! ! # In this chapter, we describe: • checking your calibration • calibrating your module. $ ! ! " "! " Your module is shipped to you already calibrated. If you are checking calibration, or if it becomes necessary to recalibrate the module, you must do so with the module in an I/O chassis. The module must communicate with the processor and industrial terminal.
1–2 Calibrating Your Module If a calibration check of your module becomes necessary: 1. Verify that the module is in voltage mode. In single-ended mode, apply voltages to channels 1 through 16. 2. Send a configuration block transfer write to the module that replicates the specific application. (This forces the module to do an internal calibration.) 3. Apply –10V, –5V, –2.5V 0V, 1V, 2.5V, 5V, and 10V to the module.
Calibrating Your Module Calibrating your Input Module 1–3 The fast analog input module is shipped already calibrated. Calibration of the module consists of applying a voltage or current across each input channel for offset and gain calibration. Offset and gain values are shown in the following table. Table 1.
1–4 Calibrating Your Module The BTR echoes back the status of each of the channels to verify calibration. If selected channels were calibrated satisfactorily, the BTR will reflect this by having their bits set to 1. (In Differential mode, the upper byte of word 21 in the BTR is not set (bits 8–15 decimal or 10–17 octal are 0).
Calibrating Your Module 1–5 The BTR echoes back the status of each of the channels to verify the calibration. If all channels were calibrated satisfactorily, the BTW will reflect this by having all bits set to 1.

If a fault is found initially or occurs later, the red fault indicator lights.
In this chapter we describe: • block transfer programming • sample programs in the PLC-2, PLC-3 and PLC-5 processors • module scan time issues Your module communicates with your processor through bidirectional block transfers. This is the sequential operation of both read and write block transfer instructions.
Module Programming ! The PLC-2 program example regulates when each block transfer will be initiated to eliminate problems caused by limited regulation of bidirectional block transfers. Both storage bits are needed, as shown in the example, to accomplish this task in all PLC-2 systems, local or remote, with long or short program scans. Therefore, the program as shown is the minimum required.
Module Programming Block transfer instructions with the PLC-3 processor use one binary file in a data table section for module location and other related data. This is the block transfer control file. The block transfer data file stores data that you want transferred to your module (when programming a block transfer write) or from your module (when programming a block transfer read). The address of the block transfer data files are stored in the block transfer control file.
Module Programming The PLC-5 program is very similar to the PLC-3 program with the following exceptions: 1. You must use enable bits instead of done bits as the conditions on each rung. 2. A separate control file must be selected for each of the block transfer instructions. Refer to Appendix B. 7 329)5<83 7,) 352+5%0 )1%&/)6 % &/2'.
Module Programming Module Scan Time 5-5 Scan time is defined as the amount of time it takes for the input module to read the input channels and place new data into the data buffer. Word 24 of the block transfer write data table shows the scan time for the module for the given configuration. These figures are the time it takes to sample all channels and process the data. Refer to Appendix A for tables showing common scan times at various oversample rates. Table 10.
Module Programming The following description references the sequence numbers in Figure 5.4. Following a block transfer write “1” the module inhibits communication until after it has configured the data “2,” performed calibration check “3” (if requested), scanned the inputs “4,” and filled the data buffer “5.” Write block transfers, therefore, should only be performed when the module is being configured or calibrated. Any time after the second scan begins “6,” a BTR request “7” can be acknowledged.
In this chapter, we describe; • configuring your module’s features • conditioning your inputs • entering your data. 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.
During normal operation the processor transfers 1 to 41 words to the module when you program a block transfer write instruction to the module’s address. This BTW file contains configuration words, and calibration words (words 38 and 39) for each channel. When a block transfer transfer length of 0 is programmed, the 1771-IFF/A will respond with the 1771-IFE series A default length of 37. ! You can configure the module to operate with any of five voltage or three current ranges.

6-4 Two's complement binary, data first In two’s complement binary – data first mode, the channel data will appear in word 1 through 8 (differential) or 1 through 16 (single-ended). Diagnostic and status information which previously appeared in words 1 through 4 will appear after the channel data. Digital Filtering The module has hardware-based high frequency filters on all channels to reduce the effect of electrical noise on the input signal.
The real time sampling (RTS) mode of operation provides data gathered at precisely timed intervals for use by the processor. BTW word 3 bits 11–15 (13–17 octal) are used to set the real time sampling interval. RTS is invaluable for time based functions (such as PID and totalization) in the PLC. It allows accurate time based calculations in local or remote I/O racks.
Your module can perform linear conversion of unscaled data to engineering units, (for example; gallons/minute, degrees C, degrees F and pounds/square inch). Unscaled data in the module has a range of 0 through 4095 for the unipolar ranges (0 to 5V dc/0 to 20mA and 1 to 5V dc/4 to 20mA); and -4095 to +4095 (8190) for the bipolar ranges (+5V/+20mA and +10V). BTW words 6 through 37 are the scaling words for channels 1 through 16.
Scaling values must always be entered in BCD format, even if the data format chosen is binary. If scaling is selected for any channel, all channels must be scaled. If scaling is not required on certain channels, set those to the default input range: 0 to 4095 for 0 to + voltage or current ranges, and -4095 to +4095 for - to + voltage or current ranges. If scaling is not selected, the module requires specific minimum BTR file lengths for the number of channels used.
This feature (oversampling) is set in block transfer word 40. This word specifies the number of times a channel will be sampled and the results averaged. Legal values of the number of oversamples are: 0, 1, 2, 4, 8, 16, 32, 64, 128, and 256. The format of the data in this field can be BCD or binary.
6-9 Default Configuration If a write block of five words, with all zeroes, is sent to the fast analog input module (cat. no. 1771-IFF series A), default selections will be: • 1 to 5V dc or 4 to 20mA (dependent on configuration jumper • • • • • • • setting) BCD data format no real time sampling (RTS) no filtering no scaling single-ended inputs 8 times oversample no disabled channels Table 11.A Fast Analog Input Module (1771ĆIFF/A) Block Transfer Write Configuration Block Dec.

The 4-digit BCD format uses an arrangement of 16 binary digits to represent a 4-digit decimal number from 0000 to 9999 (Figure C.1). The BCD format is used when the input values are to be displayed for operator viewing. Each group of four binary digits is used to represent a number from 0 to 9.

Data Table Formats C–3 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.
