Chapter 1 Overview of the High Resolution Isolated Analog Modules Chapter Objectives This chapter gives you information on: • features of the input/output modules • how the modules communicate with programmable controllers Module Description The high resolution isolated analog modules are intelligent block transfer modules that interface analog signals with Allen-Bradley PLC-3 and PLC-5 family programmable controllers that have block transfer capability.
PAGE 16
1–2 Overview of the High Resolution Isolated Analog Modules The modules have either four or eight channels, each electrically isolated from each other and from the backplane. Input and output terminations are made through prefabricated cables which connect to remote termination panels (RTP). The modules are compatible with all 1771-A1B, A2B, A3B, A3B1, A4B, and later 1771 universal I/O chassis. In addition, they can be used in 1771-AM1, and -AM2 chassis.

2–2 Installing the Module Add this value to the requirements of all other modules in the I/O chassis to prevent overloading the chassis backplane and/or backplane power supply. Determine Module Location in the I/O Chassis Place your module in any slot of the I/O chassis except for the extreme left slot. This slot is reserved for processors or adapter modules. Group your modules to minimize adverse affects from radiated electrical noise and heat. We recommend the following.
PAGE 21
Installing the Module 2–3 Key the Backplane Connector Place your module in any slot in the chassis except the leftmost slot which is reserved for processors or adapters. Position the keying bands in the backplane connectors to correspond to the key slots on the module. Place the keying bands: between 26 and 28 between 32 and 34 I/O chassis Keying Bands You can change the position of these bands if subsequent system design and rewiring makes insertion of a different type of module necessary.

2–8 Installing the Module Field wiring to the remote termination panel is the same for all remote 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 = shield Channel 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.
PAGE 27
2–9 Installing the Module Connecting 4ĆWire Sensors Figure 2.5 shows how to connect 4-wire sensors to the remote termination panel. A 4-wire sensor has two pairs of leads; one pair for each resistor junction. One wire of the four is not used (it does not matter which one). This leaves three wires – one pair and one single wire. You must connect the single wire to the terminal marked “O_”. You connect the remaining pair of wires to terminals “I_” and “R_”.
PAGE 28
2–10 Installing the Module Sourcing Input Analog Modules The 1771-NIS, 1771-NBSC and 1771-NB4S modules are sourcing/sinking input modules. These modules can supply the necessary 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. Figure 2.
PAGE 29
Installing the Module Making Your Own Cables 2–11 If you are not using thermocouples, you can terminate the analog module to a terminal block by cutting the 25-pin RTP end connector off the standard cable and wiring to your terminal block. Refer to Table 2.B for wire termination designations. Table 2.
PAGE 30
2–12 Installing the Module Grounding the Field Devices 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 together and connect them to the “S” connection on the RTP for the particular channel. All shield connections are internally connected together in the RTP so that only one wire is required to ground the entire remote termination panel.
PAGE 31
2–13 Installing the Module Interpreting the Indicator Lights The front panel of the analog module contains two bi-color indicators: a red/green RUN/FLT (fault) indicator and a red/green CAL/COM indicator (Figure 2.8). Figure 2.8 Diagnostic Indicators RUN/FLT CAL/COM Run/Fault indicator. This indicator will flash green until the first valid block transfer write has been received. If a fault is found initially or occurs later, the RUN/FLT indicator turns red. Calibrate/communication indicator.

Chapter 3 Communicating With Your Analog Module Chapter Objectives In this chapter, we describe • block transfer programming • quick-startup sample programs for the PLC-3 and PLC-5 processors • module scan time issues Block Transfer Programming Your module communicates with the processor through bidirectional block transfers. This is the sequential operation of both read and write block transfer instructions.
PAGE 34
3–2 Communicating With Your Analog Module Your analog module works with a default configuration upon powerup as long as a block transfer write (BTW) has not been initiated. See the configuration default section in chapter 4 to understand what this configuration looks like. Refer to the sample programs in this chapter to get started. Your program should monitor status bits (such as overrange, underrange, alarms, etc.) and block transfer read activity.
PAGE 35
3–3 Communicating With Your Analog Module Figure 3.1 PLCĆ3 Family Sample Program Structure Program Action At powerup, the user program enables a block transfer read. Then it initiates a block transfer write to configure module. Thereafter, the program continuously perĆ forms read and write block transfers.
PAGE 36
3–4 Communicating With Your Analog Module Module Scan Time Scan time is defined as the amount of time it takes for the module to read the input channels and place new data into the data buffer and/or read the data buffer and write new data to the output channels. Scan time for your module is shown in Figure 3.3. Figure 3.
PAGE 37
3–5 Communicating With Your Analog Module The differences between the types of 1771-N series modules is related to the number of output channels each module has. A module with only inputs (no outputs) requires one BTW after powerup. Thereafter, it sends back input data and module status by way of BTRs. A module with outputs requires BTWs to configure it and update its output data. BTRs are required to send back input data and module status.
PAGE 38
3–6 Communicating With Your Analog Module Modules without output channels do not require rungs 2 and 3. Instead, move the input condition instructions from rung 2 to the front of rung 4, and specify the BTW length equal to 59. Sample Ladder Diagram Ć PLCĆ5 Family Processors The following PLC-5 program is very similar to the preceding PLC-3 program with the following exceptions: • You use enable bits instead of done bits as the conditions on each rung.

