HIMSmart HART Loop


The HIMThe Moore Industries HIM HART Interface Moduleunlocks the full potential of new and in-place HARTmultivariable transmitters, valves, meters and othersmart instruments.

Converts HART to 4-20mA SignalsThe HIM allows up to three additional analog processvariable measurements from a multivariable transmit-ter or valve with no additional process penetrations.Installed transparently across the 4-20mA instrumentloop, the HIM reads the HART digital process data thatrides on the loop wires. It converts the digital informa-tion for up to three isolated analog (4-20mA) processsignals that are readily accepted by in-place controlsystems, such as a DCS or PLC.

Provides Process and Diagnostic AlarmsRelay alarm trips (optional) can be individually user-seteither to trip when unwanted high/low process condi-tions occur, or provide a diagnostic health warning toalert of loop or instrument fault conditions.

Takes Advantage of Legacy InstrumentsThe device lets you leave existing smart HART trans-mitters and valves in place, yet still take advantage ofall the information they have to offer.

Works with every Smart HART DeviceThe instrument can be programmed in minutes to inter-face with every HART-compatible monitoring and con-trol device.

Table 2. Assembling the Necessary EquipmentConfiguring the HIMOne of the benefits of the HIM is that there are nointernal or external controls to adjust or settings tochange. All operating parameters are set using the PCConfiguration software.

Once these software settings are made, they aredownloaded to the monitor in the form of a ConfigurationFile and stored in the unit’s non-volatile memory. Youcan choose to save a backup copy of the file on yourPC hard drive or external media. The HIM communi-cates with the PC through a proprietary communica-tions cable to the PC’s serial (COM) port.

Begin by installing the PC Configuration Software.

Installing the PC Configuration SoftwareRefer to Table 2 for the equipment needed.

1. Insert the Moore Industries Interface SolutionPC Configuration Software CD into the CD driveof the PC. Access the CD and open the HIMPC Configuration Software folder.

2. Double-click the installation program located inthe folder. Follow the prompts to correctlyinstall the program.

Once the Configuration Program is installed on the PC,the unit can be connected either into the loop or to testequipment to simulate input and monitor output. Withthe PC program, the user can then view and/or changeits operating parameters. To begin the process, connectthe HIM either into the loop (see Installing the HIM intothe Loop) or into a configuration setup (see BenchChecking the HIM).


HIMSmart HART Loop


Installing the HIMThere are two methods for connecting the HIM forconfiguration. The recommended method requires youto install the instrument into the loop before it isconfigured. The secondary method allows you to benchcheck the HIM by attaching it to test equipment thatwill simulate the input and monitor the output.

Installing the HIM into the LoopInstallation consists of physically mounting the unit,grounding the instrument, and completing the electricalconnections. To install the HIM into the loop forconfiguration, use the equipment in Table 2 to hookupthe HIM into the loop as shown in Figure 3 (withoutusing the HIM to power a transmitter) or Figure 4 (usingthe TX terminal to power a transmitter). If you need acomplete terminal description, refer to Table 1.

MountingThe HIM is designed to snap easily onto 32mm, G-type(EN50035) or 35mm Top Hat (EN50022) DIN rails.

Electrical ConnectionsAfter mounting, you are ready to connect the HIM tothe loop. Each unit comes equipped with a transmitterexcitation terminal which allows it to supply power tothe monitored HART instrument, if necessary. Figures2 and 3 show the connection diagrams for an HIM withor without using the transmitter excitation current.

CE ConformityInstallation of any Moore Industries products that carrythe CE certification (Commission Electrotechnique)must adhere to the guidelines in Installing the HIM inorder to meet the requirements set forth in applicable

HIMSmart HART Loop


HART ParametersTo program the HART parameters, change the settingsin the Communications Settings box, then press QuickSet. See the descriptions below of the varioussections of the screen.

HART AddressThe HART Address is the address of the HART devicethat the HIM will be monitoring.

Number of RetriesThe Number of Retries can be set between 1 and 9,and will determine how many times the HIM willattempt to poll the HART transmitter (without success),before it indicates a HART Fault condition.

Normal/Burst/Listen (Passive) ModesThe HIM can operate in one of four modes: Normal,Burst, or Listen (Passive) and Listen (Specified Slave).In each of these modes, the HIM attempts to find aHART transmitter.

