with a straightthroughcable. The crossover cable can be used to directly connect your PC to theController while the Switch or Hub can be used to connect your PC and Controller to theHub or Switch via straight-through cables.Once you have made an Ethernet connection between your PC and the controller, thenchange the Local Area Network (LAN) settings on your PC to be as follows:IP Address: 10.0.0.3Subnet Mask: 255.255.255.0Default Gateway: 10.0.0.1Now open your P.I.E. Tool ® program and select PC Comm Setup and select Ethernet asyour Communication Type as shown in Figure 4-14.Figure 4-14 Ethernet Communications Type Selection4/07 UDC2500 Universal Digital Controller Product Manual 133

Output Calibration6.2 Current Output CalibrationIntroductionCalibrate the controller so that the output provides the proper amount of current over thedesired range. The controller can provide an output current range of from 0 to 21milliamperes and is usually calibrated at 4 mA for 0 % of output and 20 mA for 100 % ofoutput, or any other values between 0 mA and 21 mA. It is not necessary to re-calibratethe controller in order to change from 4 to 20 mA operation over to 0 to 20 mA operation,a simple configuration change is all that is required. See the CO RANGE configurationin Sub-section 3.8 for details.Equipment NeededYou will need a standard shop type milliammeter, with whatever accuracy is required,capable of measuring 0 to 20 milliamps.Calibrator ConnectionsRefer to Figure 6-1 and wire the controller according to the procedure given in Table 6-1.StepTable 6-1 Set Up Wiring Procedure for Current OutputAction1 Apply power and allow the controller to warm up 30 minutes before you calibrate.2 Set LOCK in the Tuning Set Up group to NONE.3 Tag and disconnect the field wiring, at the rear of the controller, from terminals21 (–) and 19 (+).

Modbus Read, Write and Override Parameters plus Exception Codes10 Modbus Read, Write and Override Parametersplus Exception Codes10.1 OverviewIntroductionThis section contains information concerning Reading, Writing, and Overridingparameters in this instrument. There are two types of parameters:• Data Transfer—These parameters include reading control data, option status, andreading or changing setpoints.• Configuration Data—All the configuration data is listed in the order in which itappears in the controller.Each type of parameter has the identifying codes listed with it.What's in this section?The following topics are covered in this section.TOPICSee Page10.1 Overview 18910.2 Reading Control Data 19010.3 Read Options Status 19110.4 Miscellaneous Read Onlys 19210.5 Setpoints 19310.6 Using a Computer Setpoint (Overriding Controller Setpoint) 19410.7 Configuration Parameters 19510.8 Modbus RTU Exception Codes 218General InformationNon-volatile Memory Retention• This controller uses non-volatile memory to store configuration data. Thesememories are guaranteed to retain data for a minimum of ten years as long as the datais not written and erased more than 10,000 times. In order not to exceed this number,it is strongly recommended that configurations which change rapidly such asComputer Setpoint use the Override feature which does not affect non-volatilememory.4/07 UDC2500 Universal Digital Controller Product Manual 189

Modbus Read, Write and Override Parameters plus Exception CodesAnalog Parameters• Whenever analog register addresses 0001 through 0074 (those that can be changedvia communications) are changed, a Write cycle occurs after receipt of the messageand the response is returned.Override Parameters• Override analog register address 007D (computer setpoint) is not stored in nonvolatilememory. It can be changed as frequently as desired with no effect on nonvolatilememory retentivity, but the controller must remain in the slave mode.Digital Parameters• Whenever digital configuration register addresses 0080 through 00FA are updated viacommunications, the non-volatile memory is updated as soon as the message isreceived.Communications Transfer Rates• Reads minimum 20mS and writes minimum 200mSSupported Function Codes• IR port 20 and 21• RS485 and Ethernet ports 1,2,3,4,6,16,17,20,21Communications Modes of Operation• When the Shed Timer is enabled and a write or override occurs the controller willenter Slave Mode. The keypad is locked from the operator. The purpose of this modeis that if communications is lost and the shed timer times out then the controller willenter a known state of operation. The configuration of the “Shed Mode and Output”and Shed Setpoint Recall are used to configure the controller’s shed state. While inSlave Mode pushing the MAN/AUTO key enters Emergency Manual mode. Thelocal operator then has control of the output. The controller is in Monitor Mode if theShed timer is disabled.10.2 Reading Control DataOverviewThe following control data can be read from this instrument:• Input 1• Input 2• PV, SP, OutputRegister AddressesUse the identifying codes listed in Table 10-1 to read the specific items.A Write request for these codes will result in an Error message.190 UDC2500 Universal Digital Controller Product Manual 4/07

Modbus Read, Write and Override Parameters plus Exception Codes10.8 Modbus RTU Exception CodesIntroductionWhen a master device sends a query to a slave device it expects a normal response. Oneof four possible events can occur from the master’s query:• Slave device receives the query without a communication error and can handle thequery normally.It returns a normal response.• Slave does not receive the query due to a communication error.No response is returned. The master program will eventually process a time-outcondition for the query.• Slave receives the query but detects a communication error (parity, LRC or CRC).No response is returned. The master program will eventually process a time-outcondition for the query.• Slave receives the query without a communication error but cannot handle it (i.e.,request is to a non-existent coil or register).The slave will return with an exception response informing the master of the nature ofthe error (Illegal Data Address.)The exception response message has two fields that differentiate it from a normalresponse:Function Code Field:In a normal response, the slave echoes the function code of the original query in thefunction code field of the response. All function codes have a most-significant bit(MSB) of 0 (their values are below 80 hex). In an exception response, the slave setsthe MSB of the function code to 1. This makes the function code value in anexception response exactly 80 hex higher than the value would be for a normalresponse.With the function code’s MSB set, the master’s application program can recognizethe exception response and can examine the data field for the exception code.Data Field:In a normal response, the slave may return data or statistics in the data field. In anexception response, the slave returns an exception code in the data field. This definesthe slave condition that caused the exception.218 UDC2500 Universal Digital Controller Product Manual 4/07

Ethernet TCP/IP11 Ethernet TCP/IP11.1 OverviewEthernet parameters can only be configured via the Process Instrument Explorersoftware.Ethernet IP Address is 10.0.0.2 as shipped from the Factory.The MAC address is printed on the case label of each instrument.When constructing a network, it is recommended that a Switch be used to connect UDCsto a LAN rather than using a Hub. This is because a Switch passes only those messagesfor IP addresses that are connected to the Switch while a Hub passes all message traffic.Using a Switch thus improves the overall throughput of the traffic to and from the UDCs.220 UDC2500 Universal Digital Controller Product Manual 4/07
