!Environment and Enclosure

This equipment is intended for use in a PollutionDegree 2 industrial environment, in overvoltageCategory II applications (as defined in IEC publication606641), at altitudes up to 2000 meters withoutderating.

This equipment is considered Group 1, Class Aindustrial equipment according to IEC/CISPRPublication 11. Without appropriate precautions, theremay be potential difficulties ensuring electromagneticcompatibility in other environments due to conductedas well as radiated disturbance.

This equipment is supplied as open type equipment.It must be mounted within an enclosure that is suitablydesigned for those specific environmental conditionsthat will be present, and appropriately designed toprevent personal injury resulting from accessibility tolive parts. The interior of the enclosure must beaccessible only by the use of a tool. Subsequentsections of this publication may contain additionalinformation regarding specific enclosure type ratingsthat are required to comply with certain product safetycertifications.

See NEMA Standards publication 250 and IECpublication 60529, as applicable, for explanations ofthe degrees of protection provided by different types ofenclosures. Also, see the appropriate sections in thispublication, as well as the AllenBradley publication17704.1, (Industrial Automation Wiring andGrounding Guidelines), for additional installationrequirements pertaining to this equipment.

!ATTENTION

This equipment is sensitive to electrostatic discharge,which can cause internal damage and affect normaloperation. Follow these guidelines when you handlethis equipment:

Touch a grounded object to discharge potentialstatic.

Wear an approved grounding wriststrap. Do not touch connectors or pins on component

boards. Do not touch circuit components inside the

equipment. If available, use a staticsafe workstation. When not in use, keep modules in appropriate

staticsafe packaging.

This manual shows you how to use your high resolution isolatedanalog series input/output modules with an Allen-Bradleyprogrammable controller. It helps you install, program, calibrate, andtroubleshoot your modules.

You must be able to program and operate an Allen-Bradleyprogrammable controller (PLC) to make efficient use of your analogmodule. In particular, you must know how to program block transferinstructions.

We assume that you know how to do this in this manual. If you donot, refer to the appropriate PLC programming and operationsmanual before you attempt to program this module.

In this manual, we refer to: the individual module as the module. the programmable controller, as the controller or the

processor.

This manual is divided into seven chapters. The following chartshows each chapter with its corresponding title and a brief overviewof the topics covered in that chapter.

You can install your module in any system that uses Allen-Bradleyprocessors that support block transfer and the 1771 I/O structure.

Contact your nearest Allen-Bradley office for more informationabout your programmable controllers.

These modules can only be used with 1771-A1B, A2B, A3B, A3B1,A4B or later 1771 I/O chassis and 1771-AM1, -AM2 chassis.Communication between the analog module and the processor isbidirectional. The processor block-transfers output data through theoutput image table to the module and block-transfers input data fromthe module through the input image table. The module also requiresan area in the data table to store the read block and write block data.I/O image table use is an important factor in module placement andaddressing selection. Refer to the table below.

Using this Manual P3

You can place your analog module in any I/O module slot of theI/O chassis.

Do not put the analog module in the same module group as a digitalhigh density module unless you are using 1 or 1/2-slot addressing.Avoid placing the analog module close to ac modules or high voltagedc modules.

features of the input/output modules how the modules communicate with programmable controllers

The high resolution isolated analog modules are intelligent blocktransfer modules that interface analog signals with Allen-BradleyPLC-3 and PLC-5 family programmable controllers that have blocktransfer capability. Block transfer programming moves input datawords from the modules memory to a designated area in theprocessor data table in a single scan. It also moves configurationwords and output data from the processor data table to modulememory.

The N-series family includes modules with both analog inputs andoutputs on the same module. The modules use 16-bitanalog-to-digital converters and 14-bit digital-to-analog convertersfor high resolution and accuracy. All of these modules require only asingle slot in the I/O chassis, and do not require an external powersupply.

Since the N-series modules are combination modules, with input andoutput capabilities on the same module, block transfer reads from themodule are structured differently from dedicated input or outputmodules. Normally, block transfer read information is contiguous,and is stored in contiguous locations in the data block. N-seriesmodules transmit channel data on an individual basis with statusinformation in between. This results in non-contiguous blocks ofdata in non-contiguous data locations. Care must be taken whentransferring this information. Additional programming may berequired.