In Normal mode, the HIM polls the HART loop for atransmitter, then polls the HART instrument twice persecond, requesting the current process status and theHART instrument’s diagnostic status. The HARTinstrument responds with the requested data.

In Burst mode, the monitored HART instrument isprogrammed to continuously transmit its processvariable and health status. The HIM samples thecontinuous HART data three times per second.

Listen (Passive) mode allows the HIM to operate on aloop that already has primary and secondary HARTmasters. In Listen (Passive) mode, the monitorconnects passively, continuously sampling HART datafrom a smart instrument without affecting normal loopoperation. When using this mode, either the monitoredsmart HART instrument must be set in Burst Mode or aHART master must be continuously polling the smartHART slave device.

The HART protocol allows for two communicationsmasters on the loop, a Primary and a Secondary.Setting the HIM to function as the Primary HARTMaster in the application means that any other HARTdevice in the loop must be configured either as a HARTSecondary Master (1 per loop) or as a HART Slave (upto 16 per loop). Conversely, setting the HIM to functionas the Secondary HART Master allows other HARTdevices to function either as a Primary Master or asslaves. Configuring more than one device on a singleloop as a Primary or Secondary HART Master willcause a communications failure.

Listen (Specified Slave) When multiple HART instruments are present, theListen (Passive) mode cannot be used because datareturned from one instrument will overwrite the datapreviously stored in the HIM. If multiple HART slaveinstruments are communicating on the loop, the HIMwill overwrite its internal HART data sets with the latestdevice read from the bus, no matter where the dataoriginates. To allow selective monitoring on a multi-instrument loop, and to allow multiple HIMs to be usedon a digital loop, the Listen (Specified Slave) feature isused.

If the HIM is in “Listen” mode it is not a HART commu-nication master and therefore is not in control ofcommunication. Other HART masters are controllingthe polling of slaves and the HIM can only “Listen”.

The HIM must be able to detect when it has not heardfrom its assigned slave device so that it can declare a“No HART” input and force outputs to the valuesspecified by the user. The HIM must therefore be toldto wait an appropriate amount of time for the slavedevice to send its message before the HIM declares“No HART”. This timing coordination is accomplishedwith Timeout Period.

Timeout Period is a value between 1 and 30sec andmust be greater than the period between polls by theHART master of the Specified Slave. For example,assume that there are five HART transmitters on thesame multi-drop loop as the HIM. The HART master isconfigured to poll each device every second. It thentakes the HART master five seconds to repeat the pollto the one device being monitored by the HIM. the HIMTimeout Period must be set at a value greater than five

HIM



seconds. In this example, we will use seven seconds.The HIM then sees its slave device speak and waitsseven seconds for it to speak again. As long as theHIM sees a new message from its slave device itsoutputs are updated based upon the measured vari-ables. If the slave device does not speak within theseven second period, the HIM declares a “No HART”situation and sends its outputs to the failed communi-cations values.

To use this feature, proceed with the following steps:

1. Select the Listen (Specified Slave) button.

2. Enter your desired value into the Timeout Period(s)text box.

Factory default is 5 seconds. The maximum TimeoutPeriod is 30 seconds.

3. Set the exact slave address of the instrument youwish to monitor. Click the Set Slave Address button.This brings up the HART Slave Device Long FormatAddress Settings screen (Figure 8). Enter the requiredinformation into the appropriate text boxes.

The Manufacturer’s ID and Device Type ID for theinstrument that the HIM will listen to are available fromthe HART Foundation website at www.hartcomm.organd/or the instrument manufacturer.

Values obtained from the HART website are in HEXcode. The HIM does not use HEX code; you mustconvert this value to Decimal code.

Figure 8. HART Slave Device Long Format Address SettingsScreen

To convert HEX to Decimal code, perform thefollowing steps:

Access the Calculator feature in MicrosoftWindows® by opening the Start menu. Next,select Programs then Accessories and finallyCalculator.

Ensure that the Calculator is in Scientific mode.To do this, select the View dropdown menuand choose Scientific.

Click the Hex radio button and enter the HEXcode value.

Next, click the Dec button and the value will beconverted into the Decimal value.