Chapter 4 Configuring the Module Chapter Objectives In this chapter you will read how to: • configure your module’s features • condition your inputs and outputs and • enter your data. Configuring the High Resolution Isolated Analog Modules Because of the many analog devices available and the wide variety of possible configurations, you must configure your module to conform to the analog device and specific application that you have chosen.
PAGE 42
4–2 Configuring the Module When making entries in the configuration block, use binary or hexadecimal only. Default Configurations The modules can be operated in a default mode by using zeroes in all but the first word of the BTW data file. The first word must identify the number of outputs on the module. For example, the first word for the 8 output module (cat. no. 1771-NOC) would be 8880 hexadecimal; the first word for the 2 out/6 input module (cat. no.

Configuring the Module 4–5 Two's Complement Binary Two’s complement binary is used with PLC-3 processors when performing mathematical calculations internal to the processor. To complement a number means to change it to a negative number. For example, the following binary number is equal to decimal 22. 101102 = 2210 First, the two’s complement method places an extra bit (sign bit) in the left-most position, and lets this bit determine whether the number is positive or negative.
PAGE 46
4–6 Configuring the Module In the RTS mode, the module scans and updates its inputs at a user defined time interval ∆( T) instead of the default interval. The module ignores block transfer read (BTR) requests for data until the sample time period elapses. The BTR of a particular data set occurs only once at the end of the sample period and subsequent requests for transferred data are ignored by the module until a new data set is available.

Configuring the Module 4–9 Clamping Output channels can be configured to limit or clamp the output signal at a specified value regardless of the output data value written to the module. Low and high clamping values are written to the module in scaled units, and must be within the absolute signal limits shown below. Output Type Low Absolute Limit High Absolute Limit + 10V Ć10.4V 10.
PAGE 50
4–10 Configuring the Module Ramping Output ramping is used to limit the rate of change of an output channel. You enter the rate as a percentage (between 0 and 200%) of full scale per second, where 0 disables the ramping feature, and full scale is the difference between the low and high scaling points. 4.3 shows the effect of ramping on the output signal. Figure 4.
PAGE 51
Configuring the Module 4–11 Reset Value If the channel is programmed to go to a user-selectable reset value upon I/O reset, the value is entered (in scaled units) into that channel’s proper configuration word. The value entered must be between the high and low absolute limits. If user-selectable resetting is not chosen, this field should be set to 0.

4–12 Configuring the Module • Overrange - This bit is set if the input rises above the maximum range for that specific input type. This alarm is predefined and cannot be changed by the user. For all voltage, RTD and thermocouple inputs, this bit indicates an open channel. Alarm Deadband Alarm deadband allows the user to program a hysteresis effect on the alarming for a given channel.
PAGE 53
Configuring the Module 4–13 Rate Alarm This bit is set when the input changes at a rate faster than the user-defined value. Rate of change values can range from 0.05% to 50% of the input’s full scale range per second. Full scale range is defined as the difference between the high scale value and the low scale value. The rate is specified in scaled units per second. Figure 4.

Chapter 5 Module Status and Input Data Chapter Objectives In this chapter you will read about: • reading data from your module • block transfer read data format Reading Data from the Module Block transfer read (BTR) programming moves status and data from the module to the processor’s data table in one I/O scan. The processor user program initiates the request to transfer data from the module to the processor. The transferred words contain module status, channel status and input data from the module.
PAGE 62
5–2 Module Status and Input Data Block Transfer Read Data Format The block transfer read data format consists of an initial block header which identifies the type of module (input, output, or output/input), and groups of words that contain information on either an input channel or an output channel. Output channel words are configured immediately after the block header. If the module contains both output and input channels, the output channel words come first in the block transfer read data format.

5–3 Module Status and Input Data Word Decimal Bit (Octal Bit) Definition Bit 13 (15) Module alarm. This bit is set if there is an alarm bit set for one or more channels. The input alarm bits are low, high alarm and rate alarm. The output channel alarm bits are low and high clamp, and the rate limit alarm. Bit 14 (16) Bad channel data. This bit is set if the module is in BCD mode and one or more of the input data values sent in the last BTW are not legal BCD values. Bit 15 (17) Powerup bit.
PAGE 64
5–4 Module Status and Input Data Word Decimal Bit (Octal Bit) Definition Bit 08 (10) Module fault.