IMPORTANTUse with PLC-2 family programmablecontrollers is not recommended. Refer tochapter 3, page 3-2.

Input data is converted to a specified data type in a digital format tobe transferred to the processors data table on request. Output data isconverted to analog signals and sent to the appropriate outputchannels. If real time sampling is selected, block transfer reads willonly occur at the time selected. Consequently, the minimum intervalbetween block transfer reads is the same as the total input updatetime for each analog input module (25ms).

12 Overview of the High Resolution Isolated Analog Modules

The modules have either four or eight channels, each electricallyisolated from each other and from the backplane. Input and outputterminations are made through prefabricated cables which connect toremote termination panels (RTP). The modules are compatible withall 1771-A1B, A2B, A3B, A3B1, A4B, and later 1771 universalI/O chassis. In addition, they can be used in 1771-AM1, and -AM2chassis.

The analog modules are comprised of modular analog signalconditioning blocks that are plugged into a common circuit board.

These signal conditioning blocks provide the following:

420mA output range 050mA output range +10V output (scalable +5V, 0-5V, 0-10V, etc.) thermocouple input (+100mV) +5V input (+20mA with resistor RTP) +10V input (+20mA with resistor RTP) 420mA input with sourcing/sinking input 1650 ohm RTD inputYour particular module may have a combination of the aboveconditioning blocks.

The N-Series analog modules feature:

scaling of data to engineering units self-calibration (external reference required) software configuration user-selectable high and low alarms with deadband (hysteresis) self diagnostics input open circuit detection programmable ramped outputs

Specific analog modules have these additional features:

Thermocouple input channels input channels configurable for thermocouple input ranges

14 Overview of the High Resolution Isolated Analog Modules

The processor transfers data to and from the module using BTW(block transfer write) and BTR (block transfer read) instructions inyour ladder diagram program. These instructions let the processorobtain input values and status from the module, and let you establishthe modules mode of operation (Figure NO TAG).

1. The processor transfers your configuration data, output data andcalibration values to the module using a block transfer writeinstruction.

2. External input devices generate analog signals that are transmittedto the module. Internal output circuitry generates analog signalsthat drive field devices.

3. The module converts the analog signals into binary or BCDformat and stores theses values until the processor requests theirtransfer.

4. When instructed by your ladder program, the processor performsa read block transfer of the values and stores them in a data table.

5. The processor and module determine that the transfer was madewithout error, and that input values are within specified range.

6. Your ladder program can use and/or move the data (if valid)before it is written over by the transfer of new data in asubsequent transfer.

See chapter 4, Configuring the Module, for more information.

The accuracy of each of the high resolution isolated analog modulesis described in Appendix A.

In this chapter you read about the functional aspects of the analogmodules and how they communicate with programmable controllers.

22 Installing the Module

Add this value to the requirements of all other modules in the I/Ochassis to prevent overloading the chassis backplane and/orbackplane power supply.

Place your module in any slot of the I/O chassis except for theextreme left slot. This slot is reserved for processors or adaptermodules.

Group your modules to minimize adverse affects from radiatedelectrical noise and heat. We recommend the following.

Group analog and low voltage dc modules away from ac modulesor high voltage dc modules to minimize electrical noiseinterference.

Do not place this module in the same I/O group with a discretehigh-density I/O module when using 2-slot addressing. Thismodule uses a byte in both the input and output image tables forblock transfer.

To install your module in an I/O chassis:

1. First, turn off power to the I/O chassis:

ATTENTION

!Remove power from the 1771 I/O chassisbackplane and disconnect the cable from themodule before removing or installing an I/Omodule.

Failure to remove power from the backplanecould cause injury or equipment damage due to

possible unexpected operation.

Failure to remove power from the backplanecould cause module damage, degradation ofperformance, or injury.

ATTENTION

!Observe the following precautions when insertingor removing keys:

insert or remove keys with your fingers make sure that key placement is correctIncorrect keying or the use of a tool can result indamage to the backplane connector and possiblesystem faults.