Enter the converted value into the proper parameter.

The Device ID Number is the serial number ofthe exact device to which the HIM will listen.

4. Once complete, press OK.

Download the information to your instrument once youare finished.

Auto Clear Status BitMost HART instruments indicate when a device'sconfiguration has been changed. This indication(status bit) can be reset by sending HART command38–reset configuration changed. Checking the AutoClear Status Bit box causes the HIM to issue thiscommand whenever the HART instrument it ismonitoring has its configuration changed. However,the HIM can also be set to alarm on this bit (seeProgramming the Alarm Parameters). If the HIM isboth set to alarm and to auto clear, then it will doboth–going into alarm mode and resetting thatindication.

Quick Read/SetThe Quick Read button causes the PC ConfigurationSoftware to read the communications information fromthe attached HIM; the Quick Set button causes thesoftware to configure the HIM’s communicationssettings to match those of the PC Software.

Alarms ParametersThe Alarms tab controls the programmable alarmtrip(s) option. This screen will be grayed out if theattached HIM is not equipped with at least one alarmtrip. To program the Alarm parameters, change thesettings in the Alarm1 and/or Alarm2 box, then pressQuick Set. The sections of the screen are describedbelow.

Trip/Fault AlarmsA Trip Alarm monitors a selected variable and tripseither when the variable exceeds a set value (TripHigh) or when the variable falls below a selected value(Trip Low). The Source specifies which variable will bemonitored, while the Trip Point sets the point at whichthe alarm will trip. After the alarm trips, the DeadBand determines how far past the trip point thevariable will have to go before the alarm conditionreturns to normal.

There are two types of Fault Alarms. A HIM FaultAlarm monitors the health of the HART monitor. It willtrip whenever the internal error status word is set. Forexample, if the HIM’s configuration file becomescorrupt, this alarm will trip and the monitor will displayBAD_CONFIG. A Field Device Fault Alarm monitorsthe health of the HART transmitter. This fault alarmwill trip for any of these eight malfunctions:

Figure 10. Alarms Tab

Device Malfunction (Bit 7)Relay trips whenever it detects that a hardware error orfailure has occurred in the connected HART device.

Configuration Changed (Bit 6)Relay trips whenever it detects that the connectedHART device has had its configuration changed.

Cold Start (Bit 5)Relay trips whenever the power to the HART device isinterrupted. It will also trip during a HART MasterReset or Self Test Command.

Additional Status (Bit 4)Relay trips whenever the connected HART devicereports a condition requiring HART Command #48,which is Read Additional Information. This indicatesthat the instrument needs attention from a device withfull HART command capability.

Output Current Fixed (Bit 3)Relay trips whenever the HIM detects that theconnected HART device’s output is no longerresponding to changes in its input, and is being held ata predefined level.

PV Analog Output Saturated (Bit 2)Relay trips whenever it detects that both its analog anddigital representations of the Primary Variable areoutside rated operating limits, and no longer reflect thetrue sensor input.

Non-PV Out of Limits (Bit 1)Relay trips whenever one of the HART ancillaryvariables (second, third or fourth), is operating outsidethe limits that can be effectively measured.

PV Out of Limits (Bit 0)Relay trips whenever the HART Primary Variable isoperating outside the limits that can be effectivelymeasured.

Delay & Fail SafeBy entering a value in the Delay box, you can specifyhow long (in seconds) the alarm condition needs toexist before the alarm trips. Failsafe alarms (boxchecked) de-energize when in alarm condition;Non-Failsafe alarms energize when tripped.


HIMSmart HART Loop


HART Additional Status Alarm BitsHART Additional Status also called “More Status” and“Command 48” is where device manufacturers installthe custom diagnostics for the specific device. Foryour particular application, you may choose all of thesediagnostics to cause the HIM relay to trip or just onediagnostic bit to trip the HIM relay (or any combinationin between). The manufacturer of the HART device willbe the source for the specific diagnostic information.

Selecting the Field Device Fault Alarm function in theAlarms screen allows you to enable the HIM to setalarm states, when in fault mode, based on the bitsettings of the additional status information returned bycertain HART instruments. This provides flexibility tothe requirement of alarming on additional status infor-mation.