Field wiring to the remote termination panel is the same for allremote termination panel variations. Refer to Figure 2.4.

Each channel has 4 connections: R, I, O, and S.

R = return I = input O = output S = shieldChannel 1 would use R1, I1, O1, and S1; channel 2 would use R2,I2, O2, and S2; and so on for the remaining channels.

To connect field wiring to the remote termination panel:

1. Strip 3/8 inch (9.25 mm) of insulation from the 22-12 AWG wire.

2. Insert the wire into the open connector slot.

3. Tighten the screw to 4.45.2 lbin. (0.50.6Nm) to clamp thewire.

Figure 2.5 shows how to connect 4-wire sensors to the remotetermination panel. A 4-wire sensor has two pairs of leads; one pairfor each resistor junction. One wire of the four is not used (it doesnot matter which one). This leaves three wires one pair and onesingle wire. You must connect the single wire to the terminal markedO_. You connect the remaining pair of wires to terminals I_ andR_. It doesnt matter which wire of the pair connects to terminalI_ and which wire connects to terminal R_ so long as all threewires are the same AWG gauge.

The 1771-NIS, 1771-NBSC and 1771-NB4S modules aresourcing/sinking input modules. These modules can supply thenecessary loop power for 2-wire transmitters connected to the input.All loop power functionality is contained within the analog module.Examples of typical configurations are shown in Figure 2.6.No external resistors are required.

Inputs can be configured as sourcing or sinking inputs. For sourcinginputs, the N-series module supplies the loop power. For sinkinginputs, you supply the loop power.

When the loop power is supplied externally, the 16-bit resolutionprovides 65535 counts over the 020mA current range. Thisprovides about twice the resolution of voltage inputs with externalresistors.

If you are not using thermocouples, you can terminate the analogmodule to a terminal block by cutting the 25-pin RTP end connectoroff the standard cable and wiring to your terminal block. Refer toTable 2.B for wire termination designations.

When using shielded cable or shielded thermocouple extension wire,ground the foil shield and drain wire only at one end of the cable.We recommend that you wrap the foil shield and drain wire togetherand connect them to the S connection on the RTP for the particularchannel. All shield connections are internally connected together inthe RTP so that only one wire is required to ground the entire remotetermination panel. Connect a wire from the SH connection on theRTP to a ground stud on the metal cabinet in which the remotetermination panel is mounted.

If you do not want to ground a particular shield at the RTP, you canremove the jumper for that particular channel. This will allow theshield to float at the RTP end. To remove a jumper, you must cut itout. Once the jumper is removed it cannot be replaced. Clip asclose to the circuit board as possible at both ends to completelyremove it. The jumpers (Figure 2.7) are labeled J1 through J8,corresponding to channels 1 through 8 respectively.

At power-up, an initial module self-check occurs. The RUN/FLTindicator will be green when the check is completed satisfactorily. Itwill flash green until the first valid block transfer write has beenreceived. If a fault is found initially or occurs later, the RUN/FLTindicator turns red.

The bottom indicator is the calibrate/communication indicator. Thisindicator will flash green when doing block transfers. It will flash redduring calibration.

Possible module fault causes and corrective action are discussed inChapter 7, Troubleshooting.

A configuration BTW is initiated when the analog module is firstpowered up, and subsequently only when the programmer wants toenable or disable features of the module.

An output update BTW is initiated when the programmer wants theoutput channels on the module to change value. This shortenedversion of the BTW allows faster response time from the outputchannels.

The following example programs are minimum programs; all rungsand conditioning must be included in your application program. Youcan disable BTRs, or add interlocks to prevent writes if desired. Donot eliminate any storage bits or interlocks included in the sampleprograms. If interlocks are removed, the program may not workproperly.

32 Communicating With Your Analog Module

Your analog module works with a default configuration uponpowerup as long as a block transfer write (BTW) has not beeninitiated. See the configuration default section in chapter 4 tounderstand what this configuration looks like. Refer to the sampleprograms in this chapter to get started.

Your program should monitor status bits (such as overrange,underrange, alarms, etc.) and block transfer read activity.

The following example programs illustrate the minimumprogramming required for the 1771-N series module to powerup andoperate.

Due to the number of digits required for high resolution readings, the1771-N series modules normally read input values in 2s complementbinary. Binary coded decimal (BCD) can be used, but with lowerresolution. As a result, the 1771-N series modules are notrecommended for use with PLC-2 family programmable controllers.

Block transfer instructions with the PLC-3 processor use three datatable files. A binary file is used for module location and other relateddata. This is the block transfer control file. Two separate blocktransfer data files store data that you want transferred to the module(when programming a block transfer write) or from the module(when programming a block transfer read). The address of the blocktransfer data files are stored in the block transfer control file.

The industrial terminal prompts you to create a control file when ablock transfer instruction is being programmed. The same blocktransfer control file is used for both the read and writeinstructions for your module. A different block transfer control fileis required for every module.

An example program segment with block transfer instructions isshown in Figure 3.1, and described below.

Scan time is defined as the amount of time it takes for the module toread the input channels and place new data into the data bufferand/or read the data buffer and write new data to the output channels.Scan time for your module is shown in Figure 3.3.

The following description references the sequence numbers inFigure 3.3.

Following a block transfer write (1) the module inhibitscommunication until after it has configured the data and loadedcalibration constants (2), scanned the inputs and/or outputs (3), andfilled the data buffer (4). Configuration block transfers, therefore,should only be performed when the module is being configured orcalibrated.

Any time after the buffer is filled (4), a block transfer read (BTR)request can be acknowledged.

When operated in the default mode, new data will be available for aBTR every 25 milliseconds. When operated in real time samplemode (RTS = T), BTRs will be ignored by the module for Tmilliseconds, at which time a single BTR will be allowed.

The following are sample programs for using your modules moreefficiently when operating with the PLC-3 or PLC-5 familyprocessors.

These programs show you how to configure the module and readdata from the module, and efficiently update the output channels onthose modules with outputs.

Refer to the proper PLC-3 or PLC-5 documentation for additionalinformation on processor programming and data entry.

The differences between the types of 1771-N series modules isrelated to the number of output channels each module has. A modulewith only inputs (no outputs) requires one BTW after powerup.Thereafter, it sends back input data and module status by way ofBTRs.

A module with outputs requires BTWs to configure it and update itsoutput data. BTRs are required to send back input data and modulestatus.

In this chapter you will read how to:

configure your modules features condition your inputs and outputs and enter your data.

Because of the many analog devices available and the wide varietyof possible configurations, you must configure your module toconform to the analog device and specific application that you havechosen. Data is conditioned through a group of data table words thatare transferred to the module using a block transfer write instruction.

Configure your module for its intended operation by means of yourprogramming terminal and write block transfers.

Note: Programmable controllers that use 6200 software (release 4.2or higher) programming tools can take advantage of the IOCONFIGAddendum utility to configure this module. IOCONFIG Addendumuses menu-based screens for configuration without having to setindividual bits in particular locations. You must have blocktransfer read and block transfer write rungs in your programbefore using IOCONFIG software. Refer to your 6200 softwareliterature for details.

> It is strongly recommended that you use IOCONFIG toconfigure this module. The IOCONFIG utility greatlysimplifies configuration. If the IOCONFIG is notavailable, you must enter data directly into the datatable. Use this chapter as a reference when performingthis task.

Note: Programmable controllers that use process configuration andoperation software (cat. no. 6190-PCO) can take advantage of thosedevelopment and runtime tools used for the application ofprogrammable controllers in process control. The PCO worksheetsand the menu-driven configuration screens and faceplates let youconfigure, test/debug and operate the I/O module. Refer to your6190-PCO software literature for details.

During normal operation, the processor transfers from 1 to 59 wordsto the module when you program a BTW instruction to the modulesaddress. The BTW file contains configuration words, high and lowchannel alarm settings, and calibration values that you enter for eachchannel.

=

,

#

42 Configuring the Module

When making entries in the configuration block, use binary orhexadecimal only.