Choosing this feature, you are given the ability tospecify the bit(s) on which to alarm. To access thisfeature, check the Additional Status box. The Editbutton will appear in the HART Additional Status Bitssection of the screen. Clicking the Edit box brings upthe Additional HART Status Alarm Bits Settings window(Figure 11). Check the box(es) that correspond to thebits you wish to use; click OK.

Download the information to your instrument once youare finished.

HIM



Analog Outputs ParametersThe HIM comes with either two (–2AO) or three (–3AO)analog outputs. The Analog Outputs tab allows you tospecify which HART variable is to be monitored as thesource of the analog output, the input range and outputrange, and how the output will react when the variableinput is out of range. To program the Analog Outputsparameters, change the settings in the Output1/2/3boxes, then press Quick Set. See the descriptionsbelow of the various sections of the screen.

SourceSource defines the variable that the analog output willmonitor. Notice that selecting one of the scaledoutputs will require you to make changes to theScaling tab, and selecting the Custom Curve option willrequire you to make changes to the Custom Curve tab.

Input/Output RangeThe Input or Output Range defines the range of thesource input and the range of the analog output.These two sets of fields can be used to scale theHIM’s output.

Figure 12. Analog Outputs Tab

For example, you have a vortex flow meter with animbedded RTD that measures the processtemperature, and that temperature is assigned to theHART Secondary Variable. The full range of the RTDsensor is from –400°F to +1760°F, but your flowstream will always be between 0° and 400°F. To scalethe analog output, for Output 1, set the Source as SV.Set the Input Range to 0° and 400°F, and the OutputRange to 4mA to 20mA. Click Quick Set to downloadthe new configuration file to the HIM.

Output Current BoxThe Output Current Box on the Analog Outputs Tabdisplays up-to-the-second information on the value, inmA, of the analog output.

Fail ModeThe Fail Mode setting determines how the HIM willrespond when its monitored input fails. If Fail Mode isset to High and the measured input goes out of range,or any detected error occurs in the HART transmitter,the analog output will output a 23.6mA signal. If FailMode is set to Low and the measured input goes out ofrange, or any detected error occurs in the HARTtransmitter, the analog output will output a signal thatis 90% of the lower range value below 4mA; it willoutput 0mA if the lower range is set to 0mA.

If Fail Mode is set to Hold Last, the HIM will continueto output the last value it recorded before the inputfailed. If Fail Mode is set to Hold Last Then High orHold Last Then Low, the HIM will continue to output thelast value recorded for a set amount of time (accordingto Hold Last Duration box), then either fail high or faillow, respectively.

Quick Set ButtonThe Quick Set button causes the software to configurethe instrument’s analog output settings to match thosecurrently entered in the PC Software.

Trim ButtonThe Trim button brings up the Trim Menu, allowing youto set the device’s output to match the reading of theloop. Refer to the Programming the TrimmingParameters section of this manual for moreinformation.


HIMSmart HART Loop


Configuring Analog Output TrimmingThe Analog Output Trimming section of the softwareallows you to match the HART monitors analog outputto the output measured by a calibration device. Thiswill require a calibrated multimeter, such as a HP Model3478A or equivalent, accurate to ±0.009%.

Note:Trimming the analog output of the monitornullifies any scaling that may have been

performed in the Scaling tab.

User TrimmingTo trim the device, attach a multimeter to the analogoutput, then click the Fix Output at Low Point button.Read the value on the multimeter, enter it into theMeasured Output Loop Current portion of the Trimmingbox, and press Trim. Repeat this sequence until theanalog output matches the minimum point (4mA for a4-20mA output) when you click the Fix Output at LowPoint button.

After the low point is trimmed, press the Fix Output atHigh Point button. Read the value on the multimeter,enter it into the Measured Output Loop Current portionof the Trimming box, and press Trim. Repeat thissequence until the analog output matches themaximum point (20mA for a 4-20mA output) when youclick the Fix Output at High Point button.

When finished, press the Unfix Output button.

Figure 13. Trimming Window

Fix Current UtilityThe Fix Current Utility allows you to force the HIM tooutput any current value from 0-20mA. This can beused to match the calibration of your other equipment.To fix the current, simply enter the value in the Currentbox (in mA) that you want the HIM to output, and clickFix Output. When you are finished, make sure topress the Unfix Output button so that the HIM canreturn to normal operation.