The modules can be operated in a default mode by using zeroes in allbut the first word of the BTW data file. The first word must identifythe number of outputs on the module. For example, the first wordfor the 8 output module (cat. no. 1771-NOC) would be 8880hexadecimal; the first word for the 2 out/6 input module (cat. no.1771-NBVC, -NBTC, -NBRC) would be 8820 hexadecimal; and thefirst word for the 8 input module (cat. no. 1771-NIV, -NT1, -NR)would be 8800 hexadecimal.

The default scaling values that apply to the inputs and outputs arelisted in the specifications in appendix A. In default mode, allprogrammable features (alarming, filtering, real time sampling, etc.)are disabled.

43Configuring the Module

Module level programming features include:

module configuration verification temperature scale data format real time sample

DE

The verify bit 00 in the block transfer write word 3 allows you tocompare the configuration information the module is using to theconfiguration information contained in a block transfer write (BTW).You set the verify bit in the BTW you wish to check, and downloadthe BTW to the module. After the BTW is completed, request a BTRfrom the module. The program verify field in the BTR (bits 09-10decimal, bits bits 11-12 octal, word 1) will contain either of twovalues: 10 (binary) indicates the verify failed; 11 (binary) indicatesthe verify succeeded.

If the verify bit is set, configuration information in the BTW data filewill not be used by the module regardless of the success or failure ofthe verify.

5

You select the temperature scale that the module will use whenreturning temperature to the processor using bit 01, word 3 of theblock transfer write data file. If the bit is set to 0, the temperature isin degrees C; if the bit is set to 1, the temperature is in degrees F.

8

Use bit 02, word 3 of the block transfer write data file to select a dataformat. If this bit is 0, all data fields will be in twos complementbinary format. If the bit is 1, all fields will be in BCD format. InBCD, the most significant bit is the sign bit for all signed fields. Thissign bit applies to both BTW and BTR words.

NOTE: Available resolution is poor when using BCD format.

The 4-digit BCD format uses an arrangement of 16 binary digits torepresent a 4-digit decimal number from 0000 to 9999 (Figure 4.1).The BCD format is used when the input values are to be displayedfor operator viewing. Each group of four binary digits is used torepresent a number from 0 to 9. The place values for each group ofdigits are 20, 21, 22 and 23 (Table 4.A). The decimal equivalent for agroup of four binary digits is determined by multiplying the binarydigit by its corresponding place value and adding these numbers.


The 1771-N series modules use 15-bit signed magnitude BCD. Themaximum range value available then becomes +7999.

Twos complement binary is used with PLC-3 processors whenperforming mathematical calculations internal to the processor. Tocomplement a number means to change it to a negative number. Forexample, the following binary number is equal to decimal 22.

101102 = 2210

First, the twos complement method places an extra bit (sign bit) inthe left-most position, and lets this bit determine whether the numberis positive or negative. The number is positive if the sign bit is 0 andnegative if the sign bit is 1. Using the complement method:

0 10110 = 22

To get the negative using the twos complement method, you mustinvert each bit from right to left after the first 1 is detected.

In the above example:

0 10110 = +22

Its twos complement would be:

1 01010 = -22

Note that in the above representation for +22, starting from the right,the first digit is a 0 so it is not inverted; the second digit is a 1 so it isnot inverted. All digits after this one are inverted.

If a negative number is given in twos complement, its complement(a positive number) is found in the same way:

1 10010 = -140 01110 = +14

All bits from right to left are inverted after the first 1 is detected.

The twos complement of 0 is not found, since no first 1 is everencountered in the number. The twos complement of 0 then is still 0.

# 5

Real time sampling is set using word 4 of the block transfer writedata file. The real time sampling (RTS) mode of operation providesdata from the module at a fixed time period for use by the processor.RTS is invaluable for time based functions (such as PID andtotalization) in the processor. It allows accurate time basedcalculations in local or remote I/O racks.


In the RTS mode, the module scans and updates its inputs at a userdefined time interval (T) instead of the default interval. Themodule ignores block transfer read (BTR) requests for data until thesample time period elapses. The BTR of a particular data setoccurs only once at the end of the sample period and subsequentrequests for transferred data are ignored by the module until a newdata set is available. If a BTR does not occur before the end of thenext RTS period, a time-out bit is set in the BTR status area (word1). When set, this bit indicates that at least one data set was nottransferred to the processor. (The actual number of data sets missedis unknown.) The time-out bit is reset at the completion of the BTR.

Legal RTS values are in intervals of 1ms from 0.100 to 10.000seconds in binary format, or 0.100 to 9.999 seconds in BCD format.An RTS value of 0 disables the real time sampling feature.

Output channel programming features include:

low and high scaling low and high clamping ramping alarm enable reset state reset value

5

Scaling is the conversion of unscaled data to engineering units. Youuse scaling so that the data for each channel is represented in actualengineering units.

Each channel has two scaling points, low and high. The signal valueat these points is fixed. For example, the high scaling point of a+10V output channel always corresponds to an output signal equal to+10.000V.

This value specifies the time constant for a digital first order lagfilter on the input. It is specified in units of 0.1 seconds. Values rangefrom 0.1-9.9 seconds in BCD and 0.1-10.0 seconds in binary. Avalue of 0 disables the filter.

The digital filter equation is a classic first order lag equation(Figure 4.6). Using a step input change to illustrate the filterresponse (Figure 4.7), you can see that when the digital filterconstant time elapses, 63.2% of the total response is reached. Eachadditional time constant achieves 63.2% of the remaining response.

In this chapter you will read about:

reading data from your module block transfer read data format

Block transfer read (BTR) programming moves status and data fromthe module to the processors data table in one I/O scan. Theprocessor user program initiates the request to transfer data from themodule to the processor.

The transferred words contain module status, channel status andinput data from the module. The maximum BTR data file lengthrequired is 28 words.

Block transfer reads are defined for each type of module platform,rather than type of outputs/inputs. The types of modules are:

Each output channel also has two words associated with it. The firstword contains low and high clamp, rate alarm, bad data, bad programand bad calibration information for the processor. This is followedby raw count data for that channel. If the module contains both inputand output channels, the output channel words would immediatelyfollow the header words.

Example: Using a 649 ohm resistor, rated for 1% accuracy, with atemperature coefficient of 50ppm/oC, provides an expected accuracyof 1.05% (1.0% plus 0.05%) when calibration is done at 35oC (Tof 10oC).

The analog module is shipped already calibrated. If it becomesnecessary to recalibrate the module, you must calibrate the module inan I/O chassis. The module must communicate with the processorand an industrial terminal.

Calibration service is available from AllenBradley. Contact yourlocal sales office or field support center for information on how tosend your module in for calibration. Modules under warranty will becalibrated at no charge. Modules out of warranty, sent in forcalibration only, will be calibrated for less than the standard repaircharge.

Before calibrating the module, you must enter ladder logic into theprocessor memory, so that you can send block transfer data to themodule, and the processor can read block transfer data from themodule.

Calibration can be accomplished using any of three methods:

.

63Module Calibration

manual calibration refer to the procedure below. 6200 I/O CONFIG software refer to your 6200 software

publications (release 4.2 or later) for procedures for calibrating.

PCO operator interface software refer to your 6190-PCOsoftware publications for procedures for calibrating.

During calibration, the RUN/FLT indicator will turn to green. TheCAL/COM indicator will turn to flashing red. The indicators willremain with these indications throughout the calibration procedure.

You can calibrate any number of channels, in any order. Thefollowing procedures define how to calibrate input and outputchannels.

IMPORTANTIn order to allow the module to stabilize,energize the module for at least 30 minutesbefore calibrating.

Set up a block transfer write data file as shown in table 6.C.

1. Set the appropriate bit in the BTW input calibration mask (word2); channel 1 is bit 00, channel 2 is bit 01, etc. If calibrating onlyone channel, set the appropriate bit. If calibrating all channels (allinputs), set bits (00 through 07). Refer to Table 6.C.

Design your program to monitor module and channel status bits, andto take appropriate action depending on your applicationrequirements. You may also want to monitor these bits whiletroubleshooting with your industrial terminal. The module sets a bit(1) to indicate it has detected one or more of the following moduleconditions as shown in Table 7.B.

The module sets a bit (1) to indicate it has detected one or more ofthe following input channel conditions (Table 7.D), or output channelconditions (Table 7.C).