Custom Curve ParametersThe custom curve tab allows you to set up a customcurve of up to 128 points. A custom curve can eitherbe created from scratch or loaded from a previouslycreated comma separated value (.csv) file. Toprogram the Analog Outputs parameters, change thesettings in the Custom Curve tab, then press DownloadTable. See the descriptions below of the varioussections of the screen.

ModeCheck the Enabled box to begin programming thecustom curve.

Source VariableThe Source Variable defines the variable that thecustom curve will calculate. Notice that if you select ascaled variable, you may need to click on the Scalingtab and verify the settings for your scaled variable.

Quick SetThe Quick Set button causes the software to configurethe HIM’s custom curve settings to match thosecurrently entered in the PC Software.

Scaling ParametersThe Scaling tab allows you to configure the values forscaled variables. To scale the selected variable, enterthe values into the appropriate boxes, then click on theTransfer menu and click Download to transfer the newscaled values to the HIM. (If any scaled variable wasselected in the Display, Alarm or Analog Outputs tabs,then the corresponding scaled variable section willbecome active for editing).

The HIM’s versatile scaling feature has many possibleapplications, as is shown in the illustration below.

Suppose you are using a digital pressure (DP)transmitter to measure the level of a tank in eithercentimeters/inches or PSI. Since the tank is only 300centimeters (10 feet) high, the full range of the primaryvariable (PV) output from the DP transmitter is 0-4.3PSI. You want to display the full level range (incentimeters/inches of water) on the HIM. You alsoneed to control the level from 50% to 100%, since thetank must be at least 50% full at all times. Finally,your existing loop indicator and level controller needs4-20mA to represent 150 to 300 centimeters (60 to 120inches) of water. How do you do this?

Scaling Illustration1. Since you want to display the full level range ininches of water (in H

2O) on the HIM, and the HIM is

reading PSI as the primary variable, first go to theDisplay tab and select Scaled PV as your displaysource.

2. Go to the Scaling tab and set up the PV Zero andPV Full values, and the Scaled PV Zero and Fullvalues. PV Zero would be 0 (PSI) and PV Full wouldbe 4.3 (PSI). Scaled PV would correlate to zero being0 in H

2O and full being 120 in H

2O. The HIM should

now (after downloading) display the full range inin H2O.

3. To manipulate the HIM’s analog output, go to theAnalog Outputs tab. Select Scaled PV as the Output 1source. Since you need to control the level from 50%to 100%, the Input Range should be 60 to 120 in H

2O

and the Output Range should be 4mA to 20mA.

Appendix A: HIM MODBUSFeatureThe HIM PC program allows you to configure theHART monitor. A HART Monitor with the MODBUSoption provides a digital MODBUS output to a con-nected MODBUS-based controller. Selecting theMODBUS tab allows you to set the MODSBUS com-munications parameters. Notice that the MODBUS tabwill only be available in units with the MODBUS option.

Figure A-1. MODBUS Tab

Comms SettingsThe Comms Settings include the following:

MODBUS AddressThe MODBUS Address is the number that the HIMmonitor uses to identify itself on the MODBUS net-work. The MODBUS address is configurable from 1 to247. By default, it will assume a MODBUS address of01.

Baud RateThe Baud Rate is the speed of data transmission. Itshould be set to match the baud rate of the attachedcontroller. The interface supports the following baudrates: 300, 600, 1200, 2400, 4800, 9600 and 19200.

ParityThe HART monitor supports even, odd and no Parity.The data format is one start bit, 8 data bits and onestop bit.

Floating Point Word OrderBy default, the HART monitor will use the StandardLSW (least significant word) floating point word orderformat. This stores the most significant bits in thesecond register and the least significant bits in the firstregister. Selecting Swapped MSW (most significantword) will reverse the order, storing the most signifi-cant bits in the first register and the least significantbits in the second register.

MODBUS RegistersThe HART Monitor outputs a MODBUS signal to theattached controller. To access the MODBUS registersfor variable, input/output or error information, refer toTable A-1 (MODBUS Register Definitons table) and/orTable A-2 (System Status Registers table).
